Two mutant strains of Ruminococcus flavefaciens strain 007 that differ in their ability to hydrolyse cotton fibres have been shown also to differ in their cell-surface topology, in that the cotton degrading form possessed larger and more protuberant cell surface structures. The strains had similar CMCase, cellobiosidase and beta-glucosidase activities. The results indicate the importance of cel...

in view of the increase in saccharomyces cerevisiae mannan content, the culture condition for s.cerevisiae were optimized in this study. the influence of culture condition such as original ph, inoculum size, and temperature on mannan production were evaluated using response surface methodology. the mathematical model was established by the quadratic rotary combination design. with the order of ...

Five organic supplements namely cotton seed meal (CSM), peanut meal (PM), wheat bran (WB), rice bran (RB) and soybean meal (SBM) were supplemented to the wheat straw @ 10% and 20% (on dry weight basis). Mycelial growth and enzyme activity of Lentinus edodes strain Le-S were recorded at periodic intervals of 10 d upto 30 d. Maximum mycelial extension rate was obtained with 10% rice bran suppleme...

Use of alkali-pretreated rice straw and untreated rice straw as substrates for enzyme production under solid-state cultivation was investigated. Cellulase produced from untreated rice straw showed higher activity of FPase, CMCase, β-glucosidase, and xylanase at 6.25 U/g substrate, 111.31 U/g substrate, 173.71 U/g substrate, and 433.75 U/g substrate respectively, as compared to 1.72 U/g substrat...
