Abstract
The microbial degradation of a number of 14C-labeled, recalcitrant, aromatic pollutants, including trichloroguaiacol and di-, tri-, and pentachlorophenol, was investigated in aquatic model systems in the laboratory. Natural, mixed cultures of microorganisms in the water from a brown-water lake with a high content of humic compounds mineralized all of the tested substances to a higher degree than did microorganisms in the water from a clear-water lake. Dichlorophenol was the most rapidly degraded pollutant.
摘要
在实验室的水生模型系统中，研究了多种14C标记的难降解芳香族污染物的微生物降解情况，这些污染物包括三氯愈创木酚、二氯苯酚、三氯苯酚和五氯苯酚。来自富含腐殖化合物的褐水湖水中的天然混合微生物培养物，比来自清水湖水中的微生物能将所有测试物质矿化到更高程度。二氯苯酚是降解最快的污染物。
