Prepared Plated and Tube Culture Media

Prepared Plated and Tube Culture Media offers the following pre-plated medium types: tryptic soy agar, tryptic soy agar with 5% sheep blood agar, MacConkey Agar, and Sabouraud dextrose agar (deep fill). Media containing dies should be protected from the light. The ideal range of storage temperatures for pre-plated media is 2-8°C.

As noted, tryptic soy agar can be purchased with or without blood enrichment. This general growth media is used to isolate fastidious microorganisms.

MacConkey Agar is used to inhibit Gram positive bacteria through the use of a bile salts mixture and crystal violet. The agar formulation allows for the isolation, differentiation, and enumeration of MacConkey Enterobacteriaceae and other Gram negative bacteria.

Sabouraud Dextrose Agar is a medium used for the isolation, identification, and cultivation of fungi. As no inhibitors are included, Sabouraud Dextrose Agar is appropriate for fungi that are susceptible to antibiotics.

Weber Scientific offers pre-prepared tryptic soy broth tubes. Tryptic soy broth includes casein peptone and soy peptone. This enhances the growth of a wide variety of organisms without the addition of blood or serum. Both fastidious and non-fastidious organisms can be grown in tryptic soy broth.
