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:Marburg virus is a genetically simple RNA virus that causes a severe hemorrhagic fever upon infection in humans and non-human primates. The mechanism of how this pathogenesis comes about is not well understood, but it is well accepted that pathogenesis is significantly driven by a hyperactive immune response. To better understand the overall response to Marburg virus challenge, we undertook a transcriptomic analysis of immune cells circulating in the blood following aerosol exposure of cynomolgus macaques to a lethal dose of Marburg virus. Using two-color microarrays, we analyzed the transcriptome of peripheral blood mononuclear cells that were collected throughout the course of infection from 1 to 9 days postexposure, representing the full course of the infection. The host response to aerosolized Marburg was evident at 1 day post-exposure. The response followed a 3-phase response that was led by a robust innate immune response. Analysis of cytokine transcripts that were overexpressed during infection indicated that previously unanalyzed cytokines are likely induced in response to exposure to Marburg virus, and further suggested that the immune response may favor a Th2 response that would hamper the development of an effective antiviral immune response. Late infection events included the upregulation of coagulation associated factors. These findings suggest new avenues for investigating the pathogenesis of Marburg virus infection and provide rich dataset of factors expressed throughout the course of infection that can be investigated as markers of infection and targets for therapy. RNA was isolated from a total of 30 PBMC samples from 15 cynomologus macaques infected with Marburg Virus. Samples were obtained at sequential timepoints post-infection, and included a pre-infection specimen from each animal. These samples were then processed and hybridized onto the Agilent 2-color arrays.
