Many bacterial isolates showed decolorisation of reactive red -11 as a sole source of carbon, among the strains, a potential thermophillic newly isolated and first time reporting dye degrading bacterial strain, Lysinibacillus boronitolerans CMGS-2 has been isolated from the textile dye treatment unit solapur, Maharashtra and identified by 16s rRNA. It was Motile and spore forming bacteria Showed decolorisation of 88.78% of reactive red - 11 dyes (200mg/liter) within 48 hours of incubation under static condition with dye as carbon source. Abiotic and biotic parameters were framed to enhance the capacity of isolate, finally 96.8% of decolourisation was achieved with 400mg/L RR-11, at pH-9, at temperature 45ºC, Inoculum concentration was 5ml, and 1gm/L yeast extract as nutritional source, within 12 hours of incubation. The novel characteristics of CMGS-2 was found, it showed decolorisation of 95.9% even at 50ºC temperature. The complete decolorisation of reactive red-11(RR-11) dye confirmed by using UV-VIS Spectrophotometer. It is deposited in the IMTECH, MTCC Chandigarh with MTCC number-12531.

Keywords: Thermophillic, Reactive red-11 (RR-11), IMTECH, MTCC
