The Bactericidal Action of Synthetic Detergents
1. The bactericidal action of a number of anionic and cationic synthetic detergents on four Gram-positive and three Gram-negative bacteria has been investigated. 2. Cationic detergents, as a group, were found to exhibit marked bactericidal effects on Gram-positive microorganisms and somewhat less pronounced action on Gram-negative organisms. 3. The anionic detergents were germicidal only agains...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولThe Action of Cationic Detergents on Bacteria and Bacterial Enzymes.
The bactericidal action of the quaternary ammonium detergents has not yet been satisfactorily explained. Recent reviewers (Putnam, 1948; Rahn and Van Eseltine, 1947; cf. Glassman, 1948) have not agreed that the amounts of these detergents lethal to bacteria are insufficient to cause any general denaturation of the bacterial proteins (Valko, 1946). Action by enzyme inactivation, either primary o...
متن کاملThe "Reversal," Neutralization, and Selectivity of Germicidal Cationic Detergents.
The reversal of the inhibitory action of antiseptics by substances showing a specific affinity for the inhibiting agent has been reported for many compounds, the most striking effect probably being the reversal of the action of mercurials by H2S, glutathione, sodium thioglycolate, etc. Valko and DuBois (1944) have reported that the germicidal action of cationic detergents against both gram-posi...
متن کاملThe isolation of Escherichia coliphage by means of cationic detergents.
The action of synthetic detergents upon several strains of bacteriophage has been mentioned in a previous communication (Klein et al., 1945). With the exception of gamma coli phage, the bacteriophages tested were highly susceptible to the germicidal activity of the various test compounds. The gamma phage, on the other hand, proved to be resistant to the highest concentrations of the detergents ...
