Differential properties of the strain H4XT and related type strains of the genus Pontibacter.

Strains: 1, H4XT; 2, P. korlensis X14-1T; 3, P. actiniarum KMM 6156T; 4, P. xinjiangensis 311-10T; 5, P. saemangeumensis GCM0142T. All data were obtained from this study unless otherwise indicated by asterisks. All strains produce N-acetyl-β-glucosaminidase, naphthol-AS-BI-phosphohydrolase, acid phosphatase, leucinearylamidase, valine arylamidase, esterase lipase (C8), alkaline phosphatase and esterase(C4); all strains are negative for hydrolysis of tyrosine, chitin and cellulose, production of indole and H2S, V-P test, glucose fermentation, and activities of arginine dihydrolase, urease, lysine decarboxilase, ornithine decarboxilase, tryptophane deaminase and α-fucosidase. The strains H4XT, P. korlensis X14-1T, P. actiniarum KMM 6156T and P. xinjiangensis 311-10T are not able to assimilate itaconic acid, acetate, L-serine, salicin, L-fucose, D-sorbitol, propionate, valeric acid, 3-hydroxybenzoic acid, 4-hydroxybenzoic acid and L-proline.+: positive; -: negative; w: weakly positive; nd: not determined.
