Non-conventional gas phase remediation of volatile halogenated compounds by dehydrated bacteria [PDF]

, 2009
Traditional biological removal processes are limited by the low solubility of halogenated compounds in aqueous media. A new technology appears very suitable for the remediation of these volatile organic compounds (VOCs). Solid/gas bio-catalysis applied

Bioremediation of halogenated compounds: comparison of dehalogenating bacteria and improvement of catalyst stability [PDF]

, 2006
Five bacterial strains were compared for halogenated compounds conversion in aqueous media. Depending on the strain, the optimal temperature for dehalogenase activity of resting cells varied from 30 to 45 degrees C, while optimal pH raised from 8.4 to 9 ...
