Abstract
Abstract The present study focusses on the extraction and characterization of polyhydroxyalkanoates from marine algal species by solvent extraction method. The following strains (i) Chlorella sp., (ii) Oscillatoria salina, (iii) Leptolyngbya valderiana and (iv) Synechococcus elongatus were used in the present research work. Algal strains were scaled up in ASN III medium and preliminary bioprospecting study was conducted to evaluate the growth profile of all algal strains in terms of dry cell weight. Of the strains studied, the higher growth was observed with Leptolyngbya valderiana and Chlorella sp. at about 2.75 g/L whereas Oscillatoria salina and Synechococcus elongatus showed low dry cell weight of 0.99 g/L and 0.32 g/L respectively. In addition, extraction of polyhydroxyalkanoates from the algal strains were carried out and characterized. Thermo Gravimetric Analysis and Differential Scanning Calorimetry studies were conducted to determine the thermal stability and thermal properties of the synthesized PHA respectively. All the PHAs were thermally stable below 260 °C. PHA obtained from Leptolyngbya valderiana was found to be more thermally stable compared to the PHA obtained from other algal species.
