摘要： A method for detecting microorganisms present in a sample comprises the steps of: applying a non-lethal hydrostatic pressure to a sample containing microorganisms; and staining the microorganisms with a fluorescent dye. The method permits a significant increase in the uptake of a fluorescent substance by applying, to a sample, a desired non-lethal hydrostatic pressure, without causing any reduction of the survival rate of microorganisms. The method also permits the elimination of such a secondary effect that the subject microorganism undergoes proliferation during staining the same with a fluorescent dye. Thus, the present invention would contribute to the determination of the correct viable count in a wide variety of technical fields.

摘要： Methanosarcina alcaliphilum which is alkalophilic methanogen having the optimum growth pH range of from about 8.1 to about 8.7. This strain exhibits excellent properties such as alkalophilicity and resistance to low temperature. This strain makes it possible to carry out methane fermentation methods at an alkaline pH and at a low temperature conditions. This strain is applied to methane fermentation in treating solid waste and waste water. Moreover, the bacterial concentration thereof in a reactor can be increased within a very short time and, therefore, the size of such a reactor can be made compact.

摘要： This invention provides a novel process for producing cyclodextrin by reacting cyclodextrin glycosyl transferase having an optimum pH on the alkaline side with gelatinized starch. According to this invention, cyclodextrin can be obtained in the form of a pure crystal in a high yield by reacting a glucomylase with the reaction mixture liquid formed by the above enzymatic reaction to decompose unreacted starch, concentrating the liquid, adding a small amount of cyclodextrin as a seed crystal and recovering the precipitated cyclodextrin.
