Influence of poly-β-hydroxybutyrate and it,s degrading bacteria on metabolic diversity of anaerobic bacteria in siberian sturgeon (Acipenser baerii) hindgut

Introduction:Poly-β-hydroxybutyrate (PHB) is a natural polymer that can be depolymerized by bacterial extracellular enzymes into β-hydroxybutyric acid monomers. Materials and methods: In this study, the effects of PHB and it’s degrading bacteria on the metabolic diversity of anaerobic bacteria in Si...

Description
Summary:Introduction:Poly-β-hydroxybutyrate (PHB) is a natural polymer that can be depolymerized by bacterial extracellular enzymes into β-hydroxybutyric acid monomers. Materials and methods: In this study, the effects of PHB and it’s degrading bacteria on the metabolic diversity of anaerobic bacteria in Siberian sturgeon hindgut were investigated in four treatments (Control, 2% PHB, combination of two degrading bacteria, 2% PHB + two bateria) for 60 days. The Shanon diversity index, Evenness and Pareto-Lorenz curve was calculated with BiologTM Ecoplates data. Results: The results indicated that using supplemented diets significantly increased Shanon index and evenness then control (P
