a, Sampling site indicating the area covered with sugarcane bagasse and an adjacent area where a bulk control soil sample was taken. SBS, sugarcane bagasse-covered soil. b, The alpha diversity index shows that the sugarcane bagasse-covered soil has reduced microbial diversity compared with the control soil. c, Phylogenetic tree illustrating the relationships between the 124 recovered MAGs. Previously undescribed genomes in the taxonomy are highlighted with purple stars. d, Predicted metabolic pathways, glycoside hydrolases (GHs) and the newly described CelOCE in ‘Candidatus Telluricellulosum braziliensis’, highlighting its potential role in cellulose conversion. GHs with low sequence identity (<30%) to known GHs in the CAZy database (https://www.cazy.org/), or those with activities matching their predicted family but not subfamily, are shown in red. Predicted enzymatic activities consistent with their GH family or subfamily classification are indicated by Enzyme Commission (EC) numbers in parentheses.
