CHEMICAL ANALYSIS OF PIGMENT PRODUCED BY HALOALKALOTOLERANT BACTERIA PARACOCCUS BEIBUENSIS SL2
Paracoccus beibuensis SL2 is a halo-alkalotolerant bacteria isolated from Lonar Crater, Buldhana, Maharashtra, India and was identified by conventional and advanced techniques. The 16s rRNA sequence was deposited to NCBI GenBank with accession number KY129665. In recent studies the bright orange pigment produced by Paracoccus beibuensis SL2 was extracted and purified. The analysis of purified pigment was done by spectrophotometric method, chemical method, TLC, FT-IR and HPLC to know the chemical nature of pigment. The overall studies showed that bright orange pigment produced by Paracoccus beibuensis SL2 is a carotenoid group pigment which is mainly a xanthophyll pigment showing similar characters with that of Astaxanthin. It has a great commercial value as a natural colorant and therapeutic molecule.
