ABSTRACT:
Enzymated products are made in a continuous process by
(a) continuously passing a substrate and an enzyme containing fermentation broth into a reaction zone,
(b) continuously passing the converted product from in said reaction zone to a filtration zone for separation of the enzyme from said product,
(c) continuously recycling enzyme remaining as the retentate in the filtration zone back into said reaction zone, and
(d) continuously collecting the converted product received as the filtrate from said filtration zone,
The said reaction zone and filtration zone forming a closed circulation circuit.
