The Effects of Washing Treatments on the Composition of Staphylococcus Aureus

Abstract

Cells of Staphylococcus aureU8 grown in a medium of water activity (aw) 0·993 were washed in water and in solutions of sucrose, glycerol, NaCl, KC1, NH4Cl, and MgS04 of 0·993 aw? Retention of sodium and potassium and loss of ultravioletabsorbing compounds were measured. Retention of sodium was greatest after washing in water or in glycerol solution, while potassium and ultraviolet-absorbing compounds were largely retained in all of the washing treatments
