The potential of fungi as bio degraders of micro plastic particles was assessed using standard microbiological and Fourier transformed Infra-Red (FTIR) spectroscopic analysis methods. The highest mean Total Heterotrophic fungal (THF) count of 4.24x104 cfu/ml was obtained with the least THF (2.72x104 cfu/ml) recorded during the dry season. Mean hydrocarbon Utilizing Fungal (HUF) count was highest (1.78x104 cfu/ml) during the wet period while the least HUF count (1.46x104 cfu/ml) was recorded during the dry period. Spectra of FTIR showed that the water contained microplastic particles in these proportions; polyethylene of low density (LDPE) 0.01%, 0.11% protein, 0.15% polystyrene, 0.37% polyamide, 1.14% cellulose, 1.21% polyurethane, 1.90% polyvinyl chloride, 3.11% polyester and 92% polypropylene, respectively. Species of fungi identified were Aspergillus niger, Penicillium spp., Rhizopus spp., Mucor spp., Aspergillus nidulans, Fusarium spp., Microsporum canis, and Aspergillus fumigatus. Among the fungal isolates, A. niger and A. fumigatus were most active in degrading the micro plastic (polypropylene) with mean % weight loss of 71.09% and 53.09%, respectively while the least active was Penicillium spp. with a mean % weight loss of 28.64% during the study period. The order of degradation was Aspergillus niger > A. fumigatus > A. nidulans > Fusarium spp. > Rhizopus spp. > Microsporum canis > Mucor spp. > Penicillium spp. The potential to degrade micro plastic particles by these fungi can be harnessed. The foremost active fungi degrading potentials are as follows: A. niger (71.1%) and A. fumigatus (53.1%). The study has shown that isolates of fungi from Ohiakwu River in Nigeria possess the ability to degrade micro plastic (polypropylene) particles. Therefore, this research is of tremendous importance for industrial development and additionally for future research purposes.

Feed Samples

The Experiments were carried out during the period of July 2001 to December 2002. Infestation of poultry feeds by fungi and aflatoxins content in feeds were determined. Ten feed samples were collected from ten different farms located in three different areas of Bangladesh. Five different fungal species belonging four genera were detected which were Aspergillus flavus, Aspergillus niger, Fusarium spp, Rhizopus stolonifer and Penicillium spp. Among them Aspergillus flavus and Aspergillus niger were found in all the feed samples and the rest were occasionally found. Effect of storage and moisture content of feeds were studied for determining the influence on occurrence of fungal flora in feeds. Higher the storing period of feed along with higher moisture content resulted superior incidences of fungal population in stored feeds. Studied on storage practice with 4 duration of F1 sample revealed that the presence of aflatoxins were 30.52ppb, 33.36ppb, 37.32ppb and 48.35ppb of 5, 10, 15 and 20 days after production of feeds, respectively.J.

Various herbal teas including German chamomile, Chrysanthemum Vascuflow herb tea, hop, jasmine and orange flowers, sweet marjoram, spearmint and thyme leaves, and papaya-mint tea as well as coffee substitutes (Bambu instant Swiss, Teeccino chocolate-mint, and Teeccino Mediterranean Espresso) were analyzed for fungal contamination and the presence of aerobic mesophilic bacteria (APC). The results of this investigation showed that fungal counts reached levels as high as 5.8 × 105 colony forming units (cfu) per gram. German chamomile harbored the highest fungal contamination. The most common fungi found in herbal teas were Aspergillus niger, Penicillium spp., Eurotium rubrum, E. chevalieri, A. flavus, Fusarium spp., Alternaria alternata, and yeasts. Among the coffee substitutes, only the chocolate-mint coffee was contaminated with low numbers (<1.0 × 103 cfu g-1) of E. rubrum, Ulocladium spp. and Phoma spp., and with yeasts (< 100–6.8 × 103 cfu g-1). Aerobic mesophilic bacteria were recovered from 100% of the herbal tea, chocolate-mint and Mediterranean Espresso, and from 50% of the Bambu instant Swiss coffee samples. The highest APC counts of 1.2 × 107 cfu g-1 were observed in spearmint leaves.

One hundred and twenty five soil samples were collected from five areas in the vicinity of Khairpur city, Sindh, Pakistan and screened for the presence of keratinophilic fungi by using hair bait technique. A total 253 isolates belonged to eight genera and eleven species of keratinophilic fungi were recovered. Maximum number (153/253, 60.5%) of keratinophilic fungi was recovered from farm land and poultry soils. Aspergillus niger was most prevalent species and represented 20.2% of the total number isolated. A. flavus and A. fumigatus were almost equal in their prevalence and represented 11.9 and 11.1%, respectively. Botrytis cinaria comes next constituting 9.9%; followed by Mucor spp. (9.1%) and Chochliobolus lunatus (8.3%). Other species isolated less frequently included Chrysosporum asperatum (5.9%), Fusarium spp. (5.1%), Penicillium spp. (3.1%) and A. wentii (2.4%). The distribution pattern of the different keratinophilic fungi and their significance are discussed.Keywords: Keratinophilic fungi, Prevalence, Keratinase, Hair bait techniqueDOI: http://dx.doi.org/10.3329/bjm.v24i1.1246 Bangladesh J Microbiol, Volume 24, Number 1, June 2007, pp 79

Crude petroleum ether and methanol extracts of different parts of five medicinal plants collected from Terai region, namely, Asparagus racemosus, Catharanthus roseus, Hedychium coronarium, Mimosa pudica and Terminalia chebula were examined for their antimicrobial activity against different pathogenic microorganisms, Staphylococcus aureus, Escherichia coli, Klebsella spp., Salmonella paratyphi, Bacillus subtilis, Aspergillus niger, Fusarium spp. and Penicillium spp. From the obtained growth curves of methanol extract of Terminalia chebula and petroleum ether and methanol extracts of Hedychium coronarium, it can be said these extracts have relatively high bacteriostatic property than other plant extracts. Similarly, the zone of inhibitions observed during antifungal assay by methanol extract of Terminalia chebula against Aspergillus niger, Fusarium spp. and Penicillium spp. are comparable to that of Itraconazole (antifungal drug). It shows that Terminalia chebula has fungistatic property. Phytochemical screening revealed the presence of alkaloids, coumarins, flavonoids, terpenoids, steroids and glycosides.
