Exoenzymes of Wine Microorganismsesterases, lipases, tannases, phenoloxidases). The individual members of the wine microflora display their specific enzyme spectrum at different stages of vinification. Glucanases and phenoloxidases produced by .as part of the grape infection process may enter the must and alter its composition. Pol

Physical and Chemical Stress Factors in Yeastons. These include the general stress response (GSR) resulting in trehalose accumulation, the high osmolarity glycerol (HOG) pathway producing glycerol as a compatible solute and the cell wall integrity pathway (CWI) to provide surface stability. Physical stresses such as temperature variations and

However, the interactions of lactic acid bacteria with yeast have to be considered to master this fermentation process. The cumulative effect of these multiples stressesincreases the limitation for bacterial

Influence of Phenolic Compounds and Tannins on Wine-Related Microorganismsts of the grape, although typically only 20-30 polyphenols are identified in grapes and must using standard analytical methods, such as HPLC/UV-Vis. The biosynthesis of these compounds follows the route: the shikimic acid, the phenylpropanoid, and the flavonoid pathway. The products of these pathway

The cumulative effect of these multiples stressesincreases the limitation for bacterial growth..Several adaptative mechanisms at the genetical and physiological levels are implied for bacterial development and adaptation in wine. Some of them are discussed in this chapter.
