Natamycin

Natamycin is a naturally occurring anti-mycotic product that is classified as a polyene macrolide and can be produced through fermentation by Streptomyces spp. Natamycin not only broadly and highly effectively inhibits the growth of various molds and yeasts, but also inhibits the production of their toxins. Natamycin can be widely used in food preservation and as an anti-fungal treatment. Natamycin has no effect on bacteria, so Natamycin does not inhibit the natural maturing processes of yogurt, cheese, or fresh ham.Natamycin has 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.
