摘要
在获得了一种耐酚能力达９１５ｍｇ／Ｌ的菌种的基础上，进一步研究了以海藻酸钠包埋法制得的该菌种固定化细胞的性能。同时，采用了２种方法，即添加硅藻土和用己二胺－戊二醛对固定化细胞表面进行化学处理，使固定化细胞的机械强度，降酚活性，稳定性均得到了提高。实验证明这２种方法都有令人满意的效果。
Based on a strain of bacteria degrading up to 915mg/L of phenol,the characteristics of the immobilized cells of the strain were further examined.To improve the performance of the immobilized cells for biodegrading phenol toxicants,two methods were studied,i.e. adding diatomaceous earth into sodium alginate gel matrix and surface chemical preparation of the immobilized cells with hexanediamine and glutaric dirldehyde.Results obtained from the experiments demonstrated that the performance induc,such as degradation effect,were greatly improved for the immobilized cells.
