- Abstract:
- Straw returning to farmland directly has negative effects on seed germination and crop growth．Adding high—efficient cellulose—decomposing bacteria is an effective method to resolve this problem．Fivestrains with different cellulase composition were isolated from rotten straw，COW dung compost，and paddy soil．One of the five strains which named X1 had the maximum cellulage activity and the optimal cellulase composi．tion．In this study the Cx，Cb，C1and FPA of X1 were 53．6 U／mL、69．7 U／mL、9．5 U／mL and 11．6 U／mL，and the straw degradation efficiency was up to 40．20％．The degradation efficiency of the combination ofstrains X1 and X2 Wag up to 45．50％，which higher than the others combination strains．According to themorphological characteristics of X1 and X2，it was deduced that they were Penicillium．
