Enzyme products

A process for preparing a recombinant enzyme formulation comprising:

• (i) providing a composition I comprising a recombinant enzyme, nucleic acids, and optionally cell debris;
• (ii) adding to the composition I a nuclease wherein the nuclease breaks down the nucleic acids to result in a composition II comprising the recombinant enzyme, broken down nucleic acids, and optionally the cell debris;
• (iii) subsequently, adding to the composition II a precipitation agent for the broken down nucleic acids wherein the broken down nucleic acids are complexed resulting in a composition III comprising the recombinant enzyme, complexed broken down nucleic acids, and optionally the cell debris;
• (iv) optionally, purifying the composition III by solid/liquid separation resulting in a separated solid phase comprising the complexed broken down nucleic acids and optionally the cell debris and a liquid composition IV comprising the recombinant enzyme;
• and
• (v) subsequently, purifying the composition III or the composition IV by microfiltration resulting in a composition V, the recombinant enzyme formulation, comprising the recombinant enzyme.
