Extracts of Penicillium commune, a fungus isolated from cottonseed, showed biological activity in day-old cockerels. Two neurotoxic metabolites were isolated and identified as penitrem A and roquefortine. This is the first report of roquefortine being produced by a fungus other than Penicillium roqueforti as well as the first report of penitrem A and roquefortine being produced in the same culture. Production of these toxins on liquid media and cottonseed was determined.
