STTR Phase I: Bioprocess-derived Glucaric Acid as a Renewable Feedstock for Diverse Polymers

Project: Research project

Project Details

Description

The broader impact/commercial potential of this Small Business Technology Transfer Research Phase I project is the development of polymer applications for glucaric acid such as polyesters and polyamides. For example, the polyester segment has a potential for 9 billion pounds with a market value of $5 - $13 billion. Success on this project will catalyze the use of bioprocess-derived glucaric acid for this and other applications for which this versatile six carbon di-acid has utility. While some smaller shorter carbon chain length molecules (three to five carbons, C3-C5) based renewable materials are available, bioprocess-derived glucaric acid could represent the first major, biologically-produced C6 used for polymer synthesis if it can be successfully brought to market. Based on precedents for large-scale fermentation processes, successful translation of the glucaric acid bioprocess and polymer synthesis technology into the commercial space would also result in job creation, as bio-based plants have typically been initiated in the US. Critically this work will also further validate the commercial viability of producing commodity-scale, high value-added chemicals produced by microbes developed with synthetic biology techniques. With the United States at the forefront of synthetic biology, proven commercially successful products will lead to greater private investment in this growth sector.The objectives of this Phase I research project are: 1) demonstrate the synthesis of novel, high molecular weight polymers (>10 kDa) from glucaric acid and suitable co-monomers with useful thermal and mechanical properties, and 2) develop and evaluate genetically altered E. coli strains for improved glucaric acid production. As a novel di-acid monomer, glucaric acid provides the opportunity to explore uncharted territory in the polymer space. These new materials can serve as functional replacements allowing suppliers to leverage an alternative to petroleum feedstock-based polymers. Reaction schemes that carefully control monomer stoichiometry and drive high conversion will be employed to achieve polyesters and polyamides with molecular weights greater than 10 kDa.
