A Gram-negative, aerobic, golden yellow, rod-shaped bacterium, a strain designated ICGEB-L15T, was isolated from the larval midgut of Anopheles stephensi captured in District Jhajjar, Haryana, India. The strain ICGEB-L15T grows at 30?50°C (optimum 30?37°C), pH 6.5?8.5 (optimum 7.0?8.0) and in the presence of 2% NaCl. The major fatty acids were iso-C15:0 (22.5% of total fatty acid), anteiso-C15:0 (16.5%), iso-C17:1 9c (10.3%), iso-C16:0 (7.3%), C16:0 (6.1%), and iso-C11:0 (5.3%). The strain showed the highest 16S rRNA gene sequence similarities with the type strains Pseudoxanthomonas daejeonensis KCTC 12207T (97.4%), Pseudoxanthomonas kaohsiungensis J36T (97.17%), and Pseudoxanthomonas mexicana AMX 26BT (97.11%). The DNA relatedness between ICGEB-L15T and Pseudoxanthomonas daejeonensis KCTC 12207T, Pseudoxanthomonas kaohsiungensis J36T and Pseudoxanthomonas mexicana AMX 26BT was 24.5%, 28.2%, and 33.6%, respectively. The G+C content of genomic DNA was 69.9 mol%. The major isoprenoid quinone of strain ICGEB-L15T was Q-8. The strain ICGEB-L15T represents a novel species of the genus Pseudoxanthomonas based on physiological, biochemical and phylogenetic properties; therefore, the name Pseudoxanthomonas icgebensis sp. nov. is proposed. The type strain is ICGEB-L15T (=KACC 14090T =DSM 22536T).
