Salt-tolerant cellulose degradation bacterial agent as well as preparation method and application thereof

The invention relates to a salt-tolerant cellulose degradation bacterial agent as well as a preparation method and an application thereof. Active ingredients of the salt-tolerant cellulose degradationbacterial agent comprise any two or three of Bacillus cereus, Pseudomonas stutzeri and Bacillus subtilis. The salt-tolerant cellulose degradation bacterial agent can be applied to biogas slurry containing 0-3% of salt and can express efficient degradability. Research finds that the straw degradation rate is 40%-61% when the straw adding amount is 100-300 g, the adding amount of the salt-tolerantcellulose degradation bacterial agent is 10-30 g and degradation is performed for 15 d in a biogas fermenting process. The composite microbial agent adapts to highly saline and alkaline areas in north, can be applied in an environment with higher salinity of 0-3% and has the characteristics of high straw degradation rate, high biogas yield and the like. 本发明涉及种耐盐纤维素降解菌剂及其制备方法与应用。所述耐盐纤维素降解菌剂的活性成分包括蜡样芽孢杆菌、斯氏假单孢菌、枯草芽孢杆菌中的任两种或三
