= Methylobacterium organophilum
{c}
<Methylobacterium organophilum> is a <species> of <bacteria> and the <type species> of <Methylobacterium>. Its reference strain is maintained under collection identifiers including ATCC27886, DSM18172 and NBRC15689. These codes identify deposits of the reference material, rather than three different species.<Methylobacterium organophilum in LPSN>[Species record, type-strain field and genus-type note]{ref}
The organism provides a concrete example of why provenance matters in <genome> comparisons. A 2021 comparative study newly sequenced the NBRC15689 reference strain because an existing assembly attributed to an older deposit, DSM760, did not reliably represent the intended taxon. LPSN identifies DSM760 as <Methylobacterium radiotolerans>.<Comprehensive Comparative Genomics and Phenotyping of Methylobacterium Species by Ola Alessa and others>[Materials and Methods, Genome Sequencing: rationale for replacement organophilum sequence]{ref}<Methylobacterium organophilum in LPSN>[Note on DSM760]{ref} An internally well-assembled sequence can therefore still answer the wrong biological question if its source organism is misidentified.
For a comparison example, imagine two reports carrying the same species label, one based on the intended reference culture and one on a misassigned culture. A difference in <gene> content could arise from the identity mismatch rather than from ordinary variation within the species. Resolving the strain's collection code and biological identity must precede that interpretation. The lesson links naming, preserved cultures and sequence measurements: each supplies information needed to make the others scientifically reusable.
