A novel yellow-pigmented, agarolytic bacterial strain, designated ZC1T, was isolated from the surface of the marine red alga Porphyra haitanensis collected near Nan Ao Island, Guangdong province, China. The isolate was Gram-stain-negative, strictly aerobic and rod-shaped and displayed β-galactosidase, alkaline phosphatase, catalase and oxidase activities. The predominant cellular fatty acids were iso-C15:0, summed feature 3 (comprising C16:1ω7c and/or iso-C15:0 2-OH) and iso-C17:0 3-OH. The major menaquinone was menaquinone 6 (MK-6). The DNA G+C content was 32.8 mol%. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain ZC1T was closely related to members of the genus Aquimarina in the family Flavobacteriaceae, phylum Bacteroidetes. Based on phylogenetic and phenotypic evidence, strain ZC1T (=CCTCC AB 2010229T=NBRC 107695T) represents the type strain of a novel species in the genus Aquimarina, for which the name Aquimarina agarilytica sp. nov. is proposed.
一株从中国广东省南澳岛附近采集的海洋红藻紫菜表面分离得到的新型黄色、琼脂分解细菌菌株，被命名为 ZC1T。该分离物革兰氏染色阴性，严格需氧，呈杆状，显示β-半乳糖苷酶、碱性磷酸酶、过氧化氢酶和氧化酶活性。主要细胞脂肪酸为 iso-C15:0、特征 3 总和（包括 C16:1ω7c 和/或 iso-C15:0 2-OH）和 iso-C17:0 3-OH。主要的menaquinone 是menaquinone 6（MK-6）。DNA G+C 含量为 32.8 mol%。16S rRNA 基因序列的系统发育分析表明，菌株 ZC1T 与黄杆菌科黄杆菌属的成员密切相关，位于厚壁菌门。基于系统发育和表型证据，菌株 ZC1T（=CCTCC AB 2010229T=NBRC 107695T）代表了 Aquimarina 属的一个新种的模式株，建议将其命名为 Aquimarina agarilytica sp. nov.。
