A microcosm test for potential mineralization of chlorinated compounds under coupled aerobic/anaerobic conditions.
TL;DR: The feasibility of using a mineralization test under coupled aerobic/anaerobic conditions was demonstrated and perchloroethylene (PCE) mineralization tests confirmed the effectiveness of the proposed methodology as well as PCE mineralization under coupled conditions.

TL;DR: The results demonstrated that the injection of isopropanol served to maintain an active MTBE degrading biomass in the biofilter and that this system could be used to effectively treat MTBE contaminated groundwater.

TL;DR: In this article, the concentration of methyl tert -butyl ether (MTBE) and tert -amyl methyl methyl ether (TAME) dans an aquifere pollue par ces ethers, on utilise dans un procede de type biobarriere ou bio-filtre un support mineral nouveau for the fixation des bacteries, and en particulier de Mycobacterium austroafricanum I-2562, ledit support mineral comprenant de la perlite.

TL;DR: To reduce the concentration of methyl tert-butyl ether (MTBE) or tert-amyl methyl ether (TAME) in an aquifer polluted by these ethers, a new mineral support for fixing bacteria, and in particular Mycobacterium austroafricanum I-2562, is used in a biobarrier or biofilter-type process as mentioned in this paper.

TL;DR: In this paper, the authors show that Mycobacterium austroafricanum I-2562 is induced to grow in aerobic conditions in the presence of a growth substrate comprising the ether(as carbon source and energy) ; the ether is degraded by the bacteria to carbon dioxide and water.
