摘要:
采用分批实验,通过对玉米秸秆降解过程中的pH、纤维素酶活性、微生物组成及秸秆降解率的检测,考察了复合菌系对玉米秸秆的降解特性.结果表明,在整个降解过程中,体系的pH处于6.5 ～7.5之间,基本保持稳定；Cb酶(β-葡萄糖苷酶)、Cx酶(内切β-1,4-葡聚糖酶)及C1酶(外切β-1,4-葡聚糖酶)随着秸秆的降解,依次进入高活性阶段,呈现出一定的协同性.真菌数量保持较高水平,细菌数量一直稳步上升,秸秆降解率在整个降解过程中也一直稳步上升.说明复合菌系具有一定的稳定性.
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.
