Bioremediation of halogenated compounds: comparison of dehalogenating bacteria and improvement of catalyst stability.
نویسندگان
چکیده
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 9.0. The most effective dehalogenase activity for 1-chlorobutane conversion was detected with Rhodococcus erythropolis NCIMB13064 and Escherichia coli BL21 (DE3) (DhaA). The presence of 2-chlorobutane or propanal in the aqueous media could inhibit the 1-chlorobutane transformation.

متن کاملMolecular techniques in the biotechnological fight against halogenated compounds in anoxic environments
Microbial treatment of environmental contamination by anthropogenic halogenated organic compounds has become popular in recent decades, especially in the subsurface environments. Molecular techniques such as polymerase chain reaction-based fingerprinting methods have been extensively used to closely monitor the presence and activities of dehalogenating microbes, which also lead to the discovery...
متن کاملNon-conventional gas phase remediation of volatile halogenated compounds by dehydrated bacteria.
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 in VOC remediation can transform halogenated compounds directly in the gas phase using dehydrated cells as a bio-catalyst. The hydrolysis of vol...
متن کاملBiodiversity of dehalorespiring bacteria with special emphasis on polychlorinated biphenyl/dioxin dechlorinators.
A wide variety of haloorganic compounds undergo reductive dehalogenation by certain anaerobic microorganisms. Metabolic reductive dehalogenation is coupled with energy-conserving respiratory electron transport in which a halogenated compound is used as the terminal electron acceptor, the biological process called dehalorespiration or halorespiration. Dehalorespiring bacteria may play important ...
متن کاملDegradation of Alkanes in Contaminated Sites
Petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. To control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. It constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by ...
