Aerobic proteobacterial methylotrophs in Movile Cave: genomic and metagenomic analyses.

ABSTRACT:

Background

Movile Cave (Mangalia, Romania) is a unique ecosystem where the food web is sustained by microbial primary production, analogous to deep-sea hydrothermal vents. Specifically, chemoautotrophic microbes deriving energy from the oxidation of hydrogen sulphide and methane form the basis of the food web.

Results

Here, we report the isolation of the first methane-oxidizing bacterium from the Movile Cave ecosystem, Candidatus Methylomonas sp. LWB, a new species and representative of Movile Cave microbial mat samples. While previous research has suggested a prevalence of anoxic conditions in deeper lake water and sediment, using small-scale shotgun metagenome sequencing, we show that metabolic genes encoding enzymes for aerobic methylotrophy are prevalent in sediment meta
