YES medium supported better growth of both the strains and still cultures on this medium yielded the largest levels of kojic acid with both the strains. With the toxigenic strain, still cultures on this medium also produced the maximum amount of aflatoxins. The ratio of aflatoxins B to G and the ratio of aflatoxins in the mycelium to those in the medium were very low in YES medium still cultures. The significance of these data is discussed. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-65-2-243
