The correct option is (c) Recovery of the biocatalyst
The best I can explain: For immobilized enzymes, the following things are governed by the volumetric surface area (A/V) is an important parameter:
• The overall flux of the substrate to the biocatalytic surface,
• The effectiveness of the enzyme and
• productivity.
Recovery of the biocatalyst is an advantage of impregnated wet beads along with some others which are as follows:
• Protection of the contained enzyme at higher rates of stirring.
• Allows to be used with low molecular weight hydrophilic coenzymes with the assistance of a coenzyme regenerating process.
• Allowing efficient and continuous use of biphasic PBRs as long as the moving organic phase is saturated with water.
