两组纤维素分解菌复合系MC-A1和MC-N1的筛选及其协同功能初探
Selection and cooperative functionality of two groups of cellulose degrading microbial communities MC-A1 and MC-N1 with different degradation effects
摘要
Abstract
We screen two groups of composite microbial systems, MC-A1 and MC-N1, with stronger cellulose degrading capabilities from homemade compost heap and several natural fermentation materials by regular regeneration during incubation. MC-At is a composite thermophilic aerobic cellulolytic microbial community which is acquired by a subculture technique of shake-flask-fermentation broth, while MC-N1 is another composite microbial community with thermophilic anaerobic cellulolytic capability which is obtained by static cultivation and regular regeneration. It is discovered that the degradation rates of communities MC-A1 and MC-N1 for wheat-straw powder can reach 42％ and 38％ within 96 h. Their quickest degradation rates occur between 48 h and 06 h, but these rates steeply decline after 96 h. This degradation rate can reach 47％ by incubation of MC-A1 through 96 h shake-flask-fermentation and then incubation of MC-N1 through 96 h static cultivation. This demonstrates that these two cellulolytic microbial communities show cooperative function in the course of the degradation of non-natural cellulose.关键词
