A Gram-stain-positive alkali-tolerant and strictly aerobic bacterium, designated strain P16T, was isolated from a marine red alga, Porphyridium cruentum, in the Yellow Sea, Republic of Korea. Cells were motile rods with peritrichous flagella and exhibited catalase and oxidase activities. The optimal growth of strain P16T was observed to occur at 30 °C and pH 8.0 and in the presence of 2.0 % (w/v) NaCl. Menaquinone-7 was identified as the sole respiratory quinone. Strain P16T contained anteiso-C15 : 0, iso-C15 : 0, iso-C14 : 0 and iso-C16 : 0, and diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as major cellular fatty acids and polar lipids, respectively. The G+C content of strain P16T was 40.8 mol%. Strain P16T was most closely related to
