Abstract A novel thermophilic, anaerobic and organotrophic bacterium, designated strain MC3T, was isolated from a coastal thermal spring on Ile Saint-Paul in the Southern Indian Ocean. Cells of strain MC3T were motile rods, 0.8-1.0 microm wide and 1.0-2.4 microm long during exponential phase and up to 7.0 microm long during stationary phase. Strain MC3T was an anaerobic organotroph able to use diverse organic compounds. It was also able to reduce sulfur to sulfide. Growth was observed at temperatures ranging from 45 to 70 degrees C (optimum at 60 degrees C), between pH 5.5 and 7.5 (optimum at pH 6) and from 8 to 46 g NaCl l(-1) (optimum at 26 g l(-1)). The total G+C content of the genomic DNA was 26.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons indicated that strain MC3T was affiliated with the genus Marinitoga within the order Thermotogales. It shared 94.4-95.7% 16S rRNA gene sequence similarity with strains of other Marinitoga species; Marinitoga hydrogenitolerans was found to be the most closely related organism. Based on the data from the phylogenetic analysis and the physiological properties of the novel isolate, strain MC3T should be classified as a representative of a novel species, for which the name Marinitoga litoralis sp. nov. is proposed; the type strain is MC3T (=DSM 21709T =JCM 15581T).
