Analysis of microbial efficiency in oxidizing low-concentration methane through biofiltration

Biofilters, columns of support media colonized by methane oxidizing microbial communities, can be used to mitigate low-concentration methane. Their oxidation efficiency is highly dependent on the microbial communities that inhabit the biofilter and their environmental conditions. Not enough research on these microbial communities has been conducted to effectively predict and optimize biofilter operation. We discovered that the microbial communities found in compost are most effective under high moisture conditions and when exposed to methane overtime.
