Application Notes
Amphotericin B is a polyene antimycotic derived from Streptomyces nodosus. Its mode of action is to disrupt the osmosis of the cell membrane by binding to fungal and bacterial ergosterols causing intercellular potassium and magnesium to leak out of target cells.2-4 Amphotericin B is effective against many fungi, yeasts and molds, e.g., Absidia spp., Aspergillus spp., Basidiobolus spp., Candida spp., etc.2

Minimum inhibitory concentration (MIC) of amphotericin B has been reported for many fungi, yeasts and molds. MIC for Candida spp. range from 0.1 to 2 mg/L, Aspergillus niger is 1 mg/L, Fusarium sp. is 1 to greater than 4 mg/L, Bipolaris sp. is 0.5 to 1 mg/L, etc.4
