Thermostable conidial and mycelial alkaline phosphatases from the thermophilic fungus Scytalidium thermophilum
(Nature America Inc, 2001-10-01)
An extracellular (conidial) and an intracellular (mycelial) alkaline phosphatase from the thermophilic fungus Scytalidium thermophilum were purified by DEAE-cellulose and Concanavalin A-Sepharose chromatography. These ...
