Abstract:
On the basis of data from phenotypic and genotypic characterization and analysis of 16S rRNA gene sequences, two novel species belonging to the genus Sulfitobacter are described. Strains KMM 3584 T , a pale-yellowish, non-motile strain isolated from a starfish ( Stellaster equestris ), and KMM 3554 T , which is motile by means of a single subpolar flagellum and was isolated from sea grass ( Zostera marina ), are marine, Gram-negative, aerobic, rod-shaped organisms. Both strains have the ability to degrade gelatin, but not casein, chitin, agar, DNA, Tween 80 or starch. Strain KMM 3584 T decomposed alginate and grew at NaCl concentrations of 1–8 % and temperatures of 12–37°C, whereas strain KMM 3554 T grew in 1–12% NaCl and at temperatures of 10–30°C. The predominant fatty acid was 18:1 ω 7, amounting to up to 80% of the total fatty acids. The other characteristic feature was the presence of 18:2 isomers. The DNA G+C contents of KMM 3584 T and KMM 3554 T were respectively 60·0 and 63·7 mol%. The level of DNA similarity between the two strains was 33%. DNA from KMM 3584 T and KMM 3554 T had hybridization values of 5–24% and 10–41%, respectively, with DNA from the type strains of Sulfitobacter pontiacus , Sulfitobacter brevis , Sulfitobacter mediterraneus and Staleya guttiformis . It is proposed that strains KMM 3584 T (=LMG 20554 T =ATCC BAA-321 T ) and KMM 3554 T (=LMG 20555 T =ATCC BAA-320 T ) represent two novel species, Sulfitobacter delicatus sp. nov. and Sulfitobacter dubius sp. nov., respectively.
