%X Two novel Gram staining negative, slow growing, halotolerant rod shaped cells designated as strains Mi-7T and Mi-8, forming pin-point colonies on halophilic media were isolated during a study of microbial diversity of a salt-pan in the state of Tamilnadu, India. Both the strains had an obligate requirement of 1% (w/v) NaCl for growth and were halotolerant growing at NaCl concentrations of up to 20% in media. The strains however showed inability to utilize majority of substrates as sole carbon sources for growth and in fermentation reactions. Molecular phylogenetic analyses based on 16S rRNA gene sequence analysis revealed their closest phylogenetic neighbor as genus Marinobacter with whom they showed highest sequence similarity of 93.6% and even lower with the type species M. hydrocarbonoclasticus DSM 8798T (91.1%). Similarities with other genera within the family Alteromonadaceae were below 91.0%. However the two strains were very closely related to each other at 99.9% sequence similarity and DNA-DNA hybridization analyses confirmed their placement in the same species. The DNA G+C content of both strains was 65 mol%. Using polyphasic taxonomy data obtained from this study, strains Mi-7T and Mi-8 represent two strains of the same species of a novel genus for which the name Tamilnaduibacter salinus gen. nov., sp. nov., is proposed; the type strain of the novel species is Mi-7T (=MTCC 12009T =DSM 28688T).
