| na+ modulates the k+ permeability and the membrane potential of alkalophilic bacillus. | in the absence of na+ in the medium, the membrane potential of obligately alkalophilic bacillus cells was found to be decreased by the addition of k+ to the medium, whereas k+ addition in the presence of na+ had no effect. rb+ showed essentially the same effect as k+. the decreased membrane potential was quickly restored by lowering the k+ concentration in the medium or by adding na+ or li+ to the medium. thus, in the absence of na+, the membrane potential of alkalophilic bacillus seems to be af ... | 1987 | 3663674 |

| analysis of 16s-23s rrna intergenic spacer regions of vibrio cholerae and vibrio mimicus. | vibrio cholerae identification based on molecular sequence data has been hampered by a lack of sequence variation from the closely related vibrio mimicus. the two species share many genes coding for proteins, such as ctxab, and show almost identical 16s dna coding for rrna (rdna) sequences. primers targeting conserved sequences flanking the 3' end of the 16s and the 5' end of the 23s rdnas were used to amplify the 16s-23s rrna intergenic spacer regions of v. cholerae and v. mimicus. two major (c ... | 1999 | 10224020 |
