[Use of flour from sunflower oil cake in the biosynthesis of antigungal antibiotics].
The possibility of replacing soybean meal and corn-steep liquor by food wastes of the oilpress industry and the meal of the sunflower oil cake in particular is discussed as applied to the fermentation media for production of antifungal antibiotics, such as levorin, mycoheptin, amphotericin. The studies showed that replacement of soybean meal by sunflower oil cake meal with simultaneous increasing of the amount of carbohydrates in the medium increased the levorin levels by 60--70 per cent as compared to the media used at present. When soybean meal and corn-steep liquor were simultaneously replaced by sunflower oil cake meal in amounts of 3--4 per cent the levels of mycoheptin in the fermentation broth increased by 30--65 per cent respectively. Replacement of soybean meal and corn-steep liquor by 3 per cent of sunflow oil cake meal in the medium used presently increased the amphotericin levels by 27 percent as compared to the control. Therefore, sunflower oil cake meal is a substitute of full value for soybean meal and corn-steep liquor in the fermentation media for production of antifungal antibiotics.
