Abstract

A novel alphaproteobacterium, strain RAM11, belonging to the family was isolated from the pool water of a thermal bath in Budapest, Hungary. Based on the 16S rRNA gene sequence strain RAM11 shows the highest sequence similarity values to Casida A (97.44 %), to syn. CFNEI 156 (96.87 %) and to Po 20/26 (96.76 %). The new bacterium is strictly aerobic, its optimum growth occurs at 20–37 °C, between pH 7 and 9 and without NaCl. It is motile due to a single polar flagellum, capable of budding and forms rosettes in liquid culture. The major isoprenoid quinone of strain RAM11 is Q-10, the major cellular fatty acids are C 7 and 11-MeC 7. The polar lipid profile contains phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylcholine, an unidentified aminolipid and an unidentified phospholipid. The G+C content of DNA of the type strain is 62.9 mol%. Strain RAM11 (=DSM 29853=NCAIM B.02618) is proposed as type strain of a new genus and species with the proposed name gen. nov., sp. nov.
