Enzymes by source

High Temperature Enzymes
The Company’s high-temperature, high-activity bacterial enzymes from Clostridium thermocellumDictyoglomus turgidumAcidothermus cellulolyticus, and Geobacillus species can provide unique benefits in the conversion of biomass. C5-6’s approach, utilizing thermostable enzymes to convert various forms of cellulosic biomass could be incorporated within the existing dry mill process technology or be coupled to processes producing a high temperature product stream, such as steam explosion. The use of high temperature enzymes provides a lower cost alternative to conventional processes for cellulosic conversion.

 C5•6 supplies fungal enzymes from Trichoderma reesei and other fungi.  These enzymes are more aciduric and slightly less thermostable  than their bacterial counterparts, and are often used for research on biomass degration.

 

Low Temperature, Neutral pH Enzymes
C5•6 supplies bacterial enzymes from Fibrobacter succinogenes and Cellulomonas species to convert biomass to fermentable sugars under mild conditions. The use of low temperature, neutral pH enzymes can reduce the time and cost of cellulosic fuel production by creating a true SSF (simultaneous saccharification fermentation) process.

Low Temperature, Alkaline pH Enzymes
C5•6 supplies bacterial enzymes from Bacillus cellulosilyticus for converting biomass to fermentable sugars under conditions compatible with alkaline pretreated biomass.  The use of low temperature alkaline enzymes can reduce the time and cost of cellulosic fuel production by eliminating the cost of pH adjustment and alkali removal before saccharification.
