Project description:The correct development of malolactic fermentation depends on the capacity of Oenococcus oeni to survive under harsh wine conditions. The presence of ethanol is one of the most stressful factors affecting O. oeni performance. In this study, the effect of ethanol addition (12% vol/vol) on O. oeni PSU-1 has been evaluated using a transcriptomic approach.
Project description:The correct development of malolactic fermentation depends on the capacity of Oenococcus oeni to survive under harsh wine conditions. In this study it was characterized the transcriptomic response of O. oeni PSU-1 during the adaptation to wine-like medium (WLM). The period evaluated was from the inoculation into WLM (12% v/v pH 3.4) until the beginning of malolactic fermentation (8h after inoculation).
