Abstract
When cells of selected Kluyveromyces strains were aerobically propagated in
batch culture with glucose, cell growth, oxygen uptake and ethanol production exhibited
differential responses to the respiratory inhibitor, antimycin A. Even within the species
Kluyveromyces lactis (sensu Vaughan-Martini and Martini), which was previously thought
to be genetically homogeneous, metabolic heterogeneity was observed among the type
strains, representing the four formerly different species now grouped with the epithet K.
lactis. Results of this study support the concept of physiological biodiversity within the
species K. lactis, and suggest that expression of the Crabtree effect is more highly variable
in these yeasts than previously thought.
