Natural pigments were obtained and utilized from plants, insects and ores in prehistoric period and it has been over ruled by the synthetic dyes and pigments, inspite of its vast array of disadvantages to the ecosystem. The demand for natural pigments has triggered the researchers to look for an alternative approach, which could replace the synthetic pigments. Microorganisms such as algae, fungi, actinomycetes and bacteria play an interesting role in the world of colors with their chromogenecity. This study reports the isolation of chromogenic bacterial strain BRTSI-1 from the rhizosphere of Arachis hypogaea. The strain BRTSI-1 was identified as Staphylococcus aureus (NCBI accession number MH412806) based on their morphological, biochemical and 16S rDNA sequencing results. The culture condition for maximizing pigment production was found to be 30oC at neutral pH. The methanolic extract of the pigment was spectroscopically analyzed using UV- Vis spectrophotometry between 400-600 nm. FTIR analysis explained the functional groups present in the methanolic extract.
