The DNA G+C contents of the novel isolates (58.5–60.2 mol%) were clearly distinguished from those of L. taeanensis G5T (47.1 mol%) and H. balneolensis DSM 19091T (47.9 mol%). The G+C content of L. taeanensis G5T obtained in this study was quite different from a previous report (63.6 mol%). DNA–DNA hybridization experiments showed that the novel strains constituted a single species. Eleven phenotypic features of the three isolates differed from those of both related genera. The predominant respiratory quinone was ubiquinone-10 and the major fatty acid was C18 : 1ω7c. On the basis of this polyphasic taxonomic analysis, the novel strains represent a novel genus and species, for which the name Algimonas porphyrae gen. nov., sp. nov. is proposed. The type strain of Algimonas porphyrae is 0C-2-2T ( = LMG 26424T  = NBRC 108216T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.040485-0
