ABSTRACT:
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 particularMycobacterium austroafricanumI-2562, said mineral support comprising perlite, is used in a biobarrier- or biofilter-type process.
