    摘要： In one aspect the invention provides a system for detecting the presence of toxins in a sample that includes a plurality of chambers for culturing organisms and observing the organism's motility response when introduced into a sample containing a toxin. The toxicity measurement system may include an imaging module to monitor and track the movement of one or more organisms in the sample and identify abnormalities. In other aspects, the invention provides methods of culturing organisms and detecting the presence of toxins in the sample using the motility response of organisms in the sample.

    摘要： According to the method of treating water in a cooling water system, adhesion of fouling is on-line monitored by a compact and inexpensive apparatus and a slime control treatment is intensified according to the result of on-line monitoring. The water treatment is intensified in response to the change of electric potential of a sensor monitoring microbial fouling 11 made of sensitized metallic material. When the electric potential of the sensor exceeds a threshold value, an agent is added through both chemical feeding pumps 15 and 17. When the electric potential lowers to the normal value, the agent is added only through the pump 15.

    摘要： A method of determining denitrification time for at least a portion of wastewater in a wastewater treatment process including isolating a wastewater sample from the wastewater in the wastewater treatment process; detecting changes in fluorescence emitted by NADH from microorganisms contained within the sample; detecting changes in pH of the sample; analyzing the changes in NADH and pH and establishing that the sample is denitrified at a point where NADH shifts from a steady state or a decreasing state to an increasing state and, substantially simultaneously, the pH shifts from a steady state or an increasing state to a decreasing state; and calculating elapsed time between when the sample was taken and when the sample was denitrified to determine the denitrification time for the portion of the wastewater treatment process.

    摘要： A portable toxicity tester for use in the field using bioluminescent organisms consisting of a light tight container for housing the necessary flash of light detecting apparatus and the necessary signal processing circuits, digital readout and control panel. A light tight chamber is provided with a removable stirrer assembly which is the stirrer motor housing as well as the light tight cover for the chamber. With the cover removed, a vial containing the necessary inoculated bioluminescence organisms is inserted into a holder in the chamber. Part of the stirrer assembly is a paddle attached to the motor shaft that extends to near the bottom of the vial. The top of the vial holder extends beyond the outer surface of the cover to insure a light tight seal.

    摘要： A method for monitoring the formation of biofilm on surfaces which are exposed to a flowpath of liquid essentially containing water includes flowing a liquid along the flowpath only once without being circulated through a tube section, through and along a series of sample tube pieces removably placed within the tube section, successively removing the sample tube pieces without replacement each time after a period of flow elapses and testing the sample pieces removed to determine the biofilm formation thereon. The tube section is arranged essentially vertically, and the flow through the tube section is downwardly directed, the uppermost sample tube pieces being removed in succession after each time period of flow exposure.
