Polyhydroxyalkanoates production by mixed methanotrophic culture

Microbial synthesis of biopolymers from methane presents an environmentally friendly alternative to traditional plastics production. The effectiveness of mixed methanotrophic cultures for the production of polyhydroxyalkanoates (PHAs) from CH4 was assessed, along with the impact of various co-substrates on PHA copolymer composition. The microbial community dynamics in a CSTR under various operational conditions are investigated.

以甲烷为原料通过微生物合成生物聚合物，为传统塑料生产提供了环境友好的替代方案。本研究评估了混合甲烷氧化菌培养物以甲烷（CH₄）为原料生产聚羟基脂肪酸酯（polyhydroxyalkanoates, PHAs）的效能，并考察了多种共底物对PHA共聚物组成的影响；同时探究了连续搅拌釜式反应器（CSTR）在不同运行条件下的微生物群落动态变化。
