Studies of the Effect of Sodium Azide on Microbic Growth and Respiration: II. The Action of Sodium Azide on Bacterial Catalase.

Studies of the Effect of Sodium Azide on Microbic Growth and Respiration: I. The Action of Sodium Azide on Microbic Growth.

In recent years, publications from this laboratory (Snyder and Lichstein, 1940; Lichstein and Snyder, 1941; Lichstein, 1941) have indicated the value of sodium azide (NaN3) as an aid in the isolation of streptococci from clinical material containing "spreaders" and other interfering gram-negative organisms. The use of blood-infusion agar containing 0.02 per cent sodium azide for the cultivation...

Studies of the Effect of Sodium Azide on Microbic Growth and Respiration: IV. The Effect of Sodium Azide on Glucose Fermentation and Lactic Acid Production by Streptococci and Lactobacilli.

A study of t'.e effects of sodium azide on the gas metabolism of Bacillus subtilis and Pseudomonas aeruginosa under aerobic conditions has been described (Lichstenm and Soule, 1944c). It was shown that the chemical exerted an inhibitory effect on the oxygen consumption of these bacteria, and the respiratory quQtients obtained suggested that the organisms were respiring anaerobically. The fac. t...

Mutagenic interactions in combined treatments of ethylmethane sulphonate,diethyl sulohate and sodium azide on barley

Reaction of Sodium Azide with 1,1'–Dicyclohexenyl–Diepoxides

Nucleophilic ring opening of dl and meso 1,1¢- dicyclohexenyl diepoxides by sodium azide in dioxane and aqueous alcoholic medium give the corresponding azidoalcohols. The obtention of departure diepoxides from diazidoalcohols by the reaction with sodium hydride shows the anti position of OH and N3 groups.

arylaminotetrazoles : via [2+3] cycloaddition of nitriles and sodium azide via solid acid catalysis

The [3+2] cycloaddition between various nitriles and sodium azide proceeds smoothly in the presence of zeolite and sulfated Zircona as effective catalyst and in the water and DMF/MeOH, to give the corresponding arylaminotetrazoles in good to high yields. The reaction most probably precedes through the in situ formation of a catalyst azide species, followed by a successive [3+2] cycloaddition wi...
