Microorganisms and the Biological Cycling of Selenium

摘要: Most studies on the microbial transformations of elements have emphasized nutrient cycling within biosphere or economics agricultural industrial processes. Cyclic between soluble, insoluble, and gaseous forms carbon, nitrogen, hydrogen, oxygen, sulfur are well known. Recently, attention has been focused role microorganisms in production degradation chemicals containing toxic (Alexander, 1973; Wood, 1974). Measures to increase animal food crop disposal waste materials can result introduction amounts harmful terrestrial aquatic ecosystems. Many their compounds vary widely both toxicity mobility. Consequently, safe effective recycling requires an understanding potential toxicities possible environment.
