A non-pigmented, motile, Gram-negative bacterium, strain Z 271T, was isolated from the surface of leaves of the seagrass Zostera marina which was collected in Troitza Bay (Sea of Japan, Pacific Ocean). The new isolate grew between 5 °C and 28 °C and was slightly halophilic, tolerating environments containing up to 5 % (w/v) NaCl. Strain Z 271T was able to degrade Tweens 20, 40 and 80 and partially degrade gelatin, but was unable to degrade casein. Phosphatidylethanolamine (36.9 %) and phosphatidylglycerol (63.1 %) were the predominant phospholipids. The major fatty acids included C18: 1{omega}7c (43.7 %), C16: 1{omega}7c (31.1 %) and C16: 0 (16.8 %). The main respiratory quinone was Q-8. The DNA–DNA relatedness value of strain Z 271T with Granulosicoccus antarcticus IMCC3135T was 35 %. The G+C content of the DNA of strain Z 271T was 60.2 mol%. On the basis of phenotypic and genotypic characteristics and 16S rRNA gene sequence analysis, strain Z 271T represents a novel species of the genus Granulosicoccus for which the name Granulosicoccus coccoides sp. nov. is proposed. The type strain is Z 271T (=KMM 6014T=CIP 109923T).
