anaerobic co-fermentation of straw and swine manure. biogas co-fermentation

The spatial and temporal dynamics of microbial community in the straw and sludge, and their correlations to bioreactor performance remain to be unveiled. To address these questions, we investigated the microbial compositions and the dynamics of microbiota associated to straw and sludge during co-fermentation of straw and swine manure using 16S rRNA amplicon pyrosequencing technique. There are 17 samples in total, including 9 and 8 associated with straw and sludge, respectively. each of straw or sludge associated samples includes 3 sampling time point representing different fermentation process.
