Utilization of Swine Wastewater as a Feedstock for the Production of Polyhydroxyalkanoates by Azotobacter vinelandii UWD

摘要

Azotobacter vine/andii UWD produced 0.69 g./~(-l) poly(hydroxybutyrate-co-hydroxyvalerate, PHBV) with 7.9 mol% hydroxyvalerate (HV) from twofold-diluted swine wastewater (SW). When supplemented with 20 9 . /~(-1) glucose, twofold-diluted SW increased copolymer production by 8.6 times. When three organic acids (acetate, propionate and butyrate) present in SW were supplemented with 20 g./~(-l) glucose, PHBV produc- tion wa
