Abstract
Alkalinization of culture medium is accompanied by a considerable incr ease in the putrescine production by Escherichia coli and its efflux i n the environment. Existence of the reversible putrescine (+2)/2K(+) e xchange was shown under conditions of inhibition and energy limitation of the main potassium transport systems. It is assumed that this exch ange serves as an alternative mechanism of potassium transport for pro viding continuous functioning of K+/H+ antiporter.
