Youtell Biochemical focuses exclusively on the research, development, manufacturing, and marketing of enzyme products across the world. Youtell's core technologies are developed in the company's state of the art biotechnology research center in Bothell, WA USA. Two additional application research centers located in Shanghai and Hunan, China support product development. Youtell is also proud of its two fermentation and down-stream processing factories which produce the company's entire portfolio of products. By using Youtell's own patented-technologies, we make over 80,000 metric tons of enzyme products annually with high activity and purity. Our products are widely used in cotton and ramie fabric processing, animal feed, brewing, food, paper processing, plant extraction, pharmaceutical and bio-energy--remarkably improving process efficiency and reducing waste release and environmental pollution across a myriad of industries.
