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.

Abstract: An information retrieval apparatus features a three-dimensional display unit for displaying a set of indexes controlling attributes of a database in a three-dimensional image space in sight of a user with index display images so as to allow the user to visually recognize the set of indexes. An input unit detects motion patterns of the user's body against the index display images as input information and displays the motion patterns in the three-dimensional image space. An arithmetic operation unit recognizes the input information of the motion patterns received through the input unit and performs set logical operations of selected images in accordance with the motion patterns so as to collate and retrieve information from the database. The user can further directly operate index display images in a three-dimensional image space or a two-dimensional image space without the necessity of a keyboard and recognize input information with his body's motion patterns.
