Latest Patents
One of Sugiyama's latest patents is a method for the production of trehalose using strains of Micrococcus. This innovative approach involves cultivating a microorganism belonging to the Gram-positive cocci, which has a guanine plus cytosine content of DNA of not less than about 55 mol %. The method allows for the production and extracellular accumulation of trehalose in a medium with a good yield, making it a feasible option for industrial production. The preferred microorganisms for this process include Deinococcus proteolyticus, Deinococcus erythromyxa, Deinococcus radiopugnans, Micrococcus varians, Micrococcus agilis, and Microccus luteus.
Another significant patent by Sugiyama focuses on producing polyglutamic acid or a salt thereof. In this fermentive production process, the accumulation of polyglutamic acid can be markedly increased by adding an alkaline earth metal ion to the medium in a concentration of not less than 0.05 mole per liter. This method simplifies the production process and enhances yield.
