Penicillin Chapter 13 1957

Mechanism of action of penicillin.

Studies on the sensitivity and effect of penicillin on oral lactobacilli.

Increased staphylococcal penicillinase activity accompanying penicillin treatment of experimentally infected mice.

In a previous communication, experiments were reported which indicate that the basal (constitutive) level of penicillinase in pathogenic penicillin resistant strains of Staphylococcus aureus can be inducibly elevated 10to 15-fold by in vitro exposure to penicillin under appropriate conditions (Geronimus and Cohen, 1957). If similar elevations in penicillinase activity are induced by penicillin ...

A study of lipides of Penicillium chrysogenum.

Relatively few studies have been made on the lipide metabolism of Penicillium chrysogenum, although large quantities of these compounds are used as antifoam agents in the production of penicillin. Goldschmidt and Koffler (1) demonstrated that unsaturated long chain fatty acids present in the antifoam were responsible for stimulation of penicillin yields, since many physiologically inert compoun...

Penicillin and tetracycline as contamination control agents in alcoholic fermentation of sugar cane molasses.

Several papers have been published to show the use of antibiotics as inhibitors of foreign microorganiisms in industrial fermentations (Strandskov and Bockelmann, 1953; Day et al., 1954; Borzani and Aquarone, 1957; Aquarone, 1958; Falcone, 1958; Torloni et al., 1958; Falcone, 1959; Aquarone, 1959) to assure high yields and/or good quality products. The favorable influence of penicillin as a con...
