Low-temperature-resistant bacillus subtilis and application thereof

The invention belongs to the field of microorganisms, and particularly relates to low-temperature-resistant bacillus subtilis and application thereof. According to the technical scheme, the bacillus subtilis N3-3 is preserved in the Guangdong Microbial Culture Collection Center on December 12, 2022, and the preservation number is GDMCC (China General Microbiological Culture Collection Center) NO: 62537. The invention provides a novel cellulose degrading bacterium which can keep good activity and cellulose degrading capability under a cold condition. The microorganism composition is provided based on the microorganism, all microorganisms in the composition play a synergistic effect, and the degradation capacity on all organic matter under the cold condition can be further improved. 本发明属于微生物领域，具体涉及一株耐低温的枯草芽孢杆菌及其应用。技术方案为：一株枯草芽孢杆菌(Bacillus subtilis)N3-3，于2022年12月12日保藏于广东省微生物菌种保藏中心，保藏编号为：GDMCC NO：62537。本发明提供了一株新的纤维素降解菌，在寒冷条件下也能保持良好的活性和纤维素降解能力。并基于该微生物提供了微生物组合物，组合物中各微生物相互之间发挥协同作用，可进一步提升寒冷条件下对各项有机物的降解能力。
