Abstract
A gram-negative, aerobic, rod-shaped and non-motile marine bacterium, MEBiC09412T was isolated from tidal flat sediment of the Yeonggwang County, South Korea. The 16S rRNA gene sequence analysis revealed that strain MEBiC09412T showed high similarity with the Marinirhabdus gelatinilytica NH83T (96.5%). Growth was observed at 17-38 °C, at pH 4.0-8.5 and with 0.5-6 % NaCl. The predominant cellular fatty acids were iso-C15:0, iso-C15:1 G, iso-C17:0 3OH and summed feature 3 (C16:1ω6c and/or C16:1ω7c). The DNA G+C contents is 43.1 mol%. The major respiratory quinone is MK-6. Several phenotypic characteristics such as production of indole and Enzyme activities of α-chymotrypsin and α-glucosidase differentiate strain MEBiC09412T from M. gelatinilytica NH83T. On the basis of this polyphasic taxonomic data, strain MEBiC09412T is proposed as Marinirhabdus citreus sp. nov. The type strain is MEBiC09412T.similarity with the Marinirhabdus gelatinilytica NH83T (96.5%). Growth was observed at 17-38 °C, at pH 4.0-8.5 and with 0.5-6 % NaCl.
