With a total of 3 patents, his work has implications for both industrial applications and scientific research.
Latest Patents
Hirata's latest patents include a groundbreaking process for producing optically active .alpha.-hydroxycarboxylic acid. This biological process allows for the production of an optically active .alpha.-hydroxycarboxylic acid with a phenyl group directly from a racemic .alpha.-hydroxynitrile or a mixture of an aldehyde and prussic acid. The method involves reacting specific microorganisms, such as those from the genus Rhodococcus, Alcaligenes, Brevibacterium, or Pseudomonas, in a neutral to basic aqueous medium. The result is a high-yield production of the desired compound with excellent optical purity.
Another significant patent focuses on a method for preserving the activity of nitrile hydratase or nitrilase enzymes. This innovative approach allows for the prolonged preservation of microbial cells containing these enzymes in a neutral or weakly basic aqueous solution of inorganic salts. The method ensures that enzyme activity is maintained for extended periods, even at room temperature, thus reducing labor and cooling costs associated with traditional preservation methods.
