[Dependence of Bacillus subtilis cell respiration on monovalent cations].

Nigericin, monensin, valinomycin + carbonyl-cyanide-m-chlorophenylhydrazone and gramicidin inhibit the respiration of Bacillus subtilis cells incubated with NAD-dependent substrates or succinate, but not with ascorbate + N,N,N',N'-tetramethyl-p- phenylene-diamine. The level of inhibition was decreased by potassium ions and, in a lower degree, by sodium or… CONTINUE READING
