- Abstract:
- By measuring pH,cellulase activity ,microbialcompositionano theefficiency of corn-stalkdegra-dation, the properties of a composite microbial system in decomposing corn stalk were investigated using batchexperiments. The results indicated that the system pH remained stable at between 6. 5 to 7.5 during the cornstalk degradation. C,enzyme ( β-glucosidase), C,enzyme (endo-β-1 , 4-glucanase) and C, enzyme ( exo-β.1 , 4-glucanase) were, in tumn, into highly active stage with the degradation of corn straw. There was a goodsynergic effeet between them, The number of fungi maintained at a high level. The straw degradation efficiencyhad been a steady increase along with the bacteria amount increasing all the time in the whole process of cornstraw degradation, The results showed that the straw-degradation inocula was stable.
