The oxidation of tricarboxylic acid cycle compounds by Penicillium chrysogenum.
The presence of a tricarboxylic acid cycle in Penicillium chry8ogenum, as yet, has not been demonstrated conclusively. Ajl (1951) stated that of the mechanisms proposed for oxidation of the 2 carbon fragment in mold metabolism, the evidence for a tricarboxylic acid cycle is the least convincing. This paper presents a study of some of the enzymes of the tricarboxylic acid cycle in cell-free prep...
متن کاملThe oxidation of glucose by Penicillium chrysogenum.
Studies on the mechanism of glucose metabolism by penicillia are few. The fact that Snell (1949) and Kita (1951) found none of the phosphorylated esters of the Embden-Meyerhof scheme in PeniciUium chrysogenum, strain Q176, and that penicillia contain glucose oxidase (Birkinshaw and Raistrick, 1943) would indicate a priori that glucose is metabolized oxidatively by the mold. The following data i...
متن کاملIntracellular Biosynthesis of Gold Nanoparticles by the Fungus Penicillium Chrysogenum
In this study, the biosynthesis of gold nanoparticles by Penicillium chrysogenum, isolated from Ahar copper mine, was investigated. The gold nanoparticles were synthesized by reducing the aqueous gold ions using the culture supernatant of the filamentous fungi. The UV–vis spectrum displayed a characteristic peak at 532 nm that is very specific for gold nanoparticles. The XRD spectrum confirmed ...
متن کاملAcetic acid oxidation by Escherichia coli; quantitative significance of the tricarboxylic acid cycle.
Krebs (1937) reported that acetate and a number of other substrates were oxidized under anaerobic conditions by nonproliferating suspensions of Eschrichia coli when fumarate was added as an oxidant. These observations resulted from a study of the role of fumarate in respiration, and no consideration was given to the mechanism of acetate oxidation. The over-all reaction for the oxidation of acet...
متن کاملAcylation of 6-Aminopenicillanic Acid by Penicillium chrysogenum.
num deacylated phenoxymethylpenicillin about six times faster than benzylpenicillin to 6-aminopenicillanic acid (6-APA) (R. C. Erickson and R. E. Bennett, Bacteriol. Proc., p. 65, 1961; Erickson and Bennett, Appl. Microbiol. 13:738, 1965. This was observed with a penicillin-nonproducing strain, Wis 49408 (obtained from the University of Wisconsin), and with a penicillinproducing strain, P-5009 ...
