The effect of nutrients on formation of penicillin by washed mycelium of Penicillium chrysogenum.
Many different substances are known to affect the yields of penicillin from growing cultures of Penicillium chrysogenum. Under the usual conditions, it is difficult to distinguish between the effect of a substance on growth of the mould (and hence the indirect effect on production of penicillin) and its direct effect on antibiotic synthesis. The use of washed mycelium (Halliday & Arnstein, 1956...
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 کاملProduction of penicillin with waste mycelium Penicillium chrysogenum as the sole source of nitrogen.
In a preliminary communication (Ghosh, 1959) it was reported that fresh and wet mycelium of Penicillium chrysogenum, as obtained from a rotary filter in a penicillin plant, could be well utilized as the sole source of nitrogen for penicillin production by the mold either in shaken flask or in aerated and agitated large fermentors. The waste mycelium did not need any pretreatment whatsoever and ...
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...
