what is natamycin
Natamycin Natamycin (INN), also known as pimaricin and sometimes sold as Natacyn, is a naturally occurring antifungal agent produced during fermentation by the bacterium Streptomyces natalensis, commonly found in soil. Natamycin has a very low solubility in water; however, natamycin is effective at very low levels. Its minimum inhibitory concentration is less than 10 ppm for most molds. Natamycin is classified as a macrolide polyene antifungal, and as a drug, is used to treat fungal keratitis, an infection of the eye.
