摘要：

The maximal growth rate of the marine cyanobacterium Oscillatoria brevis was reached at 200-400 mM NaCl and pH 9.0-9.6. NaCl was found (i) to stimulate the rate of the light-supported ΔΨ generation across the cytoplasmic membrane of the cells and (ii) to decrease the sensitivity of ΔΨ level and motility of the O. brevis trichomes to protonophorous uncouplers. The Na+/H+ antiporter, monensin, increased both ΔΨ and the uncoupler sensitivity of the cells. The data obtained agree with the assumption that O. brevis possesses a primary Na+ pump in its cytoplasmic membrane. © 1990 Springer-Verlag.
