SUGAR TRANSPORT IN A PSYCHROPHILIC YEAST.
Cirillo, Vincent P. (Seton Hall College of Medicine and Dentistry, Jersey City, N.J.), Peter O. Wilkins, and Joseph Anton. Sugar transport in a psychrophilic yeast. J. Bacteriol. 86:1259-1264. 1963.-The mechanism and temperature characteristic for sugar transport were compared in a psychrophilic and a mesophilic yeast. Between 0 and 10 C, glucose utilization, glucosamine accumulation, and sorbose transport showed a very high temperature characteristic in the mesophile (mu = 50,000) compared with the psychrophile (mu = 12,000). Hexokinase activity in cell-free extracts from both yeasts, however, showed the same low temperature characteristic (mu = 15,000). Although the temperature characteristic for sugar transport was markedly different for the mesophile and the psychrophile, sugar transport in both yeasts met the criteria for carrier-mediated facilitated diffusion.
