The use of straw as a carbon source fermentation of cellulose includin g select from the bacteria

the choice of medium

carbon source structure

water content was optimized.By the Aspergillus niger and Trichoderma reesei mixed str ain as the fermentation bacteria

the result shows that:when the straw powder an d wheat bran mixed with 3:1 ratio of co-carbon source

water content was 70% fer mentation output the cellulose activity is the highest

the highest Cx activity was 1568.47 U/g

filter paper activity was 489.3 U/g. To the cellulose under the conditions of production were used Lactobacillus brevis and Rhizopus oryzae for lactic acid fermentation

lactic acid production results: Lactobacillus brevis: 10.8 g/L; Rhizopus oryzae: 9.2 g/L.
