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 of three wild-type strains and one genetically engineered strain in two independent chemostat bioreactor experiments, first, with molecular hydrogen and carbon dioxide, and second, 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. Transcriptomics and proteomics data sets from these steady-state bioreactors, in combination with the implementation of a pan-model that contains combined reactions from all three microbes, allowed us to perform an interspecies comparison. 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 combining fermentation and omics data with genome-scale modeling to reveal knowledge gaps of archaeal metabolisms and the biotechnological potential of Methanothermobacter spp. as production platform hosts.

Project description:In the syntrophic interaction between fermentative bacteria (Pelotomaculum thermopropionicum) and methanogenic archaea (methanogens: Methanothemobacter thermautotrophicus), reducing equivalents (e.g., H2) produced by fermentative bacteria should efficiently be consumed by methanogens in order for the fermentation of volatile fatty acids (VFA, e.g., butyrate, propionate, and acetate) to be thermodynamically feasible. It has been known that physical approximation (e.g., coaggregation) between VFA-fermenting syntrophic bacteria (syntrophs) and hydrogenotrophic methanogens is necessary for efficient H2 transfer between them. Our previous study has shown that, at an early exponential growth phase of syntrophic coculture, cells of Pelotomaculum thermopropionicum (syntroph) were connected to cells of Methanothermobacter thermautotrophicus (methanogen) via unidentified extracellular filamentous appendages, after which they started to coaggregate, suggesting that the filamentous appendages may have been important for their syntrophic interaction. The filamentous appendages seemed to specifically connect these syntrophic partners, since such pairwise connection has been observed neither in single-species cultures (monocultures) nor in mixtures with other microbes. <br> We found that P. thermopropionicum has putative gene clusters for flagellum and pilus, while no extracellular filament gene was identified in the M. thermautotrophicus genome. So we examined transcriptome responses of M. thermautotrophicus to the contact with flagellar filament protein (FliC) and flagellar cap protein (FliD) of P. thermopropionicum.

Project description:Methanothermobacter thermautotrophicus is a model thermophilic hydrogenotrophic methanogen. The life and survival of M. thermautotrophicus is highly influenced by the availability of nutrients and temperature. To learn about adaptation mechanisms evolved by the archaea to cope with drastic temperature shifts, the responses of model M. thermautotrophicus ΔH to temperature were investigated using a quantitative proteomics approach with iTRAQ-LC-MS/MS.

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.
