Abstract:
A method of conducting an enzymatic process in which the enzymes are recovered and reused in at least a second iteration of the process, wherein each iteration of the process comprises the steps of: (a) providing a heterogeneous substrate solution, in which the substrate is fully soluble, partially soluble or insoluble; (b) adding an enzyme or mixture of enzymes to the heterogeneous substrate solution; and (c) allowing an enzymatic reaction of the substrate to proceed; wherein, after completion of step (c) for each iteration, the enzyme is recovered from the mixture resulting from step (c) according to the following steps: (d) conducting a non-packed-bed adsorption process comprising contacting the reaction mixture with an adsorbent that adsorbs the enzyme in order to separate the enzyme from the reaction mixture resulting from step (c); (e) optionally washing unbound material from the adsorbent; and (f) desorbing the enzyme from the adsorbent; and further wherein the desorbed enzyme obtained in step (f) is used in step (b) of at least one subsequent iteration of the process.
Abstract:
The present invention provides industrial scale expanded bed adsorption process for fractionation and isolation of bio-molecules from fluids, preferably proteins from milk and whey, in a cost-effective manner. This is accomplished by operating the expanded bed column at high temperatures of at last 40°C, combined with applying flow rates greater than 1.500 cm/hour.
Abstract:
The invention provides a process for the separation of soy protein. The process begins with an aqueous extract or solution of soy protein, which is passed through at least one expanded bed absorption (EBA) process. The EBA process comprises contacting the aqueous extract or solution of soy protein with at least one adsorbent resin, said adsorbent resin comprising at least one ligand (L1 or L2), having particular chemical structures. Proteins of interest (e.g. trypsin inhibitor (TI) protein or beta-conglycinin) are isolated by eluting them from said adsorbent resin. The invention also provides various novel protein compositions obtainable via the method of the invention.
