The effect of anions on K+-binding in aHalobacterium species

Trinitrocresolate (TNC) at a concentration of 2×10−3 m brings about rapid loss of K from starvingHalobacterium cells. Higher concentrations of other anions such as salicylate, thiocyanate, and perchlorate produce a similar effect. The TNC-induced K loss is not significantly reversed when TNC is removed from the ambient medium. The rate of K loss in the… (More)
