Effect of selected monoterpenes on methane oxidation, denitrification, and aerobic metabolism by bacteria in pure culture
Article Abstract:
The effect of several monoterpenes on methane oxidation by pure cultures of the methanotrophs Methylosinus trichosporium OB3b and Methylobacter luteus, denitrification by six environmental isolates and aerobic metabolism by heterotrophic laboratory cultures were investigated. Inhibition occurred to various extents and was transient. Complete inhibition of methane oxidation by Methylosinus trichosporium OB3b with 1.1 nM (-)-alpha-pinene lasted for more than two days. Inhibition was greater in conditions under which particulate methane monooxygenase was expressed.

Microbial degradation of monoterpenes in the absence of molecular oxygen
Article Abstract:
The bacteria Pseudomonas citronellolis can draw carbon and energy by oxidizing acyclic, mono- and bicyclic monoterpenes under anaerobic conditions. Seven strains of denitrifying bacteria were isolated based on monoterpene oxidation. This process of oxidation of monoterpenes by anaerobic bacteria can be used to anaerobically treat and purify acrid wastewaters in the food industry, thereby reducing the release of nonmethane hydrocarbons into the atmosphere.

Community size and metabolic rates of psychrophilic sulfate-reducing bacteria in Arctic marine sediments
Article Abstract:
Research was conducted to examine sulfate reduction rates (SRRs) in cold and temperate sediments by quantifying sulfate reducers in two polar sediments and by comparing specific SRRs of new psychrophilic isolates to those of known mesophilic sulfate-reducing bacteria. Results suggest that psychrophilic sulfate reducers have considerably higher specific metabolic rates than their mesophilic counterparts at similarly low temperatures.
