Integrated production lowers enzyme cost of ethanol

MONTREAL, Canada (ICIS)--The integration of enzyme production can significantly lower the enzyme cost per gallon of ethanol, an industry executive said on Monday.

An advantage of integrated enzyme production is low substrate cost because enzymes are produced on lignocellulosic substrate, said Andre Koltermann, head of the biotech and renewables centre for Switzerland-headquartered chemicals firm Clariant.

There is no additional utilities as enzymes production is process and plant integrated, and there is no formulation and logistics because enzymes are produced directly where needed, he said at the World Congress on Industrial Biotechnology conference.

Additionally, integrated enzyme production is independent from enzyme suppliers, so there are no additional margins due to pricing strategy, Koltermann said.

The process will require feedstock and process-specific enzymes because there is no “one-size-fits-all” solution, he added

The World Congress on Industrial Biotechnology conference runs through Wednesday.
