Methylomonadaceae was the active and dominant methanotroph in Tibet lake sediments.

ABSTRACT: Methane (CH₄), an important greenhouse gas, significantly impacts the local and global climate. Our study focused on the composition and activity of methanotrophs residing in the lakes on the Tibetan Plateau, a hotspot for climate change research. Based on the field survey, the family Methylomonadaceae had a much higher relative abundance in freshwater lakes than in brackish and saline lakes, accounting for ~92% of total aerobic methanotrophs. Using the microcosm sediment incubation with ¹³CH₄ followed by high throughput sequencing and metagenomic analysis, we further demonstrated that the family Methylomonadaceae was actively oxidizing CH₄. Moreover, various methylotrophs, such as the genera Methylotenera and Methylophilu
