RT Journal Article SR Electronic(1) A1 Kelly, D P A1 McDonald, I R A1 Wood, A PYR 2000 T1 Proposal for the reclassification of Thiobacillus novellus as Starkeya novella gen. nov., comb. nov., in the alpha-subclass of the Proteobacteria. JF International Journal of Systematic and Evolutionary Microbiology, VO 50 IS 5 SP 1797 OP 1802 DO https://doi.org/10.1099/00207713-50-5-1797 PB Microbiology Society, SN 1466-5034, AB Thiobacillus novellus is a facultatively chemolithoautotrophic and methylotrophic, Gram-negative, rod-shaped sulfur bacterium, shown by 16S rRNA gene sequence analysis to be a member of the alpha-2 subclass of the Proteobacteria. As such, it must be excluded from the genus Thiobacillus, whose species are members of the beta-Proteobacteria. It closest phylogenetic neighbour appears to be Ancylobacter, from which it is distinct morphologically and in some physiological characteristics. It is distinct physiologically and biochemically in a number of diagnostic features from Paracoccus versutus, in the alpha-3 subclass of the Proteobacteria and does not appear to be sufficiently closely related to any other genus of the alpha-Proteobacteria to be reassigned to a known genus. The new genus and species name Starkeya novella is proposed for T. novellus. The type strain is ATCC 8093T (= NCIMB 10456T = NCIMB 9113T = DSM 506T = IAM 12100T = IFO 12443T = CCM 1077T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-50-5-1797
