The production of polyhydroxyalkanoate (PHA) using CO2 through hydrogen-oxidizing bacteria under safe, non-explosive conditions is making impressive strides. present study aimed to evaluate and demonstrate the growth productivity PHA by Cupriavidus sp. CY-1 different conditions, thereby providing critical data for practical applications. experimental results highlighted efficiency strain in biosynthesis, achieving a rate 11.87 g L-1, which corresponds 90.6% yield when fermenting gaseous substrate composed H2 (70%), O2 (20%), (10%). also examined including concentrations 3.8% (v/v) at 6.5% (v/v). Furthermore, impact CO (30% higher) was assessed, revealing detrimental effect on production. Notably, addition Tween 80 significantly enhanced productivity. effective utilization has confirmed poly[(R)-3-hydroxybutyrate] (PHB) as valuable derived form PHA. By implementing two-step treatment with valeric acid, we successfully produced P(3HB-co-3HV) (PHBV) concentration 1.47 L-1. This achievement highlights potential enhance innovative strategies. examination phaC gene expression levels facilitated accurate predictions use from trichloroethylene (TCE) biodegradation faced concentration-related challenges; however, higher achieved phenol biodegradation, 1200 mg indicate substantial efficient
