Polygalacturonase (PG) production by Penicillium chrysogenum during solid-state fermentation was accompanied by decomposition of orange peels. A leaching procedure was developed through the selection of solvent, time and intensity of stirring. A maximum PG activity was observed after 48 h peel inoculation. Further cultivation decreased the enzyme activity(More)
UNLABELLED The Escherichia coli K-12 strain BL21/pETSD10 was used to produce recombinant endocellular 1,3-β-glucanase. This enzyme is responsible for the hydrolysis of the glycosidic bond in specific polysaccharides with tracts of unsubstituted β-1,3-linked glucosyl residues. Conditions for the overproduction were experimentally examined, and the optimal(More)
