Abstract 

A Gram-stain-negative, rod-shaped, non-motile and aerobic bacterial strain, designated CHL1T, was isolated from a sludge sample collected from a sewage treatment tank of an agricultural chemical factory. 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.
