Methanotrophs mediated biogas valorization: Sustainable route to polyhydroxybutyrate production.

This study explores the ability of methanotrophs to convert biogas into biopolymers, addressing HS as a limitation in the utilization of biogas as a carbon source for bioconversion. Transcriptomic analysis was conducted to understand the growth and changes in the expression patterns of Type I and II methanotrophs under varying HS concentrations. Results suggested that Type II methanotrophs can possess a native HS utilization pathway.

Comparative genomic analysis of Methylocystis sp. MJC1 as a platform strain for polyhydroxybutyrate biosynthesis.

Biodegradable polyhydroxybutyrate (PHB) can be produced from methane by some type II methanotroph such as the genus Methylocystis. This study presents the comparative genomic analysis of a newly isolated methanotroph, Methylocystis sp. MJC1 as a biodegradable PHB-producing platform strain.
