MetZyme® PURECO™ is a next-generation enzyme family for valorizing all biorefinery material streams: conversion of sugars and lignin.
Enzymes in this family are individually customized for each substrate and process. This attention to detail significantly improves the economics of biochemicals production from the lignocellulosic feedstock. PURECO™ enzymatic solutions are specifically tailored for biochemical conversion to value-added renewable chemicals.
PURECO™ family includes, but is not limited to following unique solutions:
- LIGNIN FRAGMENTATION AND FRACTIONATION
- LIGNIN POLYMERIZATION
- GLUCOSE ISOMERIZATION EVEN IN UNPURIFIED HYDROLYSATES
- FULL GLUCOSE BIOCONVERSION TO OTHER PLATFORM SUGARS – AND FURTHER CONVERSIONS TO PLATFORM CHEMICALS
PURECO™ products consist of a variety of novel enzymes needed for challenging conversions and conditions in complex value-chains. These enzymes enable Wood-to-Chemicals processes, and with that, a source of more sustainable and renewable chemical building-blocks for better products and materials.
Opportunities include, but are not limited, to bioplastics, sorbitol, xylitol, furfural, 5-HMF, FDCA, and organic acids. New technologies supporting Biofuels – such as jet fuel, biogas, or even lignin-based marine diesel – are made available to the industry.
One of the most exciting newly developed technologies is based on lignin oxidizing enzymes with stability and activity optimum at pH 11. This technology enables lignin fractionation in water-soluble conditions without solvents or heavy metal catalysts. Most abundant source of aromatics is finally available for resins, adhesives, composites, elastomers, foams, cosmetics… you name it!
Furthermore, utilizing the power of ENZINE® platform, all MetZyme® PURECO™ enzymes can be optimized for a wide range of pH and temperature specifications as well as other harsh conditions, such as high concentration of solvents, allowing for a drop-in solution to most biorefinery processes.
MetGen’s team of experts are always available to ensure an optimal selection of enzyme for the process – and offers help to continuously improve the new enhanced process.
PURECO™ unleashes the power of MetGen’s technology platform by extending the enzymatic toolbox to cover also the chemical conversions after the pre-treatment and hydrolysis.
EXAMPLE CASE: H2020-PROJECT ReTAPP – Enabling the Value-Chain form Wood to Plastic Packaging
Wood-based fructose has not been utilized for bioplastic production because the enzymes required for the conversion cannot tolerate the inhibitors in the hydrolysate without extensive purification. MetGen designed a superior enzyme with wide tolerance towards inhibitors such as lignin and other sugars. The power of designer enzymes is clearly demonstrated in the figure below.
As in real-life, the valorization of wood in the ReTAPP project is a complex process, which can be addressed with enzymatic solutions on many stages.
- MetZyme® LIGNO™ is used for better separation of hemicellulases in pretreatment stage. Resulting soluble fraction has most of the xylose for further conversion to value-added chemicals.
- MetZyme® SUNO™ provides higher hydrolysis yields, increased dry-matter content and more affordable production of glucose.
- MetZyme® PURECO™ is used to convert glucose to fructose.
Fructose is chemically converted first to 5-HMF, then to FDCA, and ultimately to PEF resin. Xylose is converted to Xylulose, but it can also be further converted to xylitol or furfural.
Let MetZyme® PURECO™ take your process beyond sugars!
