Abstract
Na+ was found to be essential for the accumulation of sucrose by Vibrio alginolyticus. Sucrose uptake was completely inhibited by the addition of proton conductor at neutral pH, but not at alkaline pH, where the primary electrogenic Na+ pump generates the Na+ electrochemical gradient. We therefore conclude that sucrose transport is driven by the electrochemical potential of Na+ in this organism.
摘要
已发现钠离子对于溶藻弧菌积累蔗糖至关重要。在中性pH值下添加质子导体可完全抑制蔗糖摄取，但在碱性pH值下则不然，此时主要的生电钠泵会产生钠离子电化学梯度。因此，我们得出结论，在这种生物体中，蔗糖转运是由钠离子的电化学势驱动的。
