摘要：

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 M) at the onset of starvation, and a high affinity system (Km = 0.55 ± 0.15 M) after 168 h of starvation. Both systems had a narrow substrate specificity, and both were osmotic shock-sensitive. © 1990 Federation of European Microbiological Societies.
