Laplace JM, Delgenes JP, Moletta R & Navarro JM (1993) Cofermentation of glucose and xylose to ethanol by a respiratory-deficient mutant of Saccharomyces cerevisiae co- cultivated with a xylose-fermenting yeast.
Ethanol productionFermentationGlucoseResource efficiencyXyloseFermentation performance of these biomass hydrolysates is limited by the lack of industrially suitable organisms to convert both glucose and xylose efficiently. To resolve this issue, several methods have been suggested, e.g., co‐cultivation of ...

This article reviews current co-culture systems for fermenting mixtures of glucose and xylose to ethanol. Thirty-five co-culture systems that ferment either synthetic glucose and xylose mixture or various biomass hydrolysates are examined. Strain combinations, fermentation modes and conditions, and ferment...

alcoholic fermentation. It was Louis Pasteur, however, who demonstrated that yeast is responsible for the transformation of glucose to ethanol in fermented beverages. He also discovered microorganisms that cause milk to sour, which was later found to be the action of bacteria in lactic acid ...

of glucose. It should be noted that most forms of fermentation besideshomolactic fermentationproduce gas, commonly CO2and/or hydrogen gas. Many of these different types of fermentation pathways are also used in food production and each results in the production of different organic acids, ...
