Popis: | Cells of suspension culture Citrullus vulgaris cv. “Samara” were permeabilized by Tween 80 and immobilized by glutaraldehyde. The highest melibiase activity was at pH 5.4 and 60°C. The hydrolysis of substrate was linear for 3.5 h, reaching 65–70% conversion of the substrate. The cells, characterized by high enzyme activity and stability in long-term storage, showed convenient physico-mechanical properties (physical protection from shear forces and easy separation of product from biocatalysts). |
