  • Multiply transformed koji mold and a method of manufacturing a flavor enhancer using the same
    Patent number: 6706492
    Abstract: The present invention provides a koji mold having increased protease activity and peptidase activity relative to a parent strain, a method of breeding the koji mold, and a method of manufacturing a flavor enhancer using the koji mold. More specifically, the present invention provides (1) a koji mold having increased protease activity and peptidase activity relative to a parent strain obtained by transformation using a protease gene and a peptidase gene, (2) a method of breeding the above koji mold which comprises transforming a parent strain of koji mold using a protease gene and a peptidase gene, and then selecting a transformant having higher protease activity and peptidase activity relative to a parent strain, and (3) a method of manufacturing a flavor enhancer which comprises allowing a culture product of the above koji mold to act on a protein.

  • Species cryptococcus nodaensis, a process for producing salt-resistant thermostable glutaminase by use of the same, and a process for producing glutamic acid-rich protein hydrolysates
    Patent number: 6063409
    Abstract: A microorganism belonging to the genus Cryptococcus having the ability to produce glutaminase excellent in salt resistance and thermostability. Further, this microorganism can be used to produce the salt-resistant thermostable glutaminase, and by use of this glutaminase, glutamic acid-rich and good tasting protein hydrolysates (e.g. flavoring foods such as soy sauce, miso etc.) are produced efficiently in a simple operation. Specifically, said microorganism is the new species Cryptococcus nodaensis having assimilability of +, -, -and - toward lactose, N-acetyl-D-glucosamine, D-glucosamine and arbtin as carbon sources, respectively.

  • Liquid treating method and liquid treating apparatus
    Patent number: 5585044
    Abstract: The liquid treating method according to the present invention introduces a bubble into liquid phase and applies vibration waves, such as ultrasonic waves, from each sides of the bubble. Collision of the vibration waves with the bubble imparts the compression pressure to the bubble. This effect is used to dissolve a gas forming the bubble into the liquid phase or to improve liquid quality of this liquid phase.
