摘要
用海藻酸钠作为载体将一株降酚菌株进行固定化包埋.利用正交实验确定了该菌株固定化细胞制备的最优条件.研究表明,该降酚菌株的固定化细胞对苯酚的降解能力和耐受能力均大于游离细胞.降酚菌株固定化细胞降解苯酚的最适温度范围是30~35℃,最适pH值范围为6~8.该菌株的固定化细胞对废水中的COD也具有良好的降解效果.
In this work, one strain of phenol-degrading was immobilized in sodium alginate. Optimal preparation condition of the strain immobilization is carried out by the cross-test experiments. The results show that the degradation efficiency of immobilized cells is apparently superior to that of free cells, and the optimal temperature of degrading phenol is 30~35℃ , the optimal pH value is 6 - 8. The immobilized cells have good performance of degrading COD in wastewater.
