Summary: | Lactic acid bacteria isolated from dairy products, vegetables and fruits were screened for their antifungal and antimycotoxigenic activities. From 420 isolates tested, four isolates were found to be inhibitory to four
Penicilliumspecies. Two of the lactic acid bacteria isolates showed the largest inhibitory activity against
Penicillum citrinumand
Penicillium expansum. The two isolates were identified as
Lactobacillus caseispecies. Production of patulin and citrinin was also inhibited in the presence of the
Lactobacillisupernatants. The inhibitory activity in the two
Lactobacillicell-free supernatants was shown to be unrelated to the production of lactic acid or hydrogen peroxide, and was found to be sensitive to proteolytic enzymes and to high temperature (100 °C). The antimycotoxigenic activity was not affected by the addition of glucose used by
Lactobacillispecies during incubation. |
