Aflatoxin production by Aspergillus parasiticus in a competitive environment

Aspergillus parasiticus NRRL 2999 was grown in the presence of Rhizopus nigricans, Saccharomyces cerevisiae, Acetobacter aceti, or Brevibacterium linens and aflatoxin concentration was determined after 3,5,7, and 10 days of incubation at 28C. R. nigricans and S. cerevisiae inhibited growth and aflatoxin production by A. parasiticus. B. linens caused slight inhibition and A. aceti stimulated growth and aflatoxin production by A. parasiticus.
