Fermaflavones are the isoflavone co-products isolated from soy-based industrial fermentations. Isoflavones such as genistein and daidzein can be marketed and sold as nutrional supplements to add value to your soy-based erythromycin or other industrial fermentation process. Fermaflavones improve the economics of a soy-based manufacturing process. For example, a medium sized industrial fermentor (100,000L) can readily generate 5.5 kg of purified genistein plus daidzein depending on the amount of soybean meal added to the medium. Fermaflavones can be harvested before or after the fermentation, so neither method requires modification of the erythromycin producing organism or the manfacturing process.
