Les énergies non-renouvelables ont été d’un apport capital dans l’industrialisation et l’urbanisation dans les derniers centenaires. L’exploitation excessive des réserves d’hydrocarbures et son impact environnemental ont contribué au developpement de plusieurs technologies durables à caractère néo-carbone neutre. A cet effet, les processus biologiques comme la fermentation pourraient être exploités pour convertir biologiquement le hydrates de carbone en énergies comme l’hydrogène (H2) ou des acides organiques commercialement rentables.

Thesis (MScAgric)--University of Stellenbosch, 2000.<br>ENGLISH ABSTRACT: The quality of wine is influenced by numerous factors. These factors include the quality of the grapes, winemaking techniques and quality control throughout the winemaking process. It is thus very important that any process leading to the lowering of the quality of the wine be prevented. Evidence in the wine industry shows that bacterial spoilage is still very much a common problem in many wineries. The spoilage of wine by bacteria can lead to amongst other problems, elevated volatile acidity levels, of which only

Abstract:

Thesis (MTech (Chemical Engineering))--Cape Peninsula University of Technology, 2016.<br>Grape producers and wine makers in South Africa are currently affected by various challenges, which include anti-alcohol lobbies, climate change, over-production in some vintages and the lack of transformation including empowerment in certain sectors of the industry. Climate change and global warming lead to poor quality wine grapes and as a result, poor quality wine. Therefore, there is a need to channel grapes away from normal wine production and provide an alternative source of income for the industry.

Abstract:

La fermentation du cacao est une fermentation spontanée qui dure de 4 à 8 jours et repose principalement sur la succession de trois groupes de microorganismes : les levures, les bactéries lactiques et les bactéries acétiques qui réalisent les fermentations alcoolique, lactique et acétique respectivement. Les fèves saines sont stériles jusqu’à l’ouverture de la cabosse. L’inoculation des fèves est réalisée le plus souvent naturellement à l’aide de l’environnement autour de l’écabossage et de la mise en fermentation.

The metabolic pathways in S. cerevisiae during fermentation of Icewine grape must have not been studied and the transcriptional response of this yeast to sugar stress has not been investigated. Global transcriptional analyses showed that the transcription of 589 genes in S. cerevisiae was affected more than two-fold in grape juice containing 40% (w/v) sugars. High sugar stress up-regulated the glycolytic and pentose phosphate pathway genes. Gene expression profiles indicate that the oxidative and non-oxidative branches of the pentose phosphate pathway were up-regulated and might be used
