Alkali Scientific Bordet Gengou w/15% Sheep Blood 20mL Plate, 10/Pk
Bordet Gengou Agar with 15% Sheep Blood is a highly enriched medium developed for the isolation and identification of Bordetella pertussis and Bordetella parapertussis. Each sterile 100 × 15 mm plate contains 20 mL of potato infusion agar supplemented with glycerol and 15% defibrinated sheep blood. The potato infusion provides essential nutrients while starch components absorb inhibitory fatty acids that could hinder growth. This formulation supports the recovery of fastidious Bordetella organisms from respiratory specimens. Colonies typically appear smooth, convex, and glistening with a characteristic “mercury drop” appearance. The high blood concentration supplies additional growth factors and allows observation of colony morphology. This medium is widely used in clinical microbiology laboratories for diagnosing whooping cough infections.
Alkali Scientific DNAse est Agar w/Methyl Green 20mL Plate, 10/Pk
DNase Test Agar with Methyl Green is a differential microbiological medium used to detect the production of deoxyribonuclease (DNase) enzymes by bacteria. Each sterile petri dish contains approximately 20mL of nutrient agar incorporating polymerized DNA and the indicator dye methyl green. The dye forms a stable complex with intact DNA, producing a green colored medium. When microorganisms that produce DNase grow on the surface, the enzyme breaks down the DNA molecules surrounding the colony. As the DNA degrades, the methyl green is released, creating a clear halo around DNase positive colonies. This reaction allows rapid visual differentiation of organisms such as pathogenic Staphylococcus species and certain Gram negative bacteria in clinical microbiology laboratories.
Alkali Scientific Dichloran Glycerol DG18 (ACGIH) 20mL Plate, 10/Pk
Dichloran Glycerol (DG18) Agar is a selective low water activity medium used for the enumeration of xerophilic molds and osmophilic yeasts. Each sterile petri dish contains approximately 20mL of nutrient agar supplemented with 18% glycerol and the antifungal agent dichloran. The high glycerol concentration lowers the water activity of the medium, creating conditions favorable for organisms that thrive in dry environments such as flour, spices, cereals, and dried foods. Dichloran limits the spreading growth of rapidly growing molds, allowing slower growing colonies to remain visible and countable. Because of these properties, DG18 agar is widely recommended for environmental monitoring, indoor air investigations, and food microbiology testing where detection of xerophilic fungi is required.

Alkali Scientific Nitrate Broth 5mL Tube, 10/Pk
Nitrate Broth is a differential medium used to determine whether microorganisms can reduce nitrate to nitrite or further nitrogenous compounds through nitrate reductase activity. This biochemical test is commonly used for identification of Gram negative bacteria including Enterobacteriaceae, Pseudomonas, and certain Mycobacterium species. Each 5 mL tube contains nutrient broth supplemented with potassium nitrate. After incubation, reagents containing sulfanilic acid and alpha naphthylamine are added to detect nitrite production. A red color indicates a positive nitrate reduction result. If no color appears, zinc dust may be added as a confirmation step to determine whether nitrate remains unreduced or has been reduced beyond nitrite. The test provides valuable metabolic information for bacterial identification.
