Lignocellulosic biomass deconstruction by the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus

Project description: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.

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

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.

Transcriptional profiling of biomass degradation-related genes during Herbivorax saccincola A7 growth on different carbon sources

Project description:Herbivorax saccincola A7 is an alkali-thermophilic lignocellulolytic bacterium that was known to possess a strong xylan degradation ability. They can utilize a wide range of carbon sources, however the response and regulation mechanisms to different carbon sources, in terms of genes expression, are still not identified. In this study, H. saccincola A7 was cultured with cellobiose, cellulose, xylan, cellulose-xylan mixture, and empty fruit bunch (EFB) as the sole carbon source. We carried out a comparative expression analysis, focusing on biomass degradation-related genes. The cellulosomal scaffolding proteins and cellulosomal enzymes of H. saccincola A7 were drastically induced when a cellulose-containing substrate was used as a carbon source. On the other hand, xylan induced only some non-cellulosomal enzymes that might be necessary for xylan degradation. The identification of the carbohydrate-sensing mechanism in H. saccincola A7 appeared a similar system as previously described in Clostridium thermocellum. The lignocellulose degradation ability of H. saccincola A7 may be controlled enzyme expression by cellulose-containing substrate, not by xylan. Thus, recognition in the existence of cellulosic substrates is effective in enhancing a high xylan degradation ability in H. saccincola A7.

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.

Xylan utilization by haloarchaea-nanohaloarchaea associations

Project description:In hypersaline brines, biodegradation of recalcitrant plant polymers can be inhibited by salt-induced microbial stress and/or caused by inadequate metabolic capabilities of extremely halophilic microbes. Therefore, woody materials can be well-preserved even in NaCl brines that are less biologically hostile than most other brines. Here, we considered whether the nanohaloarchaea, that live alongside (the related) haloarchaea, ever partake in the degradation of xylan, a major hemicellulose component of wood. Samples were taken from natural evaporitic brines and anthropogenic solar salterns located in various parts of Europe and Asia. We recently demonstrated that nanohaloarchaeon Ca. Nanohalobium constans lives as an ectosymbiont associated with the chitinolytic haloarchaeon Halomicrobium. Here, we describe an extremely halophilic xylan-degrading consortium with three members, where nanohaloarchaea act as ectosymbionts of Haloferax lucertensis, which in turn acts as a scavenger of xylan-degradation products, produced by a primary xylan hydrolytic Halorhabdus species. The two corresponding binary associations of nanohaloarchaea, Candidatus Nanohalococcus occultus SVXNc and Candidatus Nanohalovita haloferacivicina BNXNv and their hosts were obtained, stably cultivated and characterized. In contrast to the previously described association of chitinolytic haloarchaeon Halomicrobium and its amylolytic symbiont Ca. Nanohalobium, the host haloarchaea within the xylan-degrading consortium could metabolize α-glucans (glycogen and starch), and, thus, obtained no obvious trophic benefit from ectosymbionts. The current study has broadened the range of culturable ectosymbiontic nanohaloarchaea and demonstrates that they are an important ecophysiological component of polysaccharide-degrading halophilic microbial communities and can be readily isolated in binary co-cultures by using the appropriate enrichment strategy.
