This study aimed to assess protein enrichment of sterile and non-sterile cassava pulp using four strains of Aspergillus niger – AN1, AN2, AN3, AN4. First, studies were conducted to evaluate nutritional requirements of A. niger strains and their suitability for protein enrichment of cassava pulp. Second, sterile and non-sterile cassava pulps were inoculated with spores of A. niger strains and incubated under conditions of solid-state fermentation for 8 days using standard methods. Protein contents of sterile and non-sterile cassava pulps were determined by the Kjeldahl method. Initial nutritional requirements studies showed that A. niger strains grew at rates between 2.0 cm and 8.5 cm over 10 days on potato dextrose agar medium of different pH. The dry weight of mycelia of A. niger strains varied in liquid media separately supplemented with different concentrations of thiamine, ammonium nitrate and sodium chloride. A. niger strains also showed different levels of sporulation when cultured in growth media supplemented with different concentrations of sodium chloride. Increases in protein contents of sterile cassava pulp by AN1, AN2, AN3 and AN4 were 15.65%, 22.61%, 18.30% and 19.13%, respectively. On non-sterile cassava pulp, the increases in protein content by AN1, AN2, AN3 and AN4 were 15.40%, 21.54%, 10.80% and 3.85%, respectively. A. niger strain AN2 was the most suitable strain for the enrichment of protein content of cassava because it sparsely produced spores, it had the highest mycelial growth and resulted in the greatest increase in protein content of both sterile and non-sterile cassava pulp.

Studies on fungal species consortia of manglicolous fungi are very few. Observations of fungal species consortia may provide an idea on the fungal community structures and help in understanding ecosystem dynamics. In this paper, the fungal species consortia recorded on Nypa fruticans at Brunei is presented. Astrosphaeriella striatispora, Linocarpon appendiculatum, L. bipolaris, Neolinocarpon globosicarpa, Oxydothis nypae and Trichocladium nypae, were the frequently recorded fungi in this study. Three distinct fungal assemblages were found. One of these assemblages was typified by Astrosphaeriella striatispora, Linocarpon nypae and Oxydothis nypae in which the fungi occurred both in association with others as well as singly indicating a commensalistic occurrence. The second assemblage, was characterized by Linocarpon appendiculatum and Linocarpon bipolaris, the fungi occurred almost only in association with others, indicating a mutualistic behavior. The third assemblage was characterized by Anthostomella eructans, Anthostomella sp. and Trichocladium sp. which always occurred singly, indicating a possible antagonistic life style but the percentage occurrence of the last group was far low to attribute any antagonistic potential of these fungi in preventing other fungi from colonization.

The fruticose lichen Usnea is a cosmopolitan genus also found in the mountains of the Philippines. Despite its abundance, though, this lichen genus is not extensively studied in the country. Since the Philippine Usnea holds great potential in pharmaceutical and agricultural research, the basic knowledge on this lichen is important to establish. Therefore, this paper takes a detailed review of Usnea in the Philippines and summarizes all the literatures that have been conducted on it in all aspects. Further, the provinces that were already reported of the occurrence of this genus are plotted in one figure to also highlight those that have not been explored yet. Currently, 81 species of Usnea were reported in the country. This includes a species that was previously under the genus Usnea but has been arguably reclassified to a different genus in the present (i.e., Eumitria). This review also hopes to direct future studies regarding Usnea.

Madhuca latifolia is an economically important medicinal and oil yielding plant of India having slow growth rate. As microbial application to the rhizosphere of host plant are beneficial for growth and development of plants, a comprehensive experimental study by using native microflora of Madhuca latifolia had been carried out in the nursery conditions. Isolation and identification of native rhizospheric soil revealed the occurrence of 17 different types of bacteria (gram negative and positive) and 30 numbers of fungi belonging to myceloid type, Aspergillus, Alternaria, Colletotrichum, Fusarium and Penicillium. Present study was confined to phosphate solubilizing microbes for which solubilization potential (solubilization index and solubilization efficiency) was evaluated. Inoculation experiments in pot culture with red laterite soil were set in two experimental categories (1) non-transplanted and (2) transplanted. Plants grown under both the conditions with and without microbial application were maintained up to 120 days and final data recorded for morphological, physiological growth and as soil parameters. The mineral solubilizing potential of native microbial strains has been expressed. Fungal inoculants were more effective than the bacterial inoculants as far as the growth and development of plants concerned. Among all, bacteria MLB-1, MLB-6, Aspergillus terreus and non-sporulating dematiaceous form of fungi were prominent in improving plant growth. This has also been confirmed the useful and beneficial impact of indigenous organism. The records made during the study is useful for development of bioinoculants for forest trees, nursery of quality planting material which will also helps in establishment at plantation site.

Investigations were done to obtain potential phosphate solubilising strains from endophytic mycoflora isolated from the orchid, Pomatocalpa decipiens. 928 endophytic phosphate solubilising fungal isolates were obtained from 2400 leaf segments (0.38% recovery) from rare epiphytic orchid Pomatocalpa decipiens present in the Barbara hills of Odisha (India). A number of isolates belonged to different genera such as Paecilomyces, Curvularia, Aspergillus, Cladosporium, Penicillium, Colletotrichum, while others, which were unidentified were classified as mycelia sterilia. Root sampling done from 25 different sites resulted in isolation of 20 endophytic phosphate solubilising fungal isolates from 300 segments (0.1% recovery). Aspergillus, Paecilomyces, Fusarium, Penicillium, and mycelia sterilia were mostly obtained. The qualitative and quantitative assessments of Phosphate (P) solubilisation were performed using TCP and Rock phosphate as P source for those strains. Aspergillus niger (leaf isolate) showed a maximum of 33.2 and 22.7 % solubilisation in presence of TCP and Rock phosphate respectively whereas Aspergillus niger (Root isolate) showed a maximum of about 23.9% and 36.2% solubilisation in presence of TCP and Rock phosphate respectively.

Amomum villosum, Aquilaria sinensis, Morinda officinalis, and Pogostemon cablin are well-known medicinal plants in South China for their particular pharmacological activities, but their endophytic fungi have been rarely reported. Here, the endophytic fungal communities associated with the leaves, stems, and roots of the four medicinal plant species were investigated by high-throughput sequencing technology. From the four medicinal plant species, a total of 169,149 sequences (reads) of endophytic fungi were harvested and clustered into 791 operational taxonomic units (OTUs) assigned to the Kingdom Fungi. These OTUs taxonomically spanned five phyla, 27 classes, 75 orders, 167 families, and 291 genera. At the genus level, Phyllosticta, Candida, Zasmidium, and Cryptococcus were the major genera detected in A. villosum; Nigrospora, Tylopilus, Arthrobotrys, Coniosporium, and Corynespora were the dominant genera isolated in A. sinensis; Ochroconis, Cercospora, Aspergillus, and Cyphellophora were the dominant genera detected in M. officinalis; and Cladophialophora, Meira, Sakaguchia, and Penicillium were the major genera isolated in P. cablin. Among the four medicinal plant species, M. officinalis had the highest endophytic fungal diversity (H′>4.25), however A. sinensis had the lowest (H′<2.37). There were significant differences in endophytic fungal communities among different organs in the same plant species.

Sexual morph of didymellaceous taxa are characterized by their ascomata with relatively thin peridium, cylindric-clavate to clavate, short-pedicellate or apedicellate asci, hyaline to brown, 1-septate to muriform ascospores. Its asexual morphs are coelomycetous and comprising pycnidial or acervulus conidiomata, phialidic, hyaline conidiogenous cells and hyaline or pale brown, septate or aseptate conidia. The majority of these cosmopolitan species are plant associated fungi which can be pathogens on a wide range of hosts and some species are of particular relevance for quarantine measures. Recent studies have significantly improved the taxonomy and systematics of didymellaceous taxa based on molecular phylogenetics. In contrast to the accurate and detailed studies on the asexual morphs which are common obligate pathogens, information on their usually saprobic sexual morphs is still limited. Among these phenotypically diverse species, spore characteristics are quite unique as most have hyaline spores with 0–1 septum, while only Neomicrosphaeropsis and Didymellocamarosporium are reported as producing pigmented, muriform spores. These dematiaceous muriform spores are characteristic of a considerable number of species that may be quite divergent in other characters. During taxonomic investigations on the diversity of didymellaceous taxa, we have isolated species from Alhagi pseudalhagi, Coronilla emerus, Cytisus sp., Elaeagnus angustifolia and Spartium junceum in Italy, Russia and Uzbekistan. A comprehensive phylogeny, based on four loci (ITS, LSU, rpb2 and tub2) is used to infer species relationships. Comprehensive morphological descriptions and in-depth phylogenetic investigations of five new species viz. Ascochyta coronillae-emeri, Microsphaeropsis spartii-juncei, Neomicrosphaeropsis alhagi-pseudalhagi, N. cytisicola and N. elaeagni are presented.

This study is to assess the biotechnological potential of agro-industrial wastes of pineapple (Ananas comosus), sweet potato (Ipomoea batatas) and watermelon (Citrullus lanatus) for protein enrichment by solid-state fermentation using Aspergillus niger. Spore suspensions of A. niger were prepared with potato dextrose broth that had been supplemented with sodium chloride, ammonium nitrate and thiamine, and adjusted to pH of 5. Initial protein contents of sterile and non-sterile wastes of the pineapple, sweet potato, and watermelon were determined by the Kjeldahl method. The remaining sterile and non-sterile wastes was inoculated with spore suspensions of A. niger and incubated at temperature of 24°C under conditions of solid-state fermentation for 14 days. Protein contents of the inoculated sterile and non-sterile wastes were determined after 7 and 14 days. The sterile wastes of pineapple, sweet potato and watermelon recorded initial percentage protein contents of 4.37, 4.39, and 10.89, respectively, whereas their corresponding non-sterile wastes recorded initial percentage protein contents of 3.76, 4.00, and 10.16, respectively. The results further show that percentage increase in protein content of sterile wastes after 14 days of fermentation were pineapple, 35.01%; sweet potato, 27.60%; and watermelon, 64.40%. Percentage increase in protein content of non-sterile wastes after 14 days of fermentation were pineapple, 72.34%; sweet potato, 85.25%; and watermelon, 80.51%. These findings affirm the biotechnological potential of pineapple, sweet potato and watermelon wastes and the importance of fungi as agents for protein enrichment of agro-industrial wastes.

The study on the effects of environmental factors and host characteristics on diversity and distribution of wood-rotting fungi Mount Puliebadze, Nagaland was carried out for a period of two successive years (January 2015 to December 2016). A total of 46 wood-rotting fungi belonging to 16 families were identified. The occurrence of wood-rotting fungi demonstrated a decreasing trend with increase in elevations and correlation between the two variables showed a strong negative correlation with Pearson’s correlation coefficient (r) value of -0.993. The zone with lowest elevation (zone 1) comprised maximum number of species (25 species) whereas the zone with highest elevation (zone 4) comprised minimum number of species (05 species). Highest species similarity percentage (25.9%) was observed between zone 2 and 3. One way ANOVA showed significant variations between the occurrence of wood-rotting fungi with different seasons, light intensity, type of substrata and decay stage of wood. Shannon’s diversity index (H’) of zone 1 was highest (H’= 3.073) and that of zone 4 was lowest (H’ = 1.242).

We report differences in secondary resource capture and upper lethal temperature as survival attributes for Fusarium oxysporum (FOSC) and Rhizopus stolonifer, two medically important fungi that were co-isolated from a table shower caddy. Isolates of these two shower-associated fungi have been deposited at the University of Alberta Microfungus Collection and Herbarium, Centre for Global Microfungal Biodiversity (UAMH, Toronto, CAN) as R. stolonifer UAMH 11965 and F. oxysporum (FOSC) UAMH 11966; this paper provides growth characteristics for these two strains that can be used for further studies on black molds in bathrooms given the relevance to public health. Both R. stolonifer UAMH 11965 and F. oxysporum (FOSC) UAMH 11966 require contact with a wet surface substrate with water activity ≥ 0.95 aw for growth and sporulation. In contrast to F. oxysporum, R. stolonifer has a 4-6x, faster radial growth rate, superior colonizing ability, and capacity for overgrowth (exploitative competition). This F. oxysporum (FOSC) strain, however, is thermotolerant, as demonstrated by broader thermal growth range and higher optimum temperature, which puts fewer limitations on its growth compared to R. stolonifer. This is a point of public awareness for mold-sensitive and immunocompromised people that wet, wood substrates in a shower can permit colonization and competitive interactions that can concentrate R. stolonifer and F. oxysporum spores.

The antifungal activities and phytochemical screening of two invasive alien species: Ageratina adenophora and Ipomoea carnea ssp. fistulosa of Nepal were studied. Distilled water and methanolic extract of the leaves of plants were tested against five phytopathogenic fungi viz. Alternaria brassicae, Botrytis cinerea, Fusarium oxysporum, Phytophthora capsici and Sclerotium rolfsii at five different concentrations (50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ml, 250 mg/ml). The antifungal activity was performed by poisoned food technique; and linear mycelium growth reduction (LMGR) percentage was calculated. A qualitative phytochemical screening was performed for constituents such as tannins, saponins, terpenoids, alkaloids and flavonoids. The methanolic extract was more efficient as compared to the distilled water extract. A. brassicae, B. cinerea and S. rolfsii were found the most resistant fungi and F. oxysporum was found the most susceptible fungus. Out of two plants, A. adenophora was found more active against selected pathogens than Ipomoea carnea ssp. fistulosa. It can be concluded that the tested plants possess antifungal properties which may be used as alternative fungicides after further investigation.

During the collection of manglicolous lichens for the project work on pharmacological evaluation, three lichen species collected from a remote “Lanka” in less known Vainateya Godavari river basin in the year 2015. There is no record of any of these lichen species on the mangroves of Andhra Pradesh like Dirinaria consimilis (Stirton) D. D. Awasthi, Parmotrema tinctorum (Despr. ex Nyl.) Hale and Roccella montagnei Bel. em. D. D. Awasthi on the host is Excoecaria agallocha. Interestingly the authors find no such lichen flora even in the Coringa wild life sanctuary the second largest stretch of mangrove forests of India due to its close proximity to the port city of Kakinada.

A total of thirty three (33) endophytic fungi including sterile mycelia were isolated from the leaf, stem and roots of medicinally important aromatic plant Gaultheria fragrantissima. Majority of the fungi belonged to the phylum Ascomycota. The total percentage colonization frequency (% CF) of each endophytic fungal species was calculated of which Juxtiphoma eupyrena showed highest colonization frequency (20.14%) in the leaf whereas Globisporangium irregulare was found to have highest colonization frequency in the stem (14.58%) and in the roots, Trichoderma viride was observed to have the highest colonization frequency of 21.43%. Diversity of endophytic fungi in the roots was found to be higher as compared to the other plant tissues.

Microfungi are fundamental organisms help in balancing the ecosystem. The aims of this study are to identify microfungi isolated from sandy beaches based on internal transcribed spacers (ITS) sequence analysis and to determine the phylogenetic relationship among the locations of sampling areas. Fifty-seven isolates of microfungi were obtained from six beaches located in Kedah (Chenang Beach), Pahang (Balok Beach) and Sabah (Mamutik Island, Manukan Island, Sapi Island and Tanjung Aru Beach) to be used in this study. From the finding, the highest identified species were Aspergillus species (27 isolates) followed by Trichoderma species (12 isolates), Penicillium species (10 isolates), Fusarium species (6 isolates), Bipolaris species (1 isolate) and Chaetomium species (1 isolate). ITS fragment of all isolates was amplified in within the size range of 533–658 bp. A phylogenetic tree was constructed using maximum likelihood (ML) method; the isolates were grouped into three clades according to their classes. In conclusion, diverse microfungi isolated from sandy beach soil depicting 19 species were discovered. Future studies are highly recommended to focus on intra- and interspecies diversity based on microsatellite markers analysis, consequently the originality and distribution of the fungal isolates. The outcome of this study includes a baseline data on the occurrence and species-diversity as well as important information on the status of microfungi in Malaysia beaches located in Kedah, Melaka and Sabah. It can be used as a checklist for future studies related to fungi distribution in the tropical beaches.

The presence of microscopic spores in the air affects the quality of air inhaled by animals including humans. Microbial contamination of air impacts the well-being of occupants of an indoor environment, sometimes with dire consequences. The study investigated fungal contaminations of indoor and outdoor air of the Hospital, Library and Senior Common Room (SCR) of the University of Cape Coast, Ghana. Indoor and outdoor air was sampled using the Koch’s sedimentation method. Colony forming units per cubic meter of air (cfu/m3) were determined with the Omeliansky formula. The isolated fungi were identified based on morphological and growth characteristics. For indoor air, the least colony counts were recorded in the SCR for both morning and afternoon samples, whilst the Hospital air had the highest colony counts. For outdoor air, the colony counts were lower in SCR and the Library for both morning and afternoon samples compared to the Hospital. The results further indicated that indoor concentrations of fungi, for morning and afternoon, ranged between 4.0x104 and 2.1x105 cfu/m3, whereas outdoor concentrations of fungi ranged between 1.1x105 and 3.0x105 cfu/m3, revealing an overall higher levels of contamination of outdoor air than indoor air at all the three buildings. Consequently, estimated indoor/outdoor (I/O) concentration ratios of fungi revealed an exogenous source of indoor contaminations at all the three buildings sampled. Fungi isolated from indoor and outdoor air were of the genera Aspergillus, Curvularia, Cylindrocarpon, Fusarium, Mucor, Neurospora, Penicillium and Rhodotorula. We conclude that indoor and outdoor air of the buildings sampled were contaminated with airborne fungi; however, based on estimated I/O ratios, the indoor ambient conditions of the buildings were good. The implication of findings of this study is that the presence of airborne fungal contaminants of indoor and outdoor workplace environment may pose serious occupational health consequences, hence low productivity.
