| 释义 | bioremediation noun[ U ] environment specializeduk /ˌbaɪ.əʊ.rɪ.miː.diˈeɪ.ʃən/ us /ˌbaɪ.oʊ.rɪ.miː.diˈeɪ.ʃən/ a method of cleaning up pollution from oil, poisons, waste, etc. using bacteria or other small organisms that break down the substance : Bioremediation has been used in high-profile cleanups, including oil spilled from the well fires off the coast of Kuwait after the 1991 Persian Gulf War. Researchers devised a bioremediation system that electrically stimulates bacteria to break down toxic chemicals in the environment. The contaminated soil was excavated and mixed with straw and wood chips, which help promote the bioremediation process.

The topics covered include discussion of technology transfer issues, bioremediation of chlorinated volatile organic compounds, and alkylbenzene and polycyclic aromatic hydrocarbons. One major aspect of this work focused on determining how temperature affects bioremediation of diesel-contaminated sites. Field measured bioremediation rates in a cold region landfarm: spatial variability relationships. Fundamental discussions of metal(loid) bioavailability and microbial transformations accompany applied topics like bioremediation and soil applications of metal-containing wastes. From an economic standpoint, a process that utilizes only a minimal amount of electric energy would vastly improve the use of bioremediation in such areas. Although bioremediation is very much an established methodology in temperate regions, several important issues have emerged concerning the application of the technology in freezing ground. It is the realm of bioremediation where the greatest advances are being made for treating petroleum-contaminated soils in cold regions. It was found that irrigation can substantially improve the distribution of nitrogen, thereby increasing bioremediation rates and shortening treatment times by as much as 50%. A cost-effective process based on passive solar soil heating is proposed to raise the soil temperature and thereby improve the bioremediation rate. These include new chapters on bioremediation, soil molecular biology, biodiversity, climate change, physiology and ecology, complementing the previous, updated, chapters. Consequently, it is necessary to develop strategies for an improvement of bioremediation performance in cold climates. The potential for bioremediation of acidic wastewaters contaminated with toxic organic compounds and heavy metals. In the meanwhile, the potential for bioremediation has been demonstrated, while biotechnologists have learnt how to modify many organisms in the service of man. However, microbial growth was not clearly improved in the presence of bioremediation agents. These examples are from corpora and from sources on the web.
