Biotechnological studies on the antifungal activity of lactic acid bacteria

Abstract
the other LAB strains with the proteolytic enzymes did not result any changes of the antifungal activity. This indicating that the antifungal substance produced was not bacteriocin or has a proteinaceous activator. Also, it was observed that the treatment of cell-free supernatants of all LAB strains with catalase enzyme did not result any changes of the antifungal activity. This is indicating that the hydrogen peroxide did not account for the observed inhibition.
4. The effect of Surfactants: Almost all the surfactants used had no effect on the antifungal activity of the cell-free supernatant of the tested LAB strains in the concentrations used except the effect of Sodium Dodecyl Sulphate (SDS). As the SDS has stimulatory effect to the antifungal activity of the cells-free supernatant of the LAB strains against A. flavus and A. parasiticus.
