Abstract
A liquid stream containing the reactants is passed through a bed of enzyme catalyst, made up of enzymes bonded to small, dense particles of carrier or support materials, in a manner which causes the bed to expand or fluidize and a chemical reaction is thereby carried out in a process that is simultaneously free from limitations due to plugging and excessive pressure drop and which also has the advantage of the high mass transfer rates that can be realized between the liquid and small particles. Reactions are carried out in this manner using enzymes bound to porous and non-porous inorganic supporting particles. This process has been employed for treating cheese whey with the enzyme lactase in a fluidized bed of inert particles to which the lactase is bound.
