Chengkuizengella axinellae sp. nov., a symbiotic bacterium isolated from a marine sponge of the genus Axinella.

A Gram-stain-positive, strictly aerobic, creamy-white colored, endospore-forming and non-motile rods strain, designated as strain 2205SS18-9, was isolated from a marine sponge, Axinella sp. collected from Seopseom Island, Republic of Korea. Optimal growth of strain 2205SS18-9 was observed at 25-30 °C, pH 6.

sp. nov., isolated from a marine sponge (), and reclassification of as nom. nov.

A Gram-stain-negative, aerobic and non-motile rods strain, designated as strain 2012CJ39-3, was isolated from a marine sponge, , collected on Chuja Island, Republic of Korea. Optimal growth of strain 2012CJ39-3 was observed at 25 °C, pH 7.0 and in the presence of 2.

sp. nov., isolated from .

A Gram-stain-negative, rod-shaped, motile via polar flagellum, facultatively aerobic, light-yellow, bacterium (designated 188UL20-2) was isolated from a mussel sample of collected on Ulleung Island, Ulleung-gun, Gyeongsangbuk-do, Republic of Korea. On the basis of 16S rRNA gene sequencing results, strain 188UL20-2 clustered with species of the genus and appeared closely related to DSM 23086 (96.59%), DSM 26147 (96.
