  • Patent number: 7432073
    Abstract: The present invention relates to a method capable of detecting proliferative bacteria in food and beverage, particularly acid or neutral beverage at low cost within a short time, a detection kit which enables simple measurement, and a technology for examination of harmful bacteria in food and beverage with respect to a method for rapid determination of proliferation properties of bacteria capable of producing guaiacol in food and beverage. There is disclosed a method for detecting bacteria capable of producing guaiacol, which comprises culturing or incubating a culture solution containing a specimen for a predetermined time in the presence of vanillic acid, and measuring the produced guaiacol by qualitative or quantitative analysis. Also there is disclosed a kit for detection of bacteria capable of producing guaiacol, comprising a container, and an acid or neutral culture medium containing a vanillic acid substrate for production of guaiacol, which is contained in the container and also sterilized and sealed.

  • Patent number: 5480804
    Abstract: A microorganism detecting apparatus comprising a fluorescence microscope section which is furnished with a motor-driven stage for placing thereon a microorganism sample subjected to fluorescent staining, and a light source portion for projecting excitation light of predetermined wavelength on the sample; a detection section which detects and photoelectrically converts fluorescence of specified wavelength from the microorganism sample at a position posterior to the microscope section; a filter unit which limits the band of frequencies ascribable to noise in relation to an electric signal from the detection section; a signal processor which reads the output value of the band-limited signal from the detection section, and which processes the read output value; and an automatic inspection section which drives the stage so as to permit the microorganism sample to be scanned over its whole area, and which stores each signal detection part in the sample so as to permit a fluorescent substance at the part to be verif
