The Agharkar Research Institute of Pune has isolated 45 strains of methanotrophic bacteria. These bacteria are capable of reducing methane emissions in rice plants. Highlights: Apart from isolating the strains, the scientists have also created methanotrophic culture. The isolated bacteria were from southern and western India. What are Methanotrophs? Methanotrophs are environmental organisms that have a major role in cycling of methane. They oxidize methane in the environment. The methanotrophic bacteria oxidize methane through anaerobic metabolism. The methanotrophs are use as bio-inoculants.
