The Biological Bulletin, 1958 1. Brilliant cresyl blue accumulates in the vacuoles of Desmarestia munda and D. herbacea and the accumulated dye appears purple, indicating that the pH of the vacuolar sap is less than 1.0 or greater than 7.5. However, the expressed saps of these two brown algae have pH 1.0 or less and about 2.0, respectively.
