In order to screen out the microflora for rapidly decomposing the agricultural solid wastes such as maize straw,5 types of initial bacterial flora separated from livestock manure and fermented straw were used to collocate with each other for finding out the highly efficient and stable microflora.In which,CDS-10 was screened out by subculture and its degradation ability and enzymatic vigour were tested.The results showed that along with the increment of culture algebra the degradation ability of CDS-10 was gradually increasing and stabilizing,and decomposition rate was 63.09% when it reproduce to the 30th generation;The enzymic vigour of exoglucanase,endoglucanase and filter paper enzyme tended to be stable since the 30th generation.The exoglucanase vigour significantly increased to 11.63 U/mL;the content of the cellulose,hemicellulose and lignin in maize straw was decreased to certain degrees,among them,the degradation rate of hemicellulose was the highest (92%).This suggested that CDS-10 performed a stable and efficient ability to decompose ingredient of maize straw especially hemicellulose under the favorable conditions,and exoglucanase was the main enzyme to influence the degradation effect.CDS-10 showed a promising future in terms of straw resource utilization.
