| pubmed-article:122081 | pubmed:abstractText | More than 80% of the hexachlorophene added to a Bacillus subtilis culture binds to the cells. Complete growth inhibition requires 6 x 10(5) molecules bound per cell. In contrast, more than 99% decanoate remains in solution and 3.8 x 10(7) molecules bound per cell are needed to inhibit growth. Centrifugation and resuspension of cells in growth medium removes only decanoate, whereas the addition of 1% bovine serum albumin to the growth medium removes both inhibitors from their binding sites on the cells. The addition of untreated cells to a hexachlorophene-treated culture enables the hexachlorophene molecules to redistribute among all the cells with the result that the inhibited cells can resume growth. | lld:pubmed |
