Poly(3-hydroxybutyrate) production from swine wastewater and waste vegetable oil by Cupriavidus necator in nonsterile bioreactors

Swine wastewater (SW), rich in nitrogen and phosphorus, and waste vegetable oil (WVO) are abundant feedstocks with potential for microbial biopolymers production. However, high polyhydroxyalkanoates (PHA) yields under nonsterile conditions remain challeng
