Abstract

A method for degassing ink, and resulting degassed ink includes the addition of at least two enzymes to ink containing a donor substrate specific to each enzyme, wherein one of the enzymes catalyzes a chemical reaction to produce hydrogen peroxide upon exposure to a gaseous acceptor substrate, and another enzyme subsequently catalyzes a reaction to convert the hydrogen peroxide into water.
