Riassunto

Il cell-wall diStaphylococcus aureus è capace di legare cationi. Poichè la capacità legante ioni dipende dal pH del mezzo, si è studiata la capacità legante idrogenioni di cell-wall liofilizzato isolato daS. aureus. Titolazioni al di sotto di pH 9.0 hanno dimostrato la presenza di 3 siti leganti con pK rispettivamente di 7,15, 4,70 e 3,19 e capacità massima legante di 2, 28 e 232 ώ-equiv. /g (peso secco cell-wall). Viene discussa la natura chimica dei gruppi dissociabili.
