In submicroscopic regions of the fiber, the amorphous cellulose is more rapidly attacked than the crystalline. A composite bacterial preparation for decomposing the plant straw or stalk to obtain bacterial fertilizer is prepared from cellulose decomposing bacteria (8-40 vol portions), bacillus (30-50), yeast (10-20) and mould (30-50) through slant culturing, culturing bacterial strains, and preparing the product. <> Never dried bacterial cellulose (4mm thick) membranes were supplied from The mode of action or the mechanism of microbial degradation can only be explained when the enzyme preparations used are homogenous, i.e. Thus, the acceleration of the C cycle was primed by exogenous organic C and was controlled by N. This confirms the stoichiometric decomposition theory. Background Grasshoppers are typical phytophagous pests, and they have large appetites with high utilization of plants fibers, the digestion of which may depend on the microorganisms in their intestines.
