双乙酸钠抑制产黄青霉菌的效果观察

The Effect of Sodium Diacetate on the Inhibition of Pen. Chrysogenum

用PDA培养基于32℃培养时,当下述防霉剂浓度皆为0.3％,SDA比丙酸钙、山梨酸钾和苯甲酸钠对产黄青霉菌有更好的抑制效果;SDA抑制产黄青霉菌的适宜浓度为0.1％～0.2％。

It was found that the effect of sodium diacetate on the inhibition of pen. Chrysogem in PDA culture is better than cakium propiorate. Potassium sobate and sodium benzoate when their councentration is 0.3%. The preper concentration of sodium diacetate is 0.1%-0.2%.
