“…On the other hand, the consortium CS2 was predominated by Enterobacteriaceae ((78:00±26:68) %), followed by Clostridia ((3:6 ± 13:7) %), fungi ((0:07 ± 0:02) %), and other microorganisms ((18:33 ± 7:32) %) (Figure 3). Several microbial consortia-with cellulolytic activity-were isolated and selected from different ecosystems, such as soils, straws and composts (Haruta et al, 2002;Feng et al, 2011;Gao et al, 2014;Young et al, 2018;Da Silva et al, 2019). Moreover, the identification of the cellulolytic consortia-degrading filter papers, newspapers, printing papers and cotton-found a great microbial diversity, including several genera: grampositive bacteria (Brevibacillus and Clostridium), gram-negative bacteria (Enterobacteriaceae, Pseudoxanthomonas), obligate anaerobes (Clostridia, Bordetella, etc.…”
