Dehydration stress responses of yeasts Torulaspora delbrueckii, Metschnikowia pulcherrima and Lachancea thermotolerans: Effects of glutathione and trehalose biosynthesis

In food industry and winemaking, the use of active dehydrated yeast (ADY) Saccharomyces cerevisiae is a frequent practice because of the long-term stability and high efficiency of ADY. Nowadays, there is an increasing interest for new yeasts strains, such as Torulaspora delbrueckii (Td), Metschnikowia pulcherrima (Mp) and Lachancea thermotolerans (Lt). However, the yeasts transformation processes into the solidified form generate several...
