in order to study the effect of phi and pho on k efflux , cc cells were incubated with 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid ( 150 microm ) and acetazolamide ( 1 mm ) at different phi ( 6.7 , 7.3 , and 7.8 ) , and resuspended in media with different pho ( 6.75 , 7.4 , and 8 ) : k efflux was stimulated by reducing phi but was independent of pho .
