Abstract
Two bacterial strains (KOPRI 13537 and KOPRI 13650) among the marine bacteria isolated from young biofilm were investigated to determine taxonomic status. Based on the 16S rRNA sequence, KOPRI 13537 and KOPRI 13650 should be placed in the genus Rhodobacter and genus Psychroserpens, respectively. Major fatty acids of KOPRI 13537 were C18:1w9tr, C16:0 and C16:1w9 and could assimilate arabinose, mannitol, maltose and citrate. Unlikely to the other members of genus Rhodobacter the isolate has no photosynthetic pigments. Major fatty acids of KOPRI 13650 were C18:1w9, C16
1w9 and a-C17:0. The isolate was non-motile rod form. Optimal growth was observed at 30 oC and 4~5% of NaCl concentration. Based on the phenotypic and phylogenetic data, it is proposed that KOPRI 13537 should be proposed as Rhodobacter incheonensis sp. nov., and KOPRI 13650 as Psychroserpens mesophilus sp. nov.
