FREMGANGSMADE TIL FREMSTILLING AF L-LYSIN

摘要

A process for the preparation of lysine destined for alimentary use consists in starting from lactoserum or lactose containing juice, subjecting it to an enzymatic, acid or catalytic hydrolysis in the presence of a lysine- producing microorganism and drying the mixture thus obtained. The hydrolysis is preferably effected by an enzymatic route, e.g. with beta -galactosidase, or by a catalytic route with an ion exchange resin. The lysine producing microorganism may be Corynebacterium glutamicum, Brevibacterium Arthrobacter sp. or Corynebacterium lilium.
