Project description:The genome of the lignocellulose-degrading, extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus encodes genes comprising clusters of glycoside hydrolases, ABC transporters and metabolic enzymes that are transcriptionally responsive to carbohydrates. Transcriptomic and biosolubilization analyses were used to determine if C. saccharolyticus could be deployed as a probe to assess the characteristics of plant biomass feedstocks and efficacy of pre-treatment methods, as these both relate to deconstruction strategies for biofuels production. Based on the response of C. saccharolyticus to plant cell wall polysaccharides, genomic loci were identified that reflected the availability of cellulose, glucomannan, pectin and xylan in biomass to microbial degradation. Furthermore, these loci were useful in assessing how various plant biomass feedstocks (genetically and chemically modified Populus sp., unpretreated Populus sp., and chemically modified switchgrass) were amenable C. saccharolyticus solubilization.

Hydrogenomics of the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus

Project description:Caldicellulosiruptor saccharolyticus is an extremely thermophilic, Gram-positive anaerobe, which ferments cellulose-, hemicellulose- and pectin-containing biomass to acetate, CO2 and hydrogen. Its broad substrate range, high hydrogen-producing capacity, and ability to co-utilize glucose and xylose, make this bacterium an attractive candidate for microbial bioenergy production. Glycolytic pathways and an ABC-type sugar transporter were significantly up-regulated during growth on glucose and xylose, indicating that C. saccharolyticus co-ferments these sugars unimpeded by glucose-based catabolite repression. The capacity to simultaneously process and utilize a range of carbohydrates associated with biomass feedstocks represents a highly desirable feature of a lignocellulose-utilizing, biofuel-producing bacterium. Keywords: substrate response
