Abstract
Data were pre-sented revealing that the paucity of growth of certain strains of yeast at 38[degree]C is somehow related to a reduced ability to carry out the biosynthesis of pantothenic acid. Results were discussed in the light of the accepted pathway of pantothenate biosynthesis. Since the organisms are genetically endowed with the enzymic make up to synthesize pantothenate, this provides another example of the fact that environment plays an important role in genetic expression.
