In 1955, Leavitt et al. discovered that Tryptic Soy Agar facilitated vigorous growth of aerobic and anaerobic microorganisms. This is an enriched media, suitable to support fastidious heterotrophs.
Selective medium for the enumeration of fungi. This formula is prepared with a neutral pH and supplemented with chloramphenicol as the selective agent in fungal medium.
Tryptic Soy Agar is recommended in multiple water & wastewater applications, and numerous standard methods for food testing. TSA is commonly used as a maintenance medium for culture collections and testing bacterial contaminants in cosmetics. Rose Bengal Chloramphenicol Agar is recommended in Standard Methods for the Examination of Water and Wastewater for the enumeration of yeasts and molds from foods and water.
Using the LaMotte Cyanide in Water Test Kit, the cyanide is first reacted with a chlorine donor to form cyanogen chloride, which then reacts with pyridine-barbituric acid to form a red-blue color. Levels are determined using the Octa-Slide 2 comparator.
This Biological Activity Reaction Test tests for heterotrophic aerobic bacteria. Test kit includes nine tests. The change of blue color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
This Biological Activity Reaction Test tests for Iron related bacteria. Kit includes 9 tests. The change of red color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
This Biological Activity Reaction Test tests for Sulfate Reducing Bacteria. Kit includes nine tests. The change of black color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
This Biological Activity Reaction Test tests for Slime Forming Bacteria. Kit includes nine tests. The change of lime green color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
