title: Bacteriophages recovery from raw sewage of different texture.
abstract: Bacteriophages recovery was enhanced by the addition of Mg2+ divalent cation or when the raw sewage filtrate was adjusted to pH 4.5. On the other hand, when Mg2+ or Ca2+ divalent cations were added to the acidified sewage filtrate, all sensitive phase species were found to be phage-resistant.
