The assessment of bacterial diversity and bioprospection of the high-altitude lake Suraj Tal microorganisms for potent antimicrobial activities revealed the presence of two Gram-stain-variable, endospore-forming, rod-shaped, aerobic bacteria, namely IHBB 9852T and IHBB 9951. Phylogenetic analysis based on 16S rRNA gene sequence showed the affiliation of strains IHBB 9852T and IHBB 9951 within the genus Paenibacillus, exhibiting the highest sequence similarity to Paenibacillus lactis DSM 15596T (97.8% and 97.7%) and less than 95.9% similarity to other species of the genus Paenibacillus. DNA-DNA relatedness among strains IHBB 9852T and IHBB 9951 was 90.2%, and with P. lactis DSM 15596T, was 52.7% and 52.4%, respectively. The novel strains contain anteiso-C15:0, iso-C15:0, C16:0 and iso-C16:0 as major fatty acids, and phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol were predominant polar lipids. The DNA G+C content for IHBB 9852T and IHBB 9951 was 52.1 and 52.2Â mol%. Based on the results of phenotypic and genomic characterisations, we concluded that strains IHBB 9852T and IHBB 9951 belong to a novel Paenibacillus species, for which the name Paenibacillus ihbetae sp. nov. is proposed. The type strain is IHBB 9852T (=MTCC 12459TÂ =Â MCC 2795TÂ =Â JCM 31131TÂ =Â KACC 19072T; DPD TaxonNumber TA00046) and IHBB 9951 (=MTCC 12458Â =Â MCC 2794Â =Â JCM 31132Â =Â KACC 19073) is a reference strain.
