C. saccharolyticus transcriptomes reveal consequences of chemical pre-treatment and genetic modification of lignocellulose

(Submitter supplied) 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. more...

Comparative analysis of extremely thermophilic Caldicellulosiruptor species reveals common and differentiating cellular strategies for plant biomass utilization

(Submitter supplied) Microbiological, genomic and transcriptomic analyses were used to examine three species from the bacterial genus Caldicellulosiruptor with respect to their capacity to convert the carbohydrate content of lignocellulosic biomass at 70°C to simple sugars, acetate, lactate, CO2 and H2. C. bescii, C. kronotskyensis and C. saccharolyticus solubilized 38%, 36% and 29% (by weight) of unpretreated switchgrass (5 g/l), repectively, which was about half of the concentration of crystalline cellulose (Avicel, 5 g/l) that was solubilized under the same conditions. more...

Transcriptional analysis of the response of Caldicellulosiruptor saccharolyticus to different H2 partial pressures

(Submitter supplied) Caldicellulosiruptor saccharolyticus is an extremely thermophilic, gram-positive anaerobe which ferments a broad range of substrates to mainly acetate, CO2, and hydrogen gas (H2). Its high hydrogen-producing capacity make this bacterium an attractive candidate for microbial biohydrogen production. However, increased H2 levels tend to inhibit hydrogen formation and leads to the formation of other reduced end products like lactate and ethanol. more...

Phylogenetic, microbiological and glycoside hydrolase diversities within the extremely thermophilic, plant biomass-degrading genus Caldicellulosiruptor

(Submitter supplied) Phylogenetic, microbiological and comparative genomic analysis was used to examine the diversity among members of the genus Caldicellulosiruptor with an eye towards the capacity of these extremely thermophilic bacteria for degrading the complex carbohydrate content of plant biomass. Seven species from this genus (C. saccharolyticus, C. bescii (formerly Anaerocellum thermophilum), C. hydrothermalis, C. more...

Lignocellulosic biomass deconstruction by the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus

(Submitter supplied) The ideal microorganism for consolidated biomass processing to biofuels has the ability to breakdown of lignocellulose. This issue was examined for the H2-producing, extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus growing on lignocellulose samples as well as model hemicellulose components. Identification of the enzymes utilized by the cell in lignocellulose saccharification was done using whole-genome transcriptional response analysis and comparative genomics.

Csac growth on model substrates found in lignocellulose

(Submitter supplied) The co-utilization of hexoses and pentoses derived from lignocellulose is an attractive trait for in microorganisms considered for consolidated biomass processing to biofuels. This issue was examined for the H2-producing, extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus growing on oligosaccharides (composed of glucose and xylose) compared to monosaccharides. Based on the whole-genome transcriptional response analysis and comparative genomics, carbohydrate specificities for transport systems could be proposed for a number of the 24 putative carbohydrate ATP-binding cassette (ABC) transporters in the C. more...

Hydrogenomics of the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus

(Submitter supplied) 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. more...

NCSU_Caldicellulosiruptor saccharolyticus_3K array_version 1

(Submitter supplied) A DNA microarray was designed and constructed based on 2793 protein-coding sequences in the C. saccharolyticus genome obtained from the Department on Energy's Joint Genomes Institute (http://genome.ornl.gov/microbial/csac). OligoArray 2.0 (Rouillard, 2003) was used to generate one 60-mer oligonucleotide probe sequence for each open reading frame. The probes were synthesized (Integrated DNA Technologies, IA), re-suspended in 50% DMSO, and printed onto Ultragap microarray slides (Corning, NY) using a QArrayMini arrayer (Genetix, UK). more...
