RNA-seq analysis of methanol-adapted Sporomusa ovata DSM-2662

Project description:Expression profile of wild-type S. ovata and methanol-adapted strain grown autotrophically with H2 as the source of electron. Illumina RNA-Seq of total RNA extracted from a strain of S. ovata evolved by adaptive laboratory evolution to grow faster with methanol 2% as the sole susbtrate and from the wild type. The adapted strain was transfer 18 times on methanol 2%. Total RNA was extracted from both strains growing with H2/CO2.

Pichia angusta cells glucose- vs methanol-grown

Project description:Transcriptional profiling of Pichia angusta NCYC 495 leu1.1 cells growing exponentially on mineral medium containing 0.5% glucose versus a shift for 2 hours to mineral medium containing 0.5% methanol. Two-conditions experiment, 4 individual glucose-grown cultures were shifted at OD660nm 2.3 to fresh mineral medium OD 0.2 containing 0.5% methanol for 2 hours. Transcriptional profiling was performed using total RNA from the glucose-grown cells at the moment of the shift versus cells adapted to methanol for 2 hours.

Converting Escherichia coli to a synthetic methylotroph growing solely on methanol

Project description:Methanol, being electron-rich and derivable from methane or CO2, is a potentially renewable one-carbon (C1) feedstock for microorganisms. Although the ribulose monophosphate (RuMP) cycle used by methylotrophs to assimilate methanol differs from the typical sugar metabolism by only three enzymes, turning a non-methylotrophic organism to a synthetic methylotroph that grows to a high cell density has been challenging. Here, we reprogrammed E. coli using metabolic robustness criteria followed by laboratory evolution to establish a strain that can utilize methanol as the sole carbon source efficiently. This synthetic methylotroph alleviated a heretofore uncharacterized hurdle, DNA-protein crosslinking (DPC), by insertion sequence (IS) mediated copy number variations (CNV) and balanced the metabolic flux by mutations. Being capable of growing at a rate comparable to natural methylotrophs in a wide-range of methanol concentrations, this synthetic methylotrophic strain illustrates genome editing and evolution for microbial tropism changes, and expands the scope of biological C1 conversion.

Comparative transcriptome analysis of a novel obligate Methylomonas sp. DH-1 reveals key differences in the transcriptional responses in C1 and secondary metabolite pathways during growth on methane and methanol

Project description:We integrated genomic and transcriptomic analysis of a newly isolated obligate Methylomonas sp. DH-1 grown on methane and methanol. Comparative transcriptomic analysis between methane and methanol as a sole carbon source revealed different transcriptional responses of Methylomonas sp. DH-1, especially in C1 assimilation, the secondary metabolites pathways and the oxidative stress related genes

Comparative proteomics of Desulfotomaculum kuznetsovii grown on methanol and ethanol

Project description:The aim of this study was to unravel the methanol metabolism of Desulfotomaculum kuznetsovii. Anaerobic methylotrophs, such as methanogens and acetogens, use a pathway initiated by a cobalamine-containing methanol methyltransferase, whereas aerobic methylotrophs generally oxidize methanol to formaldehyde through a pathway initiated by a methanol dehydrogenase. Sulfate-respiring cells grown with methanol in the presence and absence of cobalt and vitamin B12 were analyzed and compared with cells grown with lactate or ethanol. Proteome analysis showed the presence of two methanol degrading pathways in D. kuznetsovii: a cobalt-dependent methanol methyltransferase and a cobalt-independent alcohol dehydrogenase. This is the first time that two methanol pathways have been shown to be present in a single microorganism, and we hypothesize this can give D. kuznetsovii a competitive advantage.

Transcriptome analysis of Beijerinckiaceae RH AL1 under methanol oxidation conditions

Project description:Beijerinckiaceae bacterium RH AL1 was grown exponentially in with methanol (1% [v/v]) as carbon source and lanthanum (1µM) as necessary growth supplement. Harvested biomass was subjected to RNA extraction, mRNA-enrichment and Illumina sequencing library preparation for subsequent RNA-Seq analysis. The scope of this gene expression analysis was to validate the expression of genes linked to pathways that are involved in C1-metabolism.
