The Aeolian archipelago is known worldwide for its volcanic activity and hydrothermal emissions, of mainly carbon dioxide and hydrogen sulfide. Hydrogen, methane, and carbon monoxide are minor components of these emissions which together can feed large quantities of bacteria and archaea that do contribute to the removal of these notorious greenhouse gases. Here we analyzed the metagenome of samples taken from the Levante bay o...

The genus Methylobacter is considered an important and often dominant group of aerobic methane-oxidizing bacteria in many oxic ecosystems, where members of this genus contribute to the reduction of CH 4 emissions. Metagenomic studies of the upper oxic layers of geothermal soils of the Favara Grande, Pantelleria, Italy, revealed the presence of various methane-oxidizing bacteria, and resulted in a near complete metagenome assem...

Summary Growth of M ethylacidiphilum fumariolicum S olV , an extremely acidophilic methanotrophic microbe isolated from an I talian volcanic mudpot, is shown to be strictly dependent on the presence of lanthanides, a group of rare earth elements ( REEs ) such as lanthanum ( Ln ), cerium ( Ce ), praseodymium ( Pr ) and neodymium ( Nd ). After fractionation of the bacterial cells and crystallization of the methanol dehydrogenase...
