Detergent-like stressor and nutrient in metabolism of Penicillium chrysogenum
The influence of detergents on the metabolism of Penicillium chrysogenum from two aspects, as a stress factor and potential nutrient, was studied. The fungus was isolated from the river bed Lepenica, Kragujevac, at a place where sewage domestic wastewater discharged into the river. The fungus was grown in a liquid nutrient medium according to Czapek with and without addition of commercial deter...
متن کاملOrganic acid metabolism of Penicillium chrysogenum. I. Lactate and acetate.
The media most useful for penicillin production contain corn-steep liquor (CSL), which has a high organic acid content. Such media usually contain about 5 mg./ml. lactic acid and rather less than 0-5 mg./ml. acetic acid. It has been found beneficial to include organic acids, especially the two mentioned, in synthetic media for penicillin production (Stone & Farrell, 1946; Jarvis & Johnson, 1947...
متن کاملPenicillin acyltransferase in Penicillium chrysogenum.
Isotopic exchange of (35)S between penicillins and 6-amino-penicillanic acid (6-APA) was observed in cell-free extracts of Penicillium chrysogenum. Sulfhydryl-containing compounds were required for activity. Dithiothreitol, dithioerythritol, mercaptoethanol, and glutathione served as activators. The acyltransferase was purified threefold by adsorption on calcium phosphate gel at pH 6 and elutio...
متن کاملThe lactic dehydrogenase of Penicillium chrysogenum.
A soluble, cytochrome linked flavoprotein which oxidizes lactic acid to pyruvic acid has been isolated from Penicillium chrysogenum, strain NRRL 1951 -B25. The reduction of cytochrome c by a flavin enzyme has precedence in the work of Horecker and Heppel (1949) and Mlorell (1952) who have shown that xanthine oxidase can reduce cytochrome c. Morell reported the enzyme to be inhibited strongly by...
متن کاملBallistic disruption of Penicillium chrysogenum cells.
The use of glass beads in a high-speed mixing device to rupture organisms was applied to molds. The use of a mixer in which the propellor shaft enters from the top into a metal mixing chamber made it possible to immerse the whole device in a salt water and ice mixture so that the temperature of the glass-bead slurry could be kept below 5 C without difficulty. Mycelia, glass beads, and buffer in...
