Project description:We investigate photorespiration pathways in the chemoautotroph Cupriavidus necator H16 when growing autotropically on hydrogen and carbon dioxide via the Calvin Cycle. We demonstrate an upregulation of the glycerate pathway under photorespiration (ambient carbon dioxide) conditions

Project description:Transcriptomic analysis of C. jejuni HPC5 grown in anaerobic jar supplemented with air mix and in Modular Atmospheric Controlled System (MAC). C. jejuni HPC5 is a Campylobacter strain isolated from broiler chickens. Majority of the Campylobacter strains are cultured in an atmosphere containing 5-10% (v/v) oxygen or 5% hydrogen and 5-10% (v/v) carbon dioxide and the rest with nitrogen. To set up a jar (3.5L, Oxoid) to the required microaerophilic conditions, a vacuum is created to -22 psi and then air mixture of 85% v/v nitrogen, 10% v/v carbon dioxide and 5% v/v hydrogen (Air Products, Crewe, UK) is introduced into the jar. This resulted in a microaerobic atmosphere containing approximately 5.6% oxygen, 3.6% hydrogen, 7.3% carbon dioxide and 83% nitrogen. The Modular Atmospheric Controlled System (MAC; Don Whitely Scientific) is an anaerobic chamber where air mixture of 85% nitrogen, 10% carbon dioxide and 5% oxygen is used for growing Campylobacter. Differences in growth pattern were observed when Campylobacters were grown in it and transcriptomic analysis was done to prove the difference in the regulation of genes in the two conditions.

Project description:Methanococcus maripaludis is a methanogenic Archaea that conserves energy from molecular hydrogen to reduce carbon dioxide to methane. Chemostat grown cultures limited for phosphate or leucine were compared to determine the regulatory response to leucine limitation.

Project description:Methanococcus maripaludis is a methanogenic Archaea that conserves energy from molecular hydrogen to reduce carbon dioxide to methane. Chemostat grown cultures limited for hydrogen, phosphate, or leucine were compared to determine the regulatory response to hydrogen limitation. This was done by comparing hydrogen limited cultures to both leucine limited and phosphate limited cultures. Slow and rapid growing samples limited for either hydrogen or phosphate were compared to determine the regulatory effects of growth rate. Keywords: archaea, hydrogen, leucine, phosphate, nutrient limitation, growth rate, methanogen

Differences in growth pattern were observed when Campylobacters were grown in it and transcriptomic analysis was done to prove the difference in the regulation of genes in the two conditions. There are three biological replicates for each experiment. Seven independent cDNA preps of C. jejuni HPC5 were prepared and they were labelled independently using AF555 (Fisher, UK). The labelled cDNAs were mixed together and this acted as the control. C. jejuni HPC5 was grown both in the Jar and in the MAC and their cDNAs were labelled independently with AF645 (Fisher, UK). Hybridisations were done between C. jejuni HPC5 grown in jar and in MAC in triplicates. The supplementary file (linked at the foot of this record) represents the averaged normalised values for each experimental condition (3replicates/experimental condition).

Project description:Methanogenesis allows methanogenic archaea (methanogens) to generate cellular energy for their growth while producing methane. Hydrogenotrophic methanogens thrive on carbon dioxide and molecular hydrogen as sole carbon and energy sources. Thermophilic and hydrogenotrophic Methanothermobacter spp. have been recognized as robust biocatalysts for a circular carbon economy and are now applied in power-to-gas technology. Here, we generated the first manually curated genome-scale metabolic reconstruction for three Methanothermobacter spp.. We investigated differences in growth performance and gas consumption/production of three wild-type strains and one genetically engineered strain in two independent quadruplicate chemostat bioreactor experiments: 1) with molecular hydrogen and carbon dioxide; and 2) with sodium formate. In the first experiment, we found the highest methane production rate for Methanothermobacter thermautotrophicus ΔH, while Methanothermobacter marburgensis Marburg reached the highest biomass growth rate. We collected statistically reliable transcriptomics and proteomics data sets from these steady-state bioreactors, which we integrated within our genome-scale metabolic models. The implementation of an pan-model that contains combined reactions from all three microbes allowed us to perform an interspecies comparison of the complete omics data set. While the observed differences in the growth behavior cannot be fully explained, the comparison enabled us to identify crucial differences in growth-related pathways, such as formate anabolism. In the second experiment, we found stable growth with a M. thermautotrophicus ΔH plasmid-carrying strain on formate with similar performance parameters compared to wild-type Methanothermobacter thermautotrophicus Z-245. The results of the two studies demonstrate the advantages of an integrative approach using fermentation and omics data with genome-scale modeling for the investigation of lesser studied metabolisms, and the biotechnological potential of Methanothermobacter spp. as production platform hosts.
