Abstract

Two marine heterotrophic bacteria, A5K-61 and A5K-106, were isolated from marine animals. 16S rRNA gene sequence analysis data showed that the isolates were affiliated with the genus ; highest 16S rRNA gene sequence similarity values were found with DSM 13754 (97.5 and 98.1 %, respectively). DNA–DNA hybridization values of strains A5K-61 and A5K-106 with DSM 13754 (22.2–49.1 %) were clearly below 70 %, the generally accepted limit for species delineation. The isolates produced a brown diffusible pigment. The major respiratory quinone was Q-8 and the predominant cellular fatty acids were C 7 and C. Based on DNA–DNA hybridization data, some biochemical characteristics and 16S rRNA gene sequence comparison, the isolates represent two novel species of the genus , for which the names sp. nov. (type strain A5K-106 =MBIC08328 =NCIMB 14418 =NBRC 104231) and sp. nov. (type strain A5K-61 =MBIC08329 =NCIMB 14417 =NBRC 104232) are proposed.
