Straw-degrading Bacillus cereus BJ-2 and preparation method of Bacillus cereus BJ-2 agent

This lignin-degrading bacterium is a strsolated from cow dung through enrichment culture, possessing strong lignin degradation capability; the strain grows using cow dung as the sole nitrogen source, and its biomass activity is increased and lignin degradaity enhanced through cow dung induction in liquid culture. The preparation method of this microbial agent is simple and low-cost, and it is convenient to apply by broadcasting on the soil; its degradatiofficiency in the soil can reach 63.2%, and it can also be used as a microbial fertilizer, offering promising application prospects.
