“…They can be categorised as chlorinated methanes, chlorinated ethanes, chlorinated ethenes, chlorinated fluorocarbons, chlorinated acetic acids, chlorinated propanoid compounds and chloro-1,3butadienes (Field and Sierra-Alvarez, 2004). Although some microorganisms are able to metabolise CAHs, they can be trapped in soils exhibiting a marked environmental persistence over periods of decades (Leisinger, 1996;Rockne and Reddy, 2003). Bioaccumulation of CAHs has also been reported and trace concentrations of CAHs have been found in species like Pacific Walrus (Odobenus rosmarus divergens) (Seagars and Garlich-Miller, 2001).…”

Halogenated organic compounds are a particular group of contaminants consisting of a large number of substances, and of great concern due to their persistence in the environment, potential for bioaccumulation and toxicity. Some of these compounds have been classified as persistent organic pollutants (POPs) under The Stockholm Convention and many toxicity assessments have been conducted on them previously. In this work we provide an overview of enzymatic assays used in these studies to establish toxic effects and dose-response relationships. Studies in vivo and in vitro have been considered with a particular emphasis on the impact of halogenated compounds on the activity of relevant enzymes to the humans and the environment. Most information available in the literature focuses on chlorinated compounds, but brominated and fluorinated molecules are also the target of increasing numbers of studies. The enzymes identified can be classified as enzymes: i) the activities of which are affected by the presence of halogenated organic compounds, and ii) those involved in their metabolisation/detoxification resulting in increased activities. In both cases the halogen substituent seems to have an important role in the effects observed. Finally, the use of these enzymes in biosensing tools for monitoring of halogenated compounds is described.

“…Fortunately, bioremediation is the microbial degradation of organic pollutants such as petroleum in soil and groundwater. This technique has the benefits of high treatment efficiency, low cost, relatively quick action, in site and ex site application, and compatibility with other techniques [5] [6] [7] [8].…”

Objective: The aim of study is to research the degradation characteristics of oil degrading Candida tropicalis (G-94). Methods: Effects of temperature, pH, oil concentration, salt concentration, inoculation amount, N and P source on the oil removal rate of G-94 were studied by single factor test. Meanwhile, the effects of temperature, pH, oil concentration and salt concentration on the oil removal rate of G-94 were optimized by orthogonal design. Result: The orthogonal design showed that the oil removal rate of G-94 could reach 25.83%, 28.56% and 30.90% at 10 d, 20 d and 40 d under the optimal conditions which was 25˚C, initial pH 8.0, oil concentration 1.0%, salt concentration 0.4%, inoculum amount 4%, the optimal N and P were (NH 4 ) 2 SO 4 and K 2 HPO 4 . Conclusion: This experiment studied the degradation characteristics of G-94, which paved the way for the remediation of petroleum contaminated soil.

Objective: In order to study low activity of petroleum-degrading strains. Methods: We added oil degrading strains to compost, the compost is made of soybean meal, corn flour, bran and sawdust, in the last, we added the oil degrading strains-compost contaminated soil. Result: The oil removal rates were determinated by gravimetric method. The oil removal rates of control group, oil contaminated soil + compost group and oil contaminated soil + oil degrading strains-compost group were 23.4%, 31.6% and 49.7% on 60 th day, respectively. Compared with the control group, the oil removal rate of oil contaminated soil + oil degrading strains-compost group increased by 26.3%. Conclusion: The research indicates that oil contaminated soil + oil degrading strains-compost can improve petroleum-degrading rates.
