Characterization of an Anti-gout Xanthine Oxidase Inhibitor from Pleurotus ostreatus
We selected Pleurotus ostreatus from among several edible mushrooms because it has high anti-gout xanthine oxidase (XOD) inhibitory activity. The maximal amount of XOD inhibitor was extracted when the Pleurotus ostreatus fruiting body was treated with distilled water at 40℃ for 48 hr. The XOD inhibitor thus obtained was purified by Sephadex G-50 gel permeation chromatography, ultrafiltration, C...
متن کاملSpectral characterization and chemical modification of FMN-containing ascorbyl free-radical reductase from Pleurotus ostreatus.
Ascorbyl free-radical reductase was purified 1143-fold with an overall yield of 9.9% from the cytosolic fraction of Pleurotus ostreatus. The native enzyme had a molecular mass of 127 kDa and SDS/PAGE revealed that the enzyme consists of two subunits, each with a molecular mass of 62 kDa. The enzyme utilized only NADH as an electron donor. The enzyme was highly specific for ascorbyl free radical...
متن کاملProduction and purification of statins from Pleurotus ostreatus (Basidiomycetes) strains.
Pleurotus ostreatus strains were cultured in liquid medium and on wheat straw. The yields of lovastatin were compared.
متن کاملDegradation of Green Polyethylene by Pleurotus ostreatus
We studied the biodegradation of green polyethylene (GP) by Pleurotus ostreatus. The GP was developed from renewable raw materials to help to reduce the emissions of greenhouse gases. However, little information regarding the biodegradation of GP discarded in the environment is available. P. ostreatus is a lignocellulolytic fungus that has been used in bioremediation processes for agroindustria...
متن کاملPurification and characterization of lipoxygenase from Pleurotus ostreatus.
Lipoxygenase was purified homogeneously from cups of Pleurotus ostreatus by Sephacryl S-400 HR gel filtration, Dyematrex Green A affinity, and DEAE-Toyopearl 650M ion-exchange chromatographies. The molecular weight of the enzyme was estimated to be 67,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and 66,000 by gel filtration; the isoelectric point was pH 5.1. The optimum pH a...
