Аннотация Cyanobacteria have many unexploited potential for natural products with a huge variability in structure and biological activity. Their products are species specific and substrate + growth condition specific. Under extreme/stress conditions they are reported to produce several biopolymers like EPS, PHA etc., which can be produced extracellularly and intracellularly respectively. Polyhydroxyalkanoates are polymers of biological origin, they are also capable of being completely broken down to water and carbon dioxide by microorganisms found in a wide range of environments, such as soil, water, and sewage. We have studied marine cyanobacteria Spirulina subsalsa from Veraval coast, Gujarat, India, producing PHA under increased Sodium chloride (NaCl) concentration (5% enhancement to the ASN III medium), The biopolymer was chemically characterized through FTIR, NMR, TGA, and DSC. The present study shows increased PHA accumulation in Spirulina subsalsa by two fold increased NaCl concentration in the growth media.
