✦ Synopsis
A study was made to determine whether Aspergillusflavus (QM 380; NRRL 3537; ATCC 9643) and Aspergillus versicolor (QM 432; NRRL 573; ATCC 16,020), mold strains routinely combined in fungus resistance tests for United States military specification (MIL-STD-810B; MIL-STD-331A), were capable of producing aflatoxins or sterigmatocystin when grown separately or in mixed culture fermentations of cracked corn (11 days at25 ~ C or 28 ~ C). Substantial quantities of sterigmatocystin (average of 3 replicates ----1,895 ppb) were detected when A. versicolor was the sole colonist. No sterigmatocystin was detected when A. versieolor was simultaneously inoculated with other molds. Aflatoxins were not detected in any of the treatment combinations.
