Abstract:
A halophilic, alkalitolerant bacterium, strain 20AG T , was isolated from an algal mat collected from a sulfurous spring located in Santa Maria Incaldana (Mondragone, Campania Region, southern Italy). The isolate is Gram-positive, ferments several carbohydrates and has motile, rod-shaped cells that do not sporulate. The isolate grows at pH 6·5–9·5 and in 5–20 % NaCl. On the basis of 16S rRNA gene sequence similarity, the strain was shown to belong to the genus Oceanobacillus ; strain 20AG T showed 96·6 % 16S rRNA gene sequence similarity to the type strain of Oceanobacillus iheyensis , DSM 14371 T , and 99·5 % similarity to Oceanobacillus oncorhynchi NCIMB 14022 T . Levels of DNA–DNA relatedness between strain 20AG T and O. iheyensis DSM 14371 T and O. oncorhynchi NCIMB 14022 T were respectively 29·4 and 59·0 %. The G+C content of the DNA of strain 20AG T was 40·1 mol%. The predominant respiratory quinone was MK-7, phosphatidylglycerol and phosphatidylcholine were the predominant polar lipids and minor phospholipids were also detected. ai-C14 : 0, ai-C15 : 0 and i-C15 : 0 were the major fatty acids. Strain 20AG T accumulated osmolytes and produced exopolysaccharide. On the basis of phenotypic characteristics, phylogenetic data and DNA–DNA relatedness data, isolate 20AG T should be designated as the type strain of a subspecies of Oceanobacillus oncorhynchi , for which the name Oceanobacillus oncorhynchi subsp incaldanensis subsp. nov. is proposed. The type strain is 20AG T (=DSM 16557 T =ATCC BAA-954 T ).
