1.14.18.3 analysis gene pmoA, which encodes the key subunit of the pMMO enzyme is commonly used as functional biomarker for surveying aerobic methane or ammonia oxidizers in the environment 744923 1.14.18.3 degradation pMMO can be used for biodegradation of mixtures of chlorinated solvents, i.e., trichloroethylene, trans-dichloroethylene, and vinyl chloride. If the concentrations are increased to 0.1 mM, pMMO-expressing cells grow faster and degrade more of these pollutants in a shorter amount of time than sMMO 671477 1.14.18.3 energy production teh enzyme can be used as biocatalysts for industrial activation of methane at relatively low temperatures required for breaking the highly stable C-H bond(s) -, 746420 1.14.18.3 environmental protection gene pmoA, which encodes the key subunit of the pMMO enzyme is commonly used as functional biomarker for surveying aerobic methane or ammonia oxidizers in the environment 744923
