Fungi involved in the biodegradation of maizecob were isolated and screened for cellulase activity using glucose and carboxylmethyl cellulose as carbon sources. The effect of the carbon sources on cellulase production was determined. Eleven fungi species were isolated which include Rhizopus oryzae, Aspergillus flavus, Mucor racemosus, Aspergillus niger, Penicillium atrovenetum, Penicillium expa...

The hazardous nature of aflatoxins to human and animals necessitate the need for establishment of control measures. The objective of this study was to evaluate the inhibition of growth and aflatoxin production of Aspergillus flavus strain (ATCC 16872) by various essential oils in Yeast Extract Sucrose (YES) growth media at 25°C. Essential oils of basil, fennel, coriander, caraway, peppermint an...

PURPOSE To report the clinical, microbiologic, confocal scan and histopathologic features of Aspergillus flavus keratitis which developed immediately after deep anterior lamellar keratoplasty (DALK). CASE REPORT A 28-year-old woman underwent DALK using the big-bubble technique for keratoconus. The operation was uneventful, yielding a bare Descemet's membrane (DM) followed by transplantation o...

LILLEHOJ I Northern Regional Research Laboratory, Agricultural Research Service, U.S. Department of Agriculture, Peoria, Ill. 61604. 2 Agricultural Research Service, U.S. Department of Agriculture, University of Missouri, Columbia, Mo. 65201. Of the wide array of identified, toxic, fungal metabolites or mycotoxins, the aflatoxins have been studied the most intensively. Expanding research ...

the present study was carried out to investigate the occurrence of total mycobiota and aspergillus species at different stages of fig production and processing in iran. in the meantime, the potential of different culture media for isolation of fungal species from figs was also investigated. the mycobiota of 389 samples of dried fig were studied. total fungal counts ranged from

An Aspergillus parasiticus gene, designated apa-2, was identified as a regulatory gene associated with aflatoxin biosynthesis. The apa-2 gene was cloned on the basis of overproduction of pathway intermediates following transformation of fungal strains with cosmid DNA containing the aflatoxin biosynthetic genes nor-1 and ver-1. Transformation of an O-methylsterigmatocystin-accumulating strain, A...

This study examined the utilization of potato processing wastewater as the feedstock by two oleaginous fungi, Aspergillus flavus I16-3 and Mucor rouxii, for lipid and gamma linolenic acid production. The high strength wastewater contained soluble carbohydrates of 36.2 g/l, soluble chemical oxygen demand (COD) of 40 g/l, total soluble nitrogen of 0.62 g/l, and soluble total phosphorus of 0.24 g/...

We investigated the prevalence of seed borne fungal pathogens in rice variety BRRI Dhan46 and to evaluate the efficacy of antagonistic bacteria in controlling seed borne disease. A composite sample of BRRI Dhan46 was assayed. Five seed borne fungi viz. Fusarium sp., Bipolaris oryzae, Curvularia sp., Gliocladium sp. and Aspergillus flavus were isolated from the rice seeds. Fifteen probable antag...

Aflatoxins are among the most powerful carcinogens in nature. The major aflatoxin-producing fungi are Aspergillus flavus and A. parasiticus. Numerous crops, including peanut, are susceptible to aflatoxin contamination by these fungi. There has been an increased use of RNA interference (RNAi) technology to control phytopathogenic fungi in recent years. In order to develop molecular tools targeti...
