Strain differences, lactic cultures

In the same way, various strains belonging to aU of the species of the FOEB (Faculle d Oenologie de Bordeaux) collection and isolated in wine were tested to look for possible reactions. Several associations were clearly demonstrated to create reactions in the liquid medium. The most obvious effects were recorded for P. pentosaceus and L. plantarum, both strongly inhibiting the growth of O. oeni and L. mesenteroides. This inhibition not only exists in mixed cultures but also when a culture medium pre-fermented by these two strains is added to O. oeni culture medium (Lonvaud-Eunel and Joyeux, 1993). Different experiments have permitted the characterization of the possible roles of hydrogen peroxide, pH and lactic acid. For two strains, the inhibitory molecnles which... [Pg.178]
