Abstract: A method for testing a microorganism to simultaneously judge the presence or absence of plural types of microorganisms in environment includes collecting the microorganism floating in air in a liquid; extracting nucleic acids from the microorganism in the liquid; amplifying part of the nucleic acids extracted; and identifying the type of the microorganism when nucleic acids that bind complementarily with the amplified nucleic acids are immobilized on a carrier after dropping a solution containing the amplified nucleic acids to the carrier, wherein nucleic acids of the plural types of microorganisms are immobilized in advance, and wherein culturing of the microorganism is not conducted after the collecting and before the extracting.

Abstract: [PROBLEMS] To provide a heating electrode which can uniformly heat a material to be heated having an irregular shape and can stably perform heating/holding-convey of the material to be heated by the heating electrode; and a method for heating food by using the heating electrode. [MEANS FOR SOLVING PROBLEMS] An assembly of pin electrodes (10) formed by conductive pins are slidably arranged in a through hole (21) of a pin support table (20). A pressure-variable gas chamber (30) whose pressure is variable is connected to the pin support table (20). By applying a plus pressure or a minus pressure to the gas chamber (30), the pin electrodes (10) are displaced relatively to the pin support table (20).
