A mycelial extract ofTrichoderma reesei (P-12) was separated into four fractions by high performance liquid chromatography (HPLC). Out of these, two were found to exhibit antifungal activity when tested against plant pathogenic fungi. The level of antifungal compounds was higher in media containing glucose as the carbon source as compared to one containing… (More)
In Trichoderma reesei, QM 9414, β-glucosidase can be selectively induced by xylan. At a concentration of 0.5% xylan in the growth medium, the yield of β-glucosidase is 3 times more than in cellulose medium suggesting that the synthesis of this enzyme in this organism is under an independent regulatory control.
Two effective strains of green gram rhizobia S24 (slow growing and Hup+) and M11 (fast growing and Hup-) were tested for leghemoglobin production in nodules and effectivity on six species of ‘cow pea miscellany hosts’. Both strains nodulate green gram [Vigna radiata (L.) (Wilczek)], black gram [Vigna mungo (L.) (Hepper)], cow pea [Vigna unguiqulata (L.)],… (More)
Yeasts are known to differ widely in the rate of ethanol production (Rose, 1976). Recently, we have reported the identification of slow and fast fermenting yeast strains and some major differences in the level of some key enzymes (Sharma and Tauro, 1968a). It was found that a fast ethanolproducing yeast strain has higher levels of pyruvate 0ecartx)xylase… (More)
The pattern of release of extracellular cellulase during the germination ofTrichoderma reesei spores has been examined. The four enzymes namely, filter paper degrading enzyme, Β-1,4 endoglucanase, Β-glucosidase and xylanase appear sequentially in the culture broth during germination of the spores. The order of enzyme appearance is not altered by the type of… (More)
The ability to retain hydrogen sulfide (H2S) inSaccharomyces cerevisiae is under nuclear gene control. Mutants with the ability to retain greater amounts of H2S than the parent have been isolated and characterised.
