RESUMO
The role for the gene encoding glycerol 3-phosphate dehydrogenase (DhGPD1) from the osmotolerant yeast Debaryomyces hansenii, in glycerol production and halotolerance, was studied through its heterologous expression in a Saccharomyces cerevisiae strain deficient in glycerol synthesis (gpd1Delta). The expression of the DhGPD1 gene in the gpd1Delta background restored glycerol production and halotolerance to wild type levels, corroborating its role in the salt-induced production of glycerol. Although the gene was functional in S. cerevisiae, its heterologous expression was not efficient, suggesting that the regulatory mechanism may not be shared by these two yeasts.
