Materials or products produced

Direvo uses its proprietary technology to provide a biological solution to the grain-to-ethanol industry leading to value-enhanced DDGS (dried distillers grains and solubles). This offers a clear win for both the ethanol plant and the animal producer.

  • • Superior DDGS quality: Enables high inclusion rates in poultry feed
  • • Improved economics: Superior DDGS has a higher market value than standard DDGS
  • • No capital expense: Easy implementation in existing processes
  • • Process stability: Production efficiency can be improved, for example by dewatering, oil separation or evaporation

Feedstock: DDGS

Product Brand Name: BluZy-D

Product Description: BluZy-D is a proprietary enzyme product applied to the fermentation products of the standard dry mill ethanol process. A typical by-product of this process is DDGS, which has become a widely accepted ingredient in livestock and poultry feed. However, the potential value of DDGS in animal feed has not been fully realized due to a variety of reasons. BluZy-D increases the nutritional quality of DDGS and establishes greater access for DDGS to the poultry and hog feed markets.

Product Applications: 

The BluZy-D enzyme blend is directly added after fermentation without disturbing the process itself or any needed for additional capital expenditures. Through the atcion of our proprietary enzymes components are removed of modified. Thereby, we  improve the nutritional quality of  DDGS within the process with no hassle to the producer.

Unique Features (i.e.,what separates this product from the competition, whether bio-based or incumbent fossil-based products – e.g. cost, performance features).

BluZy-D is the only product being applied directly to the grain-to-ethanol process resulting in superior DDGS nutritional quality.

Materials or products produced

Direvo uses its proprietary technology and rigorous screening methods to create optimal bacteria, which in turn produce the lowest-cost biofuels and chemicals from a broad variety of non-food biomass inputs.

Currently, we are focusing on the production of ethanol and lactate

  • • Low capital expense: simple consolidated process in one vessel
  • • Low operating expense: Direvo’s bacteria contain all the enzymes needed for the conversion of lignocellulose to the desired end products
  • • Feedstock-agnostic: Direvo’s bacteria efficiently convert agricultural residues, energy crops and hardwood
  • • Robust, reliable process: fermentation occurs at above 70 degrees celsius

Status: (Open, Under Construction, Planned)



Grasses, e.g. straw, stover, miscanthus, switchgrass, bagasse

Product information:

Product Brand Name: BluCon-P

Product Description: 

BluCon-P is a portfolio of robust extremophile bacteria capable of fermentation at above 70 degrees C. The BluCon-P bacteria accept diverse sources of pretreated biomass including hardwood, grasses, bagasse and corn cobs. Ethanol and lactate are the primary products. Direvo is improving the competitiveness of its process in three key areas that will allow it to improve BluCon-P to the point where the cost of ethanol is comparable to that of fossil fuel. These areas are metabolic engineering, by which genes in the bacteria are knocked out in order to focus production on the desired end products; process optimization to improve yield; and strain optimization to make the bacteria optimally robust in their industrial environment.

Product Applications: 

Currently, we are focusing on the conversion of grasses to either ethaonol or lactate. The BluCon-P portfolio will soon also be capable of converting biomass to hydrogen and organic acids.

Unique Features

The Direvo BluCon-P consolidated bioprocessing approach reduces all relevant process steps for production of fuels and chemicals from pretreated biomass into a single fermentation tank. Enzyme production, cellulose and hemicellulose breakdown as well as conversion of both C6- and C5- sugars, all within one unit operation, make BluCon-P a highly promising approach to overcoming the pitfalls of second generation biofuel commercialization. The high process temperature eliminates contamination risk and enables in-situ capture of volatile products.
