MLF plays an important role in determining the final quality of wines[1]. Even though this LAB is naturally present in musts, wines and oenological environment, spontaneous MLF are usually unpredictable because of the stressful conditions and especially due to acidity [2]. The consequence of the mismanagement ofthis step might lead to the depreciation of wine quality. To obtain a clone more tolerant to acidity, we undertaken to replicate O. oeni in a temporally varying environment (pH 5.3 to 3.2) to improve acid tolerance. To discriminate stress tolerance of evaluated populationsversus parental strain an ethanol or acid stress were improved to both population. %G English %2 https://institut-agro-dijon.hal.science/hal-03150712/document %2 https://institut-agro-dijon.hal.science/hal-03150712/file/Poster%20LAB12_FJ.pdf %L hal-03150712 %U https://institut-agro-dijon.hal.science/hal-03150712 %~ UNIV-BOURGOGNE %~ PAM %~ AGREENIUM %~ AGROSUP-DIJON %~ INSTITUT-AGRO-DIJON %~ INSTITUT-AGRO-DIJON-PAM %~ INSTITUT-AGRO-PAM
