Abstract
Two Gram-stain-positive, facultatively aerobic, non-motile and rod- to coccoid-shaped bacterial strains, 23H37-10T and 4HC-13, were isolated from the faeces of greater white-fronted geese (Anser albifrons) at Poyang Lake, Jiangxi Province, PR China. Optimal growth was observed at 35-37 °C, pH 7.0-8.0 and with 0.5-1.5 % (w/v) NaCl. The 16S rRNA gene sequences of strains 23H37-10T and 4HC-13 were identical. Phylogenetic and phylogenomic analyses indicated that strains 23H37-10T and 4HC-13 formed an independent cluster within the genus Corynebacterium and showed 98.8, 97.4, 97.4 and 97.2 % 16S rRNA gene sequence similarity to Corynebacterium urogenitale LMM 1652T, Corynebacterium urealyticum DSM 7109T, Corynebacterium falsenii DSM 44353T and Corynebacterium jeikeium NCTC 11913T, respectively. Cells contained C18 :1 ω9c, C18 : 0 and C16 : 0 as the major cellular fatty acids and MK-9 (H2) as the predominant respiratory quinone. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidyl inositol mannosides, two unidentified phospholipids, four unidentified glycolipids and one unidentified lipid. Strain 23H37-10T contained mycolic acids, with meso-diaminopimelic acid and arabinose as the major whole-cell hydrolysates. The genome G+C content of strains 23H37-10T and 4HC-13 was 55.2 mol%. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strains 23H37-10T and 4HC-13 were 94.4 and 99.6 %, respectively. Strains 23H37-10T and 4HC-13 had dDDH and ANI values of less than 70 and 96 % with all available genomes of the genus Corynebacterium, respectively. The differential genotypic inferences, together with phenotypic and biochemical characteristics, suggested that strains 23H37-10T and 4HC-13 represent a novel species within the genus Corynebacterium, for which the name Corynebacterium anserum sp. nov. is proposed. The type strain is 23H37-10T (=GDMCC 1.1737T=KACC 21672T).
