| 摘 要： | 用一株外源降解菌进行固定化降解蒽的研究。结果表明其降解蒽的最适温度和pH值为30℃和7。经海藻酸钙固定化包埋后,其降解蒽的能力明显提高,在100mg/L的初始浓度下其降解率在12d达到86%。在固定化颗粒中加入少量硅藻土细粉可以提高菌株对蒽的降解能力。

| Abstract: | An exogenous degrading bacterium was immobilized in calcium alginate to improve the degradation of anthracene. The biodegradation rate of anthracene can reach 86% after 12 days in an initial concentration 100mg/L, with optimum pH and temperature of 7 and 30℃. Experiment indicated that the capability of degradation can be improved by adding some diatomite powder to immobilized cells. |
