There are errors in the published article. In the Abstract FLO11p should be replaced by Flo11p, and ∆flo11 should be replaced by flo11 mutant. In the section entitled “Cell surface charge variation of 3238-32 and the flo11 mutant in minimal medium at 222 different pHs” 3238∆flo11 should be replaced by 3238-32∆flo11.
