Abstract:
A surface plasmon resonance sensor apparatus includes a common substrate, a surface emitting laser, such as a VCSEL, arranged on the common substrate, a sensor array, such as CCD array, arranged on the common substrate, a light-transmitting medium provided above the common substrate, and a metal thin film formed on the light-transmitting medium to cause surface plasmon resonance due to light which is emitted from the surface emitting laser, transmitted through the light-transmitting medium and impinging on the metal thin film. The surface emitting laser, metal thin film and sensor array are positioned such that a change in an intensity of light reflected by the metal thin film caused by the surface plasmon resonance can be measured by the sensor array.
Abstract:
An apparatus for degrading a pollutant to purify a medium containing a pollutant using a microorganism, which comprises a container in which a region containing a microorganism capable of degrading the pollutant is provided, wherein the container has the first opening for introducing the medium into the container and the second opening for draining the medium passed through the region containing the microorganism from the container, and in the container a region containing a functional material which releases a material required for degrading the pollutant by the microorganism is provided between the first opening and the region containing microorganism.
Abstract:
A carrier for supporting microorganisms is characterized by supporting the microorganisms for use in soil remediation, having pores, and holding a nutrient in the pores or being a nutrient for the microorganisms. A soil remediating agent comprises microorganisms having a soil contaminant degrading power and the carrier. A method for remediating a soil comprises administering the soil remediating agent to the soil.
Abstract:
A method of biologically decomposing a phenolic compound or a furan compound has the step of decomposing a phenolic compound or a furan compound by bringing an aqueous solution containing the phenolic compound or furan compound into contact with microorganisms derived from the intestine of a termite and having the ability to decompose the phenolic compound or furan compound. The microorganisms having the ability to decompose the phenolic compound or the furan compound is obtained by culturing the microorganisms isolated from the intestine of a termite in a medium containing as a single carbon source the phenolic compound or the furan compound, and recovering the microorganisms grown.
Abstract:
A method of biodegradation of a polluting substance by a microorganism is disclosed, wherein the microorganism is an auxotrophic microorganism and the action of the auxotrophic microorganism is controlled by the amount of a required nutrient for the auxotrophic microorganism. A carrier for supporting an auxotrophic microorganism for use for biodegradation contains a required nutrient for the auxotrophic microorganism.

Abstract:
A method for forming an oligonucleotide comprises the steps of synthesizing a pair of oligonucleotides, one loigonucleotide having a base sequence portion comlementary to that of the other at a part of the terminal end region thereof; binding the pair of oligonucleotides at the complementary base sequence portions; and polymerizing nucleic acid bases onto the resulting pair of oligonuceotides. the mathod may further comprise the step of separating the oligonucleotides thus obtained into single strands.
Abstract:
There are provided a method and an apparatus for measuring an immunologically active material by physically or chemically immobilizing material immunologically active to a material to be measured of a specimen to the dehydrated solid fine particles, providing a desirable dispersion comprising said immunologically active material immobilized to said solid fine particles and said specimen in a liquid medium, reacting them to cause a reaction mixture in an agglutinated state and optically measuring said agglutinated state of the reaction mixture to thereby quantitatively determine the content of said material to be measured with an improved accuracy.
