Production of Polyhydroxyalkanoates and Astaxanthin from Lignocellulosic Biomass

Short Introductive summary

Microbial-derived bioplastics are receiving more attention and are a potential option for ecological sustainability. Lignocellulosic biomass is the ultimate resource for the production of second-generation biofuels and biochemicals. In this study, lignocellulosic biomass (corn cob) was first pretreated and hydrolyzed to produce fermentable sugars. Then, polyhydroxyalkanoates (PHA) and astaxanthin were produced through batch and cell retention cultures of two strains, Bacillus megaterium ALA2 and Paracoccus sp. LL1 using corn cob hydrolysate as a carbon source. This study demonstrates that bioplastic PHA and high value-added astaxanthin can be economically produced from lignocellulosic biomass as an inexpensive renewable resource.
