Polyhydroxyalkanoate Synthesis by into a Sustainable Sugarcane Biorefinery Concept.

Polyhydroxyalkanoate (PHA) bioplastic was synthesized by MA13 from carbon sources and industrial byproducts related to sugarcane biorefineries: sucrose, xylose, molasses, vinasse, bagasse hydrolysate, yeast extract, yeast autolysate, and inactivated dry yeast besides different inorganic nitrogen sources. Sugarcane molasses free of pre-treatment was the best carbon source, even compared to pure sucrose, with intracellular polymer accumulation values of 41.1-46.
