Summary
6-Aminopenicillanic acid from penicillin V is produced by Pleurotus ostreatus immobilized by entrapment in a chitosan matrix. In these carriers the cell concentration increases after network formation by irreversible shrinking of the biocatalyst. Specific activity of the biocatalyst for the hydrolysis reaction is 1,31 μmol.min-1. (g wet weight of catalyst)-1 corresponding to a relative activity of 38%. Catalytic half-life of immobilized Pl. ostreatus is 25 days compared to 2.5 days for free suspended cells.
