Latest Patents
One of Yu's key patents is titled "Method for purifying xylanase." This patent describes a process for separating xylanases from mixtures with other hemicellulases, particularly cellulase. The method involves culturing hemicellulolytic microorganisms, specifically the fungus Trichoderma harzianum E58 and Trichoderma reesei. The separation is achieved through ultrafiltration using a membrane with a low molecular weight cut-off point ranging from about 1,000 to 20,000 daltons. This process results in a cellulase-rich retentate and a xylanase-rich ultrafiltrate. The xylanase-rich filtrate is then concentrated and purified using adsorption and elution techniques from an insoluble matrix, such as a cationic exchange resin. The xylanase obtained is particularly effective for the hydrolysis of hemicellulose, especially in the presence of cellulose.
Career Highlights
Throughout his career, Yu has focused on advancing enzyme technology and its applications in various industries. His innovative methods have contributed to more efficient processes in biotechnology and have opened new avenues for research and development in enzyme purification.
