Fungal inhibition in four commonly used agar media was improved by substituting natamycin (pimaricin) for cycloheximide. The recovery of bacteria was not affected by natamycin, whereas fungal contamination from a variety of samples was significantly suppressed. Furthermore, natamycin lacks the occupational health hazards of cycloheximide. Medium-dependent natamycin degradation occurred during the preparation and refrigerated storage of agar plates, but the addition of natamycin at 21.6 mug/ml resulted in effective residual activity.
在四种常用的琼脂培养基中,通过用纳他霉素(匹马霉素)替代环己酰亚胺来提高真菌抑制作用。纳他霉素对细菌的回收没有影响,而各种样品的真菌污染则得到了显著抑制。此外,纳他霉素没有环己酰亚胺的职业健康危害。在琼脂平板的制备和冷藏储存过程中,纳他霉素会发生介质依赖性降解,但添加 21.6 微克/毫升的纳他霉素可产生有效的残留活性。
