[Biodegradation of lignin in wheat straw by alkaliphilic ligninolytic bacteria with compounded carbons].
The article researched enzymes production, the degradation rate of lignin and strain growth of alkaliphilic ligninolytic bacteria strain No. 6 in alkaline liquid medium (pH approximately 10.5) with compounded carbons. The results showed that the highest activities of laccase and MnP were 2915.37 U/L (4th d) and 1152.88 U/L (8th d), respectively, and the strain degraded 49.84% lignin of wheat straw during ten days cultivation. The changes of ultrastructure of wheat straw caused by strain No. 6 attack were investigated with SEM (scan electron microscopy).
