Abstract:
The uptake kinetics of D-glucose were examined in the marine Vibrio sp. S14 during a period of 168 h of complete energy and nutrient starvation. Two glucose transport systems were distinguished in Vibrio sp. S14: a low affinity system (Km = 4.6 +/- 0.9 microM) at the onset of starvation, and a high affinity system (Km = 0.55 +/- 0.15 microM) after 168 h of starvation. Both systems had a narrow substrate specificity, and both were osmotic shock-sensitive.
