ABSTRACT
Bacillus subtilis is a good producer of mannanase.This is the first study to investigate mannanase production under solid state fermentation(SSF) by Bacillus subtilis.Bacillus subtilis WY34 was used for the production of extracellular mannanase in the SSF of wheat bran.The highest mannanase activity was 7,650 U/g dry matter when the following conditions were used wheat bran 5g,initial moisture content 71%,Tween-80 1%,konjac powder 0.4 g,initial pH 7.0,incubation temperature 50 ℃.Enzyme production was increased 178% after optimization.
