1. The seven bacterial viruses of the T group, active against E. coli, are much more rapidly inactivated by heat when suspended in 0.1 N solutions of sodium salts than when suspended in broth. 2. The kinetics of this inactivation whether in salt solutions or in broth are those of a first order reaction. 3. The rate of inactivation of phage T5 in 0.1 N NaCl at 37°C. can be greatly decreased by the addition of 10–8 M concentrations of such divalent cations as Ca, Mg, Ba, Sr, Mn, Co, Ni, Zn, Cd…

It is concluded that in addition to being an adsorption cofactor, magnesium functions at some late stage in phage development.

The Influence of Inorganic Ions on the Heat Stability of a Thermophilic Bacteriophage

A thermophilic bacteriophage was isolated from soil. Heat inactivation of this phage, suspended in tryptone starch broth at 65°C and 70°C, was found to be a monomolecular reaction. The phage was more

Evidence is provided of the occurrence of such combination and of the properties of the combined phage.

Influence of ionic strength on the stability of phage t2r to osmotic shock

Study of osmotic shock by glycerol in media of different ionic strengths showed that, as the ionic strength increases, the bacteriophage is at first destabihized by the action of the released polyamines and that only when the Ionic strength is raised still further, it is restabilization by the influence of the ionics strength on the resistance of the membrane.

Protection of bacteriophage against x-rays by high concentrations of a neutral salt.

Protection of bacteriophage T1 against x-rays was tested in the presence of concentrations of (NH4)2SO4 ranging from 10–6 M to saturation (4.26 M). Survival of T1 in concentrations of 10–6 to 10–3 M
