Enhancement of methane oxidation with effective methanotrophic mixed cultures
The emission of CH 4 from landfill is ranked third among the anthropogenic CH 4 sources and ranged between 19-40Tg/yr. The Microbial oxidation of landfill methane plays a significant role in reducing the emissions to the atmosphere. This study was carried out to the investigate the impact of several...

The emission of CH 4 from landfill is ranked third among the anthropogenic CH 4 sources and ranged between 19-40Tg/yr. The Microbial oxidation of landfill methane plays a significant role in reducing the emissions to the atmosphere. This study was carried out to the investigate the impact of several parameters on methane(CH 4) oxidation, using compost as biocover. Addition of dedicated methanotrophic bacterial cultures was also included..
