Many companies have begun process development and scale-up of their cellulosic biomass conversion technologies.  It was Genencor’s desire to quickly launch a product to support the needs of these process developers.  This paper will discuss many of the steps to launching this first commercial product specifically for this market, including the design of the enzyme system, performance testing and validation, confirming reproducible production quality and delivering on needed production cost reductions.  Performance comparisons will be shown between Accellerase^TM 1000 and Spezyme^R CP, a previous benchmark cellulase product from Genencor.
