Abstract
- Malolactic fermentation (MLF) is carried out by Oenococcus oeni under very harsh conditions. This paper shows that stress compounds in wine such as SO(2), fatty acids and copper have an inhibitory effect on cell growth and MLF duration, and relates this effect to an inhibition of ATPase activity. Of the stress compounds, SO(2) and dodecanoic acid had the strongest effect, decreasing the ATPase specific activity to 37% and 58%, respectively. It can be concluded that ATPase is a good indicator of the physiological state of the cells and their ability to lead MLF.
