Biopolymer of polyhydroxyalkanoates

Polyhydroxyalkanoates (PHAs) are the most fascinating group of biopolymer emerges to be the potential candidate for substitute of synthetic plastics. However, high cost of both upstream and downstream processing has limited their successful commercialization. Among these two processes, recovery methodology of PHAs significantly affects the overall production economics.

This study aims to use sweet sorghum juice (SSJ) to produce an environmentally friendly biopolymer of polyhydroxyalkanoates (PHAs) by bacteria isolated from soil. Among 18 isolates, only 3 isolates, coded as S4, S6, and S11, were chosen to produce PHA via batch fermentation compared to 3 strains of Alcaligenes eutrophus, A. latus, and Hydrogenophaga sp., respectively, under controlled conditions at pH 7, 35 °C, and 20 g/L of initial total sugar in the SSJ.

However, these bioplastics are currently far more expensive than petrochemical plastics.
