Title: The Innovative Contributions of Yunn B Yang in Enzyme Production
Introduction: Yunn B Yang, based in Taipei, Taiwan, is a notable inventor recognized for his significant contributions to the field of enzyme production. With a total of two patents, Yang has made strides in the development of processes that enhance the production of valuable aminoacylases, which hold various applications in both commercial and medical fields.
Latest Patents: Yang's latest patents include processes for making D-aminoacylase and L-aminoacylase. The patent for D-aminoacylase outlines a method that involves adding 1% N-acetyl-DL-amino acids, such as N-acetyl-DL-methionine and N-acetyl-DL-leucine, to a culturing medium that is incubated with a selected strain of Alcaligenes faecalis. This innovative method is designed to cultivate bacteria that promote enzyme reactions to produce D-aminoacylase, which is capable of hydrolyzing D-amino acids while being unable to act on L-amino acids. The patent for L-aminoacylase describes a cultivation process using microorganisms from the Alcaligenes species, particularly Alcaligenes denitrificans DA 181. This process allows for the separation of the produced L-aminoacylase from bacterial cells, facilitating further purification for L-amino acid production. The acylase produced through this approach boasts increased stability, enhancing its commercial and medical viability.
