Production of SO₂ and SO₂ binding compounds by Saccharomyces cerevisiae during the alcoholic fermentation and the impact on wine lactic acid bacteria

Creator:

O'Neil, Allison L.

Abstract:

Malolactic fermentation (MLF) is important in the production of wines as it reduces acidity through the conversion of malic acid to lactic acid. However, successful MLF can be difficult to achieve due to yeast antagonism of the bacterium responsible for the secondary fermentation, Oenococcus oeni. In particular, yeast produced sulfur...

Impact of weak and strong acids on the destruction of lactic acid bacteria during high pressure processing

Creator:

Sarangapani, Rama Krishna

Abstract:

High hydrostatic pressure (HHP) affects the pH of weak acids due to an increased degree of acid dissociation while under pressure. The temporary pH reduction by high pressure in such a case may influence the barotolerance of microorganisms. The objective of this study was to determine the impact of weak...
