Removal of dibenzofuran, dibenzo-p-dioxin, and 2-chlorodibenzo-p-dioxin (2-CDD) (10 ppm each) from soil microcosms to final concentrations in the parts-per-billion range was affected by the addition of Sphingomonas sp. strain RW1. Rates and extents of removal were influenced by the density of RW1 organisms. For 2-CDD, the rate of removal was dependent on the content of soil organic matter (SOM), with half-life values ranging from 5.8 h (0% SOM) to 26.3 h (5.5% SOM).
从土壤微观环境中去除二苯并呋喃、二苯并 - 对 - 二恶英和2 - 氯二苯并 - 对 - 二恶英(2 - CDD)(每种浓度为10 ppm)至十亿分率范围内的最终浓度,受到鞘氨醇单胞菌属菌株RW1添加的影响。去除速率和程度受RW1生物体密度的影响。对于2 - CDD,去除速率取决于土壤有机质(SOM)的含量,半衰期值范围从5.8小时(0% SOM)至26.3小时(5.5% SOM)。
