摘 要:借助生物活性测定法和高效液相色谱法对发酵液中农用抗生素进行追踪监测,探讨了大孔吸附树脂对菌株TJ430发酵液中农用抗生素的分离纯化条件。经过对比试验发现D-101型大孔吸附树脂的吸附性能最好;最佳吸附时间为120 min;70%丙酮水溶液的解吸附能力最佳;最佳解吸附pH为接近中性条件;最佳解吸附时间为120min。采用D-101型大孔吸附树脂对TJ430菌株发酵液中抗生素进行吸附,在中性条件下经70%丙酮水解吸附,使发酵液中抗生素得到了有效的分离纯化。An agro-antibiotic extract was obtained by bioassay and HPLC. The dynamic adsorption performance of macroporous resin D-101 on the agro-antibiotic from the Streptomyces strain TJ430 fermentation broth was inves tigated. The influences of the adsorption and desorption time, value of pH, and concentration of acetone eluent on extraction were discussed. The results showed that D-101 resin had good adsorption ability for fermentation broth, and the optimum adsorption and desorption conditions were as follows: the adsorption and desorption time was 120 minutes, the desorption concentration of acetone was 70%, and the pH value of desorption was 6.0. The antibiotic was refined efficiently after adsorption and desorption procedure.
