Isolation and characterization of a rare polar carotenoid 1’-OH-4-keto-ϒ-carotene from an indigenously isolated Rhodococcus kroppenstedtii MH715196

The catabolic diversity and biocatalytic potential in members of genus Rhodococcus makes it an ideal industrial workhouse for metabolite production. Despite their applicability, Rhodococci are least explored carotenoids, located cell membrane. goal the present study was to identify carotenoids kroppenstedtii MH715196. UV-Vis spectral data molecular mass estimates showed that principal carotenoid extracted from R. MH715196 1’-OH-4-keto-ϒ-carotene. Biosynthetic route 1’-OH-4-keto-ϒ-carotene postulated on basis co-relation with putative biosynthetic genes identified genome reference strains kroppenstedtii. Three key enzymes, were then considered phylogenetic analysis establish relationship across leading way identification other species. would be first report a rare polar which could potentially as food colorant hydrophilic matrices like jams, jellies, beverages etc.
