= Methylobacterium radiotolerans
{c}
<Methylobacterium radiotolerans> is a <species> of <bacteria> within <Methylobacterium>. Its <type strain> has deposits including DSM1819, ATCC27329 and JCM2831. The organism was originally named `Pseudomonas radiora`; the accepted combination and corrected epithet place it in <Methylobacterium>. The epithet refers to tolerating radiation.<Methylobacterium radiotolerans in LPSN>[Name, basonym, etymology and type-strain fields]{ref}
A radiation-related name does not itself supply a survival curve. In an invented measurement, suppose a specified exposure leaves $2\times10^5$ recoverable <colony-forming units> from an initially comparable $10^6$. The measured fraction is $2\times10^5/10^6=0.2$, or 20 percent. Comparing organisms requires a stated <bacterial strain>, exposure and recovery readout; a single species adjective cannot fix those conditions or identify a universal resistance threshold. These numbers illustrate the measurement, not observed values for this species.
Reference-culture identity also matters when interpreting molecular data. LPSN notes that the older deposit DSM760, once associated with <Methylobacterium organophilum>, represents <Methylobacterium radiotolerans>.<Methylobacterium organophilum in LPSN>[Note identifying DSM760]{ref} A genome comparison based on an incorrect label could therefore attribute between-species differences to variation within one species. The name, maintained strain and measured phenotype are complementary pieces of a reproducible record.
