An agar diffusion bioassay was used to compare the sensitivities of bacteria to the mycotoxin beauvericin. Bacillus pumilus LACB101 was inhibited by filter-paper disks containing 0.1  g of beauvericin; B. cereus, B. mycoides, B. sphaericus, Paenibacillus alvei, P. azotofixans, P. macquariensis, and P. pulvifaciens by 1 g; and P. validus by 25 g. The anaerobes Eubacterium biforme, Peptostreptococcus anaerobius, P. productus, Bifidobacterium adolescentis, and Clostridium perfringens were also inhibited by beauvericin. |
