  • Bioprocess for the simultaneous production of polyhydroxybutyrate and violacein pigment from himalayan bacterium iodobacter sp. PCH 194
    Patent number: 12680073
    Abstract: The present disclosure provides a bioprocess for the simultaneous production of Polyhydroxybutyrate (PHB) and Violacein pigment in a single fermentation using a Himalayan bacterial isolate Iodobacter sp. PCH 194, having accession number MTCC 25171. PHB has plastic properties, renewable origin and bio-degradable nature. It can be used for various packaging applications replacing the petrochemicals-based plastics, thus providing greener alternative to environment. Violacein pigment has anti-oxidant, anti-tumoral, anti-bacterial, and photo-protective properties and can be used in cosmetics and pharmaceuticals applications. The present disclosure provides production process of two valuable products i.e. PHB and violacein pigment in a single bioprocess, therefore, is economically attractive, time saving, and commercially feasible process.
