Possible Interaction: Galactose and Glycerol

“ Glycerol and dihydroxyacetone decreased 2- to 3-fold the derepression observed in ethanol or galactose but did not affect invertase derepression.”

“As part of a study on the effect of low temperature on cellular regulatory processes, a class of lactose-negative mutants of Escherichia coli … mutants functioned normally at 20 C. Galactose exhibited a strong inhibitory effect on growth, especially at 20 C. Growth of the mutants on glycerol … galactose ….”
