DuPont Industrial Biosciences has agreed to buy Dyadic International’s industrial enzymes business for $75 million. Dyadic was founded in 1979 by Mark Emalfarb, now CEO. It started in the enzyme business by supplying cellulases and pumice stones for making stonewashed denim. It has since developed a fungal production platform to make industrial enzymes used in the biofuels, biobased chemicals, food, and animal health industries. In 2014, the company had revenues of $12.5 million and a loss from operations of $5.3 million. DuPont will also acquire Dyadic’s Netherlands research and development lab.
