A novel marine, Gram-stain-negative, oxidase- and catalase- positive, rod-shaped bacterium, designated strain AK6(T), was isolated from marine aquaculture pond water collected in Andhra Pradesh, India. The fatty acids were dominated by iso-C15:0, iso-C17:1ω9c, iso-C15:1 G, iso-C17:0 3-OH and anteiso-C15:0. Strain AK6(T) contained MK-7 as the sole respiratory quinone and phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified phospholipid and seven unidentified lipids as polar lipids. The DNA G+C content of strain AK6(T) was 45.6 mol%. Phylogenetic analysis showed that strain AK6(T) formed a distinct branch within the family Cyclobacteriaceae and clustered with Aquiflexum balticum DSM 16537(T) and other members of the family Cyclobacteriaceae. 16S rRNA gene sequence analysis confirmed that Aquiflexum balticum DSM 16537(T) was the nearest neighbour, with pairwise sequence similarity of 90.1%, while sequence similarity with the other members of the family was <88.5%. Based on differentiating phenotypic characteristics and phylogenetic inference, strain AK6(T) is proposed as a representative of a new genus and species of the family Cyclobacteriaceae, as Mariniradius saccharolyticus gen. nov., sp. nov. The type strain of Mariniradius saccharolyticus is AK6(T) (=MTCC 11279(T)=JCM 17389(T)). Emended descriptions of the genus Aquiflexum and Aquiflexum balticum are also proposed.
