Overview


  • Bacillus methanolicus is a Gram-positive, spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 48-50%. Bacillus methanolicus is unlikely to be a gut coloniser. (Logan2011Bergey; Arfman1992)



  • This organism has been recovered from soil, wastewater treatment systems and hotsprings. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.

  • QUIRKS
  • Obligate aerobe and high salt required for optimum growth, so likely a gut non-coloniser.

  • Bacillus methanolicus is one of the few described microbial candidates with a potential for the conversion of methanol to value-added products. Its capabilities of producing and secreting the commercially important amino acids l-glutamate and l-lysine to high concentrations. [PMID: 25431011]

  • GutFeeling KnowledgeBase COMMENTS [Website]

    Bacillus methanolicus MGA3 was isolated from freshwater marsh soil and characterised as a thermotolerant and methylotrophic L-glutamate producer. The complete genome consists of a circular chromosome and the two plasmids pBM19 and pBM69. It includes genomic information about C1 metabolism and amino acid biosynthetic pathways.
