The Antibacterial Action of Surface Active Cations.
The antibacterial action of surface-active cations was reported by Hartmann and Kiigi (1928) on the basis of observations made by Doerr. Domagk (1935) gave a detailed description of the bacteriological properties of a very potent member of this group. Notwithstanding the considerable attention which these discoveries aroused, as shown by the number of investigations reported in the literature, ...
متن کاملBiosynthesis of Cyclopropane Compounds
Several natural and synthetic phospholipids can serve as substrates for the cyclopropane synthetase enzyme of Closfridium bufyricum. The conditions for optimum substrate effectiveness vary with the substrate; e.g. an anionic surfaceactive agent is necessary with phosphatidylethanolamine, while divalent cations stimulate the rate of reaction with anionic phospholipids. These variable conditions ...
متن کاملDetermination of the chemical nature of active surface sites present on bulk mixed metal oxide catalysts.
CH3OH temperature programmed surface reaction (TPSR) spectroscopy was employed to determine the chemical nature of active surface sites for bulk mixed metal oxide catalysts. The CH3OH-TPSR spectra peak temperature, Tp, for model supported metal oxides and bulk, pure metal oxides was found to be sensitive to the specific surface metal oxide as well as its oxidation state. The catalytic activity ...
متن کاملEffects of organic cations on the gram-negative cell wall and their bactericidal activity with ethylenediaminetetra-acetate and surface active agents.
When Gram-negative cell walls were damaged by lysozyme and ethylenediaminetetra-acetic acid (EDTA) in tris buffer, tris played an active role through its action as an organic cation. Other organic cations such as aliphatic amines and quaternary ammonium compounds were more effective than tris in modifying the cell wall and making it permeable to other solutes. The most effective organic cations...
متن کاملEffect of a quaternary ammonium germicide on electrophoretic mobility of Escherichia coli in various salt solutions.
Quaternary ammonium compounds, effective as sanitizing agents for food plant equipment under certain conditions, are not well suited as sanitizers for water of high mineral content. Mueller and Seeley (1951) have demonstrated under controlled conditions that various metallic cations can decrease the germicidal action of a quaternary in solution. Knowledge of how such interference takes place co...
