Growth was observed at 17–38 °C (optimum 30 °C), at pH 4.0–8.5 (optimum pH 7.0) and with 0.5–6.0 % (w/v; optimum 2.5 %) NaCl. The predominant cellular fatty acids were iso-C15 : 0 (27.4 %), iso-C15 : 1 G (9.6 %), anteiso-C15 : 0 (14.6 %), iso-C16 : 0 (6.2 %), iso-C17 : 0 3OH (13.2 %) and summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 7.4 %). The DNA G+C content was determined to be 43.1 mol%, while the major respiratory quinone was menaquinone-6. Several phenotypic characteristics such as indole production, the oxidizing patterns of several carbohydrtaes (of glucose, fructose, sucrose, maltose, mannose etc.) and organic acids, and the enzyme activities of α-chymotrypsin and α-glucosidase differentiated strain MEBiC09412T from M. gelatinilytica NH83T. On the basis of this polyphasic taxonomic data, strain MEBiC09412T should be classified as a novel species of the genus Marinirhabdus with the suggested name Marinirhabdus citrea sp. nov. The type strain is MEBiC09412T (=KCCM 43216T=JCM 31588T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002539
