ISOLATION AND IDENTIFICATION OF CELLULOSE-DECOMPOSING MIXED STRAIN

A cellulose-decomposing mixed strain was isolated from natural habitats, which contained Klebsiella sp., Pseudomonas sp., Stenotrophomonas sp. identificated by 16S rDNA sequencing. By comparing the relative activity of carboxymethyl cellulose(CMC)enzyme and the effects on decomposing filter paper and banana plant stalks among each single bacteria and the mixed strain, it was shown that each strain had certain capability of decomposing cellulose, but mixed strain behaved the best and the relative activity of CMC enzyme was 0.93 cm/d. It indicated that synergistic effect among several microorganisms would accelerate the decomposition of cellulose materials.
