Antifungal Antibiotic Natamycin Powder CAS 7681-93-8
Natamycin is a natural antifungal compound produced by the fermentation of Streptomyces, belonging to polyene macrolides, which can widely and effectively inhibit the growth of various molds and yeasts, as well as the production of mycotoxins, and can be widely used in food preservative preservation and antifungal treatment.
Natamycin is used to treat fungal infections, including candida, Aspergillus and Fusarium. It is also used as eye drops or oral medicine, where the body absorbs less natamycin. When taken orally, little is absorbed from the gastrointestinal tract, making it unsuitable for use as a systemic agent. Natamycin is also used in eye drops, and its 5% natamycin content is suitable for the treatment of bacterial blepharitis, conjunctivitis and keratitis caused by microorganisms, including Fusarium sapropium keratitis.
