Aspergillus is an important fungal genus used for the fermentation of Asian foods; this genus is referred to as koji mold in Japan and China. A. oryzae, A. sojae, and A. tamari are used in the production of miso and shoyu in Japan, but a comprehensive taxonomic study of Aspergillus isolated from Meju, a fermented soybean starting material for traditional soy sauce and soybean paste in Korea, ha...

A total of seventeen species belonging to thirteen genera of fungi were isolated from soil samples collected from diverse part of city Bareilly during November 2012 to March 2013 at three intervals. The mycoflora were isolated on Yeast powder soluble starch (YpSs) agar added with antibacterial substances streptomycin. Identification and characterization of the mycoflora were made with the help ...

To produce Aspergillus oryzae alkaline protease (Alp) in an osmophilic yeast Zygosaccharomyces rouxii, we constructed an expression plasmid consisting of the Z. rouxii glyceraldehyde-3-phosphate dehydrogenase (GAPDH) promoter, the prepro-Alp cDNA of A. oryzae, the whole sequence of Z. rouxii plasmid pSR1, and the G418 resistant gene. The resulting plasmid, when introduced into Z. rouxii cells, ...

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...

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...

Novel carbasugars derived from cyclohexane-1,2-dicarboxylic acid were synthesized and tested for inhibitory activity towards fungal glycosidases from Aspergillus oryzae and Penicillium canescens. Significant inhibition was observed, which magnitude depended on configuration of substituents.

Fungal species of the genus Aspergillus play significant roles as model organisms in basic research, as "cell factories" for the production of organic acids, pharmaceuticals or industrially important enzymes and as pathogens causing superficial and invasive infections in animals and humans. The release of the genome sequences of several Aspergillus sp. has paved the way for global analyses of p...

Understanding the nature of species" boundaries is a fundamental question in evolutionary biology. The availability of genomes from several species of the genus Aspergillus allows us for the first time to examine the demarcation of fungal species at the whole-genome level. Here, we examine four case studies, two of which involve intraspecific comparisons, whereas the other two deal with intersp...

The present study aimed to ascertain the influence of crude protein (CP) digestibility in the rumen on the quantity and quality of milk production and reproductive performance, blood (BU) and milk (MU) urea, haematological profile and vaginal mucus urea, ammonia and potassium of buffalo cows. Lactating buffaloes (n = 84), 60 days in milk, were randomly subdivided into Group C (control, n = 42) ...

Conidia of domesticated yellow-green aspergilli from strains of Aspergillus oryzae (Ahlburg) Cohn and Aspergillus sojae Sakaguchi and Yamada ex Murakami, used in the preparation of koji inoculum, germinate approximately 3 h sooner than conidia produced by related wild species, Aspergillus flavus Link ex Fr. and Aspergillus parasiticus Speare. There was no consistent relationship between average...
