Cellulose and its associated polymers are structural components of the plant cell
wall, constituting one of the major sources of carbon and energy in nature. The
carbon cycle is dependent on cellulose- and lignin-decomposing microbial
communities and their enzymatic systems acting as consortia. These microbial
consortia are under constant exploration for their potential biotechnological
use. Herein, we describe the characterization of the genome of Dyella
jiangningensis FCAV SCS01, recovered from the metagenome of a
lignocellulose-degrading microbial consortium, which was isolated from a
sugarcane crop soil under mechanical harvesting and covered by decomposing
straw. The 4.7 Mbp genome encodes 4,194 proteins, including 36 glycoside
hydrolases (GH), supporting the hypothesis that this bacterium may contribute to
lignocellulose decomposition. Comparative analysis among fully sequenced
Dyella species indicate that the genome synteny is not
conserved, and that D. jiangningensis FCAV SCS01 carries 372
unique genes, including an alpha-glucosidase and maltodextrin glucosidase coding
genes, and other potential biomass degradation related genes. Additional genomic
features, such as prophage-like, genomic islands and putative new biosynthetic
clusters were also uncovered. Overall, D. jiangningensis FCAV
SCS01 represents the first South American Dyella genome
sequenced and shows an exclusive feature among its genus, related to biomass
degradation.
