Methane (CH4) and carbon dioxide (CO2) are potent greenhouse gases produced as waste in carbon-based fuel processes. This study investigates the use of natural microbial communities to consume CH4 and CO2 and convert these gases into biomass. Seawater enriched with nutrients was exposed to a gas stream containing CH4 and CO2 under either light or dark conditions. https://www.roneverhart.com/MagnaFlow-2000-Dodge-Durango-California-Grade-CARB-Compliant-Direct-Fit-Catalytic-Converter/
