Methanotrophic bacteria represent a potential route to methane utilization and mitigation of
methane emissions. In the first step of their metabolic pathway, aerobic methanotrophs use …

Methane is a potent greenhouse gas that contributes significantly to climate change and is
primarily regulated in Nature by methanotrophic bacteria, which consume methane gas as …

Natural gas is a mixture of low molecular weight hydrocarbon gases that can be generated
from either fossil or anthropogenic resources. Although natural gas is used as a …

Copper is an important micronutrient required as a redox co-factor in the catalytic centers of
enzymes. However, free copper is a potential hazard because of its high chemical reactivity …

Particulate methane monooxygenase (pMMO) is an integral membrane metalloenzyme that
catalyses the conversion of methane to methanol. Knowledge of how pMMO performs this …

Publisher Summary This chapter discusses the metabolic aspects of aerobic obligate
methanotrophy. Aerobic methanotrophs are a unique group of gram-negative bacteria that …

Methane oxidation in soils is mostly accomplished by methanotrophic bacteria. Little is
known about the abundance of methanotrophs in soils, since quantification by cultivation …

Methanotrophic bacteria oxidize methane to methanol in the first step of their metabolic
pathway. Two forms of methane monooxygenase (MMO) enzymes catalyze this reaction …

Methane oxidation can occur in both aerobic and anaerobic environments; however, these
are completely different processes involving different groups of prokaryotes. Aerobic …

Autotrophic ammonia-oxidizing bacteria use the essential enzyme ammonia
monooxygenase (AMO) to transform ammonia to hydroxylamine. The amo operon consists …
