Abstract:
A Gram-negative, short-rod-shaped and non-motile bacterium, strain 12C11 T , was isolated from an oil-degrading consortium, enriched from the Fugong mangrove sediment, Fujian Province of China. Optimum growth was observed at 25 °C, at pH 7.5 and with 4 % (w/v) NaCl. Comparative 16S rRNA gene sequence analysis demonstrated that it shared highest similarity with members of the genus Algoriphagus (97.5–93.4 %), exhibiting 97.5 % sequence similarity to Algoriphagus ornithinivorans IMSNU 14014 T , followed by Algoriphagus vanfongensis KMM 6241 T (97.2 %); it shared 〈 96.0 % sequence similarity with other members of the genus. Levels of nucleotide sequence similarity between gyrB (DNA gyrase subunit B) genes of strain 12C11 T and A. vanfongensis KMM 6241 T , A. ornithinivorans IMSNU 14014 T , Algoriphagus marincola SW-2 T and Algoriphagus hitonicola 7-UAH T were 78.8, 78.6, 75.6 and 77.4 %, respectively. Phylogenetic trees based on these housekeeping genes showed that strain 12C11 T and other Algoriphagus strains formed a distinct lineage. The dominant fatty acids were iso-C 15 : 0 (32.1 %), C 16 : 1 ω7 c /C 16 : 1 ω6 c (11.6 %), iso-C 17 : 1 I/anteiso-C 17 : 1 B (10.1 %), iso-C 17 : 0 3-OH (9.2 %) and iso-C 17 : 1 ω9 c /C 16 : 0 10-methyl (7.1 %), which accounted for 70.0 % of the total fatty acids. DNA–DNA hybridization showed that strain 12C11 T shared low DNA–DNA relatedness with A. vanfongensis KMM 6241 T and A. ornithinivorans IMSNU 14014 T (30.7±0.9 and 30.5±1.8 %, respectively). The G+C content of the chromosomal DNA of strain 12C11 T was 38.4 mol%. The major respiratory quinones were MK-7 (96.0 %) and MK-6 (4.0 %). According to its morphology, physiology, fatty acid composition and 16S rRNA gene sequence data, the novel strain most appropriately belongs to the genus Algoriphagus , but can readily be distinguished from known Algoriphagus species. The name Algoriphagus zhangzhouensis sp. nov. is proposed (type strain 12C11 T = CGMCC 1.11027 T = MCCC 1F01099 T = DSM 25035 T ).
