Known for their ability to remove methane from the environment and convert it into a usable fuel, methanotrophic
bacteria have long fascinated researchers.
The study published in the journal Science has found that the enzyme, present in the methanotrophic
bacteria, responsible for the conversion of methane into methanol catalyses the reaction at a site that contains only one copper ion.
In principle, a mixing process between cave air (with depleted C[H.sub.4] due to methanotrophic
activity) and a potential biogenic source (with [delta][sup.13][C.sub.CH4] roughly -65 [per thousand], according to Figure 8) is discarded because these data points of residual C[H.sub.4] with lighter [delta][sup.13][C.sub.CH4] do not fit properly with the hypothetical mixing curve between both end-members.
"Fatty acid and bulk stable carbon isotope values of cave-adapted shrimp suggest that carbon from methanotrophic
bacteria comprises 21% of their diet, on average.
The two biotic processes that determine the net methane (C[H.sub.4]) exchange between soils/ecosystems and the atmosphere are methane production by strictly anaerobic methanogenic Archaea (Methanogens) and methane consumption by methanotrophic
activity tends to be greater in forest soils than grasslands, with dryland arable soils typically having much lower uptake potential (Le Mer and Roger 2001).
