Major limitations have been reported during in vivo flavor release studies, such as marked intra- and inter-individual variability. To overcome these limitations, a chewing simulator has been developed to mimic the human mastication of food samples. The device faithfully reproduces most of the functions of the human mouth. The active cell comprises several mobile parts that can accurately reproduce shear and comp…

Stress Responses of Oenococcus oeni

2011

Oenococcus oeni is an alcohol-tolerant, acidophilic lactic acid bacterium responsible for malolactic fermention in wine. The stress responses of O. oeni have been studied at both the molecular and physiological levels. Genes encoding stress proteins mainly belong to the CtsR regulon. Other regulation mechanisms seem to coexist in O. oeni and may correspond to posttranscriptional regulation. Maintenance of the cell membrane integrity under stress conditions seems to be a prerequisite for survival in wine. The active cell response to protect membrane function under stress conditions requires changes in fatty acid composition and involves stress proteins. Various solute transporters and energy…
