The 2-ZYME technology applies the selectivity of bio-catalytic conversions to transform underused biomass fractions of major bioresource sectors into sought-after biochemicals. By leveraging natural structures in underused biomass, the 2-ZYME technology increases bioresource efficiency while diversifying the product portfolio of existing biorefineries.The technology combines two enzymes in one pot to produce glucaric acid from glucuronoxylans an underused fraction of wood and agricultural biorefineries making cellulose pulps and bioethanol, respectively. Glucaric acid is a platform chemical that serves as a key building block for biopolymer synthesis, and is also used as such in phosphate-free detergents along with de-icing agents. The global glucaric acid market size was estimated at USD 550.4 million in 2016 with a projected cumulative average growth rate (CAGR) of 7% during the 2018-2023 period. Advantages of the 2-ZYME technology over the conventional approach to producing glucaric acid include high product purity and yield, and low feedstock costs.A recently completed NSERC I2I Market Assessment of the 2-ZYME technology confirmed the market readiness for this new enzyme system. The current NSERC I2I Phase I project will focus on three specific tasks needed to secure private sector investment: 1) detailed compositional analysis of underused biomass streams produced by existing biorefineries to inform deployment efforts, 2) application of the 2-ZYME technology to the prioritized glucuronoxylan sources, and 3) prove out lab scale-up of the 2-ZYME technology including product recovery.To achieve the project goals, the proposed action assembles committed industrial partners, including feedstock providers (Fortress Advanced Bioproducts, IGPC Ethanol), biotechnology developers (Novozymes), and market experts (Pansophy Consulting), to create a focused academic-industry partnership that is motivated and fully equipped to realize the economic potential and environmental benefits of the 2-ZYME technology.

2-ZYME技术应用生物催化转化的选择性，将主要生物资源部门未充分利用的生物质部分转化为受欢迎的生物化学品。通过利用未充分利用的生物质的自然结构，双酶技术提高了生物资源效率，同时使现有生物精炼剂的产品组合多样化。该技术将两种酶结合在一个锅中，从葡萄糖醛酸木聚糖(未充分利用的木材部分)和农业生物精炼厂分别生产纤维素纸浆和生物乙醇。葡萄糖酸是一种平台化学品，是合成生物聚合物的关键构件，也可用作无磷洗涤剂和除冰剂。2016年全球葡萄糖酸市场规模估计为5.504亿美元，2018-2023年期间的累计平均增长率(CAGR)预计为7%。与生产葡萄糖酸的传统方法相比，双酶技术的优势包括产品纯度和产量高，原料成本低。最近完成的NSERC I2I对双酶技术的市场评估证实了这种新的酶系统的市场准备情况。目前的NSERC I2I第一阶段项目将侧重于确保私营部门投资所需的三项具体任务：1)对现有生物精炼厂生产的未充分利用的生物质流进行详细的成分分析，为部署工作提供信息；2)将2-ZYME技术应用于优先考虑的葡醛酸木聚糖来源；3)证明2-WYME技术的实验室规模，包括产品回收。为了实现项目目标，拟议的行动汇集了承诺的工业合作伙伴，包括原料提供商(堡垒高级生物制品公司、IGPC乙醇公司)、生物技术开发商(Novozymes)和市场专家(Pansopy Consulting)，创建一个有针对性的学术和产业合作伙伴关系，有动力并具备充分的装备，以实现2-ZYME技术的经济潜力和环境效益。
