Production, ultrasonic extraction, and characterization of poly (3‐hydroxybutyrate) (PHB) using Bacillus megaterium and Cupriavidus necator

Biodegradable polymer polyhydroxyalkanoates are one of the promising alternatives for conventional plastics. The present article focuses on a modified and novel method for the synthesis of poly (3‐hydroxybutyrate) (PHB) by two microorganisms, viz. Bacillus megaterium and Cupriavidus necator . These microbial cells were grown over fructose as a carbon source, and the produced PHB was recovered using ultrasound as well as solvent assisted...
