Fig 1. Phenotype comparisons for A. flavus strains AF70 and NRRL 3357.

Fig 1

A) After 6 days growth on YGT media, S-morphotype AF70, left, demonstrated several rings of pigmentation correlating with production of numerous small sclerotia, with unpigmented hyphae in the outermost edges of growth. Conversely, L-morphotype NRRL 3357 maintains typical olive-green pigmentation with no sclerotia visible. B) Spore production on two media types, V8 and YGT showed NRRL 3357 consistently producing more spores. C) HPLC quantification of aflatoxin AFB production shows higher concentrations produced by S-morphotype AF70. Student’s t-test where P ≤ 0.05 indicated by asterisk (*).
