Accelerating Cellulosic Ethanol Commercialization

Our Consolidated Bioprocessing (CBP) platform enables an integrated cellulosic ethanol value chain that maximizes process efficiency and production profitability.

Our CBP platform leverages the natural advantages of the Q Microbe®, which produces virtually all the enzymes required to digest biomass into fermentable sugars and contains all pathways required for biomass conversion into ethanol. The result is a single-step conversion process that dramatically reduces the cost and complexity of producing cellulosic ethanol at commercial scale from a broad variety of non-food feedstocks.

The CBP platform based on the Q Microbe delivers an ethanol production process that is:

  • Highly efficient, the natural metabolism of the Q Microbe enables direct fermentation of oligomeric sugars, requiring less severe, lower cost pre-treatment processes.
  • Highly productive, the Q Microbe ferments all C5 and C6 sugars, resulting in overall higher conversion of biomass to ethanol compared to yeast-based processes, while enabling fewer production steps and minimizing the addition of exogenous enzymes.
  • Highly flexible, the Q Microbe is feedstock agnostic, producing high yields of cellulosic ethanol from a broad range of biomass materials, including corn stover and cobs, bagasse and energy crops. This broad flexibility allows producers to utilize low-cost, locally sourced feedstocks.
  • Highly scalable, our process is optimized for efficient, industrial-scale production in markets around the world.

By dramatically reducing bioprocessing steps and resource requirements, our CBP platform represents the major step-function change needed to accelerate global cellulosic ethanol production at a commercial scale. Read more at
