%X A Gram positive, motile, short rod shaped, orange pigmented bacterium strain IMTB-3094T, isolated from water sample, collected from Tikkar Tal Lake, Haryana and was subjected to a detailed polyphasic taxonomic study. Strain IMTB-3094T, matched with most of the phenotypic and chemotaxonomic properties of the genus Exiguobacterium and represented novel species. According to 16S rRNA gene sequence analysis, strain IMTB-3094T belonged to the genus Exiguobacterium. The strain IMTB-3094T exhibited highest 16S rRNA gene sequence similarity with Exiguobacterium mexicanum MTCC 7759T (99.5%) followed by Exiguobacterium aurantiacum MTCC 6414T (99.1%), Exiguobacterium aestuarii MTCC 7750T (98.0%), Exiguobacterium profundum MTCC 10851T (98.0%) and Exiguobacterium marinum MTCC 7751T (98.0%). The G+C content of the genomic DNA of strain IMTB-3094T was 53.2 mol %, while DNA-DNA relatedness study confirmed that it represents a novel species. The major fatty acids of the strain iso-C17:0 (16.1%), anteiso-C13:0 (19.0%), iso-C13: 0 (11.9%), iso-C15:0 (9.8%) and iso E C17:1 (12.7%). Predominant quinones are MK-7 (55.0%), MK-6 (26.0%) and MK-8 (12.0%) in minor amount. Based on phenotypic, chemotaxanomic and phylogenetic analysis, the strain IMTB-3094T should be classified as novel species of the genus Exiguobacterium for which the name Exiguobacterium aquaticum sp. nov. is proposed. The type strain is IMTB-3094T (=MTCC 10958T= JCM 17977T).
