WebMar 31, 2012 · The poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)-degrading strain Acidovorax sp. HB01 was isolated from an activated sludge sample. A novel PHBV depolymerase with a molecular weight of 43.4 kDa was purified to homogeneity from the culture supernatant of the HB01 strain. The optimum pH and temperature of the PHBV … Poly(3-hydroxybutyrate) depolymerase (EC 3.1.1.75, PHB depolymerase, systematic name poly[(R)-3-hydroxybutanoate] hydrolase) is an enzyme used in the degradation processes of a natural polyester poly(3-hydroxyburate). This enzyme has growing commercialization interests due to it implications in biodegradable plastic decomposition. It catalyzes the reaction bizbash swan and dolphin
