Abstract: Lignocellulose is a difficult component in the degradation process of plant straw, and the best method of straw degradation is bio-degradation.The degradation process of straw is complicated and its degradation efficiency is affected by many factors.Therefore, the research on lignocellulosic degrading bacteria was reviewed.The existing problems in the research of degrading bacteria were expounded, and the research on the degradation of actinomycetes and the synergistic effect of other degrading bacteria should be added in the research of degrading bacteria, as well as the influence of the dynamic change of the heap environment on the degradation ability of the compound microbial agent in straw compost.
