复配抑菌剂对假单胞杆菌抑制效果的研究

Study on the bacteriostatic effect of multiple antimicrobials on Pseudomonas spp

  • 摘要: 在单因素实验的基础上,运用响应面法优化了丁香酚、异硫氰酸烯丙酯、双乙酸钠、壳聚糖4种抑菌剂复配后对假单胞杆菌的抑制效果。结果表明复配抑菌剂最优浓度为:丁香酚0.51g/L、异硫氰酸烯丙酯0.32g/L、双乙酸钠2.24g/L、壳聚糖0.52g/L,在此条件下抑菌率实测值为85.37%,测得最低抑菌浓度为2.59g/L。在此浓度基础上复配抑菌剂对假单胞杆菌的抑菌圈直径达到26.5mm,明显高于茶多酚和苯甲酸钠,表明对假单胞菌杆菌有明显的抑制作用。 

     

    Abstract: Based on the single-factor experiments, the responses surface methodology (RSM) were applied to study the effect of eugenol, allylisothiocyanate, sodiumdiacetate, chitosan on the Pseudomonas spp. The result showed that the optimal concentration of ugenol, allylisothiocyanate, sodiumdiacetate, chitosan was 0.51, 0.32, 2. 24, 0. 52g / L, respectively. At this condition the bacteriostatic rate was 85. 37 %, the minimum inhibitory concentration was 2. 59g / L. And the diameter of inhibitionzone was 26. 5mm, significantly higher than the polyphenols and sodium benzoate, the inhibitory effect on the Pseudomonas spp was distinctly.
