(Submitter supplied) In this work, three O.oeni strians were inoculated, two of them were of our own collection (3P2 and 2T2) and the other one is the type strain 217T (=ATCC 23279) in WLM-12 to develop MLF in these conditions (Bordas et al, 2015). Basic fermentation characteristics were monitored, such as growth rate and biomass yield, as well as the respective transcriptome. This approach allowed a better understanding of metabolic adaptation and its association with specific genes expression profiles, likewise we were able to identify some biological process directly involved in the fermentation conditions such as pH or ethanol content.

(Submitter supplied) 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).

(Submitter supplied) 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.
