The effect of sodium novobiocin on Act. levoris, strain LIA 0868 producing levorin and levoristatin was studied. High lethal effect of the antibiotic on Act. levoris was found. The effect increased with a rise in the antibiotic concentration in the agar from 2 to 6 lambda/ml. The inhibitory effect of novobiocin on Act, levoris was evident from a marked increase in the number of morphologically changed colonies with a low level of levorin production. The selective effect of novobiocin on the organism producing levorin and levoristatin was evident from selection of variants with high levels of levoristatin production on media containing novobiocin.
研究了新生霉素钠对产生左菌素和左菌素他汀的左旋放线菌LIA 0868菌株的作用。发现该抗生素对左旋放线菌有很高的致死作用。随着琼脂中抗生素浓度从2微克/毫升增加到6微克/毫升,这种作用增强。新生霉素对左旋放线菌的抑制作用从形态改变的菌落数量显著增加以及左菌素产生水平较低中明显可见。新生霉素对产生左菌素和左菌素他汀的生物体的选择作用从在含有新生霉素的培养基上选择左菌素他汀产生水平高的变体中明显可见。
