A novel yellow-pigmented, agarolytic bacterial strain, designated ZC1(T), 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 beta-galactosidase, alkaline phosphatase, catalase and oxidase activities. The predominant cellular fatty acids were iso-C-15:0, summed feature 3 (comprising C-16:1 omega 7c and/or iso-C-15:0 2-OH) and iso-C-17:0 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 ZC1(T) was closely related to members of the genus Aquimarina in the family Flavobacteriaceae, phylum Bacteroidetes. Based on phylogenetic and phenotypic evidence, strain ZC1(T) (=CCTCC AB 2010229(T) =NBRC 107695(T)) represents the type strain of a novel species in the genus Aquimarina, for which the name Aquimarina agarilytica sp. nov. is proposed.
