Redwood City, Calif.-based Codexis, a developer of enzyme-based manufacturing processes, said it acquired BioCatalytics, a Pasadena, Calif., producer of enzymes that speed chemical reactions. Terms of the deal weren’t disclosed; the release is here.

Both companies are focused on “biocatalysis,” a technique for using bioengineered and natural enzymes to accelerate chemical reactions, often improving their cleanliness and efficiency. Industry estimates suggest the enzyme market will expand to $2.2 billion in annual sales by 2010, up from $1.6 billion in 2005.
