Industrial fermentation processes for biobased chemical and advanced fuels are promising, but they often plagued with low concentration and high product separation costs. DAB has developed a robust, patented, bioreactor technology that overcomes some of the major pitfalls of industrial fermentation through the combination of fermentation and separation into a single vessel, enabling in-situ product recovery. DAB helps intensifying large scale biobased chemical and fuel production industry to produce more for less.
