Abstract

34 yeast strains representing 22 species and two varieties were investigated for the existence of a proton-sugar symport. The changes in pH of unbuffered cell suspensions on the addition of alkali, acid, transportable sugars and uncouplers were recorded. Responses indicating the existence of an energy dependent proton extrusion and H+-sugar symport were found in most cases, particularly in Rhodotorula but rarely in Saccharomyces species. Remarkable differences were found among strains belonging to the same species.
