The strain grew at salinities of 0.5–5 % (w/v) NaCl (optimum 2.5 %). Growth occurred at pH 6.0–8.0 (optimum pH 7.0) and 5–40 °C (optimum 28–30 °C). The genomic DNA G+C content was determined to be 70.4 mol%. Q-10 was detected as the respiratory quinone. The major fatty acids (>10 %) were C18 : 1ω7c and/or C18 : 1ω6c and C16 : 0. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, two unidentified phospholipids and two unidentified aminophospholipids. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain CHL1T formed a distinct clade with Albibacter methylovorans DSM 22840T and Methylopila helvetica DM9T within the family Methylocystaceae . On the basis of phenotypic, chemotaxonomic and phylogenetic characteristics, the strain merits recognition as a representative of a novel species of a new genus within the family Methylocystaceae , for which the name Chenggangzhangella methanolivorans gen. nov., sp. nov. is proposed. The type strain of the type species is CHL1T (=KCTC 42661T=CCTCC AB 2015175T). In addition, the species Methylopila helvetica Doronina et al. (2000) is proposed to be transferred to the genus Albibacter as Albibacterhelveticus comb. nov. (type strain DM9T=CIP 106788=VKM B-2189) on the basis of the phylogenetic analysis. An emended description of the genus Albibacter is also provided., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001062
