Paracoccus beibuensis sl2a newcarotenoid producing bacterium isolated from hypersaline-hyperalkaline lonar crater, buldhana, maharashtra, india

In recent studies, bacterial isolate SL2 was screened out of 105 pigment producing bacteria isolated from hypersaline-hyperalkaline ecosystem i.e.Lonar Crater, Buldhana, Maharashtra, India, on the basis of pH and NaCl (%) tolerance and identified based on its morphological, biochemical and physiological properties. Identification at molecular level by 16s rRNA sequence analysis revealed 99.0% similarities of SL2 with Paracoccus beibuensis and sequence was deposited to NCBI Gen Bank with accession number KY129665. Members of Paracoccus sp. belongs tosub-class of proteobacteria and it is a member of family Rhodobacteriaceae. Carotenoid production is one of the properties of Paracoccus sp.Bacterium Paracoccus beibuensis isolated from Lonar Crater soil is non-motile, Gram-negative coccoid rod, tolerant to salt(1-6%), alkaline pH (6-12), catalase and oxidase positive and produces significant quantity of bright orange pigment which was confirmed by spectrophotometric analysis as carotenoid.
