Most Probable Number (MPN) tests using Tryptic Soy Broth (TSB) are used to estimate the total aerobic bacteria count of a sample. MPN tests using TSB are commonly used in sterility testing for products that are not sterile and for checking the amount of bacteria in food and water. MPN testing is especially useful when the sample has particles that make other counting methods difficult.
Tryptic Soy Broth is also widely used in laboratories for cultivating microorganisms It is a general-purpose liquid medium that supports the growth of many types of bacteria and fungi. It is non-selective and allows a wide variety of microorganisms to grow, including fastidious bacteria (those with special growth requirements), such as Streptococcus, Neisseria, Listeria, Haemophilus, Vibrio, Corynebacterium, and Brucella as well as common bacteria like Staphylococcus aureus and Escherichia coli and Yeasts and molds.
In as little as 45 minutes, ToxTrak allows you to evaluate toxicity in a sample. Applicable to both drinking water and wastewater, ToxTrak measures and compares the toxicity of a sample to a baseline using either indigenous biomass or stock bacteria cultures.
Toxicity is monitored using several methods, such as growth, specific enzyme activity, bioluminescence, and respiration. These methods may require lengthy incubation times, centrifugation, solvent extraction, laborious colony counting procedures, and expensive equipment. With the ToxTrak Toxicity Test, you use a simple colorimetric method to determine the inhibitory effects of a waste stream on bacteria. With a photometer, you can monitor large numbers of samples quickly and inexpensively.
Cut costs in your laboratory by using ToxTrak to screen for potentially toxic influents and effluents. Or use it to identify dilutions for long-term bioassays. Long-term bioassays can require two to seven days to complete and are costly to perform.

ToxTrak is an inexpensive alternative that has results comparable to respirometric methods measuring dissolved oxygen consumption. You can use ToxTrak to screen influent and effluent and/or process waters. ToxTrak is also a useful tool for evaluating fluctuations in drinking water quality caused by intentional or accidental contamination.
