A survey of fungi from the order Melanconiales for antibiotic activity

Twenty-six genera including 55 different species of fungi from the order Melanconiales were tested for antibiotic activity. A comparison of the value of four broth substrates used in this survey is given. Twenty-three species were found to be active. More species were found to be active against Pseudomonas aeruginosa than any other test organism used. None of the molds was found to be active against Bacillus subtilis or Escherichia coli.
