In 2019, we provided the first detailed description of an atmMOB, Methylocapsa gorgona MG08. For this achievement we were rewarded the prestigous Cozzarelli prize by the national academy of sciences, USA, in the category Biomedical sciences.
M. gorgona MG08 is the only confirmed atmMOB in pure culture, allowing for the first time detailed physiological studies of these enigmatic bacteria. LoAir will refine the groundbreaking cultivation techniques that allowed isolation of M. gorgona MG08 to enable fully controlled physiological experiments. We will use M. gorgona MG08 as a model organism to study energy, carbon and nitrogen harvest during growth on atmospheric methane. We will also use our cultivation platform to identify which other types of methane oxidizing bacteria can grow on atmospheric methane. Finally, we will create atmospheric compositions predicted for the future and past to study how increased methane concentrations affect the physiology and methane capture efficiency of atmMOB. This way, LoAir will provide fundamental knowledge about atmMOB. In the extension of LoAir, this knowledge may be used to understand the function of atmospheric methane oxidizing bacteria in the environment and predict their role in scenarios for a warmer future.
