Comparative metagenomic discovery of the dynamic cellulose-degrading process from a synergistic cellulolytic microbiota

To reveal the dynamic process of cellulose biodegradation and explore more potential cellulases, a microbiota (FPDM) with cellulose-degrading ability was cultivated, different stages filter paper degradation were compared. Ion chromatography comparative metagenomic sequencing revealed that diversity FPDM enhanced as hydrolysate length increased. Sporocytophaga Cohnella dynamically dominated synergistic in early-intermediate intermediate-final periods, respectively. Moreover, 363 declining shifting 231 progressive unannotated genes speculated to participate catabolism cellodextrin/cello-oligosaccharide cellobiose, Based on changes hydrolysates, community structure gene abundance, pathway predicted. Our work should provide new perspective for subsequent identification key cellulolytic strains enzymes clarification mechanism biodegradation.
