Overview Title: An Efficient Biocatalytic Process to Manufacture Simvastatin Summary: Simvastatin, a leading drug

Overview Title: An Efficient Biocatalytic Process to Manufacture Simvastatin Summary: Simvastatin, a leading drug for treating high cholesterol, is manufactured from a natural product. The traditional multistep synthesis wasteful and used large amounts of hazardous reagents. Professor Tang conceived a synthesis using an engineered enzyme and a practical low-cost feedstock. Codexis optimized both the enzyme and the chemical process. The resulting process greatly reduces hazard and waste, is cost-effective and meets the needs of customers. Some manufacturers in Europe and India use this process to make simvastatin.

Overview Title: Enzymes Reduce the Energy and Wood Fiber Required to Manufacture High-Quality Paper

Overview Title: Enzymes Reduce the Energy and Wood Fiber Required to Manufacture High-Quality Paper and Paperboard Summary: Traditionally, making strong paper required costly wood pulp, energy-intensive treatment, or chemical additives. But that may change. Buckman’s Maximyze® enzymes modify the cellulose in wood to increase the number of "fibrils" that bind the wood fibers to each other, thus making paper with improved strength and quality -without additional chemicals or energy. Buckman's process also allows papermaking with less wood fiber and higher percentages of recycled paper, enabling a single plant to save $1 million per year.

Motivation Innovations in Science and Engineering • • • Cellulose fibers are the basic

Motivation Innovations in Science and Engineering • • • Cellulose fibers are the basic structural material of paper Properties of a sheet of paper like strength and weight depend on bonding between cellulose fibers Existing Technology: o Papermakers can improve paper strength by: § § § o Increasing mechanical treatment (requires significant energy expenditure) Using various chemical additives (many derived from non-renewable resources) In nature, cellulases are enzymes that catalyze the hydrolysis of cellulose to degrade and recycle this organic compound § § § • Adding different wood pulps (costly) Endoclucanases disrupt the crystalline structure of cellulose and expose individual chains Exocellulases separate pieces of two to four sugar monomers from the exposed chains Cellobiases hydrolyze those fragments into glucose o Can enzymes like cellulases be used to improve papermaking? Can we do better?

Technology Development • • • Approach: Select enzymes within the cellulase group to modify

Technology Development • • • Approach: Select enzymes within the cellulase group to modify cellulose fibers in order to improve paper quality and support greener manufacturing practices. Maximyze technology consists of certain new enzymes and combinations of enzymes, not previously available on a commercial basis, which allow for the production of paper and paperboard with improved strength and quality. Using selected cellulase enzymes to modify the surface of the cellulose fibers improves the inter-fiber bonding, increasing the strenght of paper.

Technology Development • Approach: Select enzymes within the cellulase group to modify cellulose fibers, improving paper quality and the manufacturing process. Bonding of Cellulose Fibers (500 x) Refined, no enzyme treatment Treated with Maximyze, then refined The untreated fibers display minimal amounts of fibrillation that contribute to interfiber bonding. There are limited examples of fibrils interconnecting adjacent fibers. With Maximyze, a stronger sheet can be made.
