Product Description & Summary
RCB is a enriched non-selective broth medium formulated by Hirsch and Grinstead to enhance the growth of clostridia from a small inoculum. Casein, beef extract, and yeast extract form the nutritive base that supplies a source of carbon, nitrogen, vitamins, and minerals. Dextrose is added as a source of carbohydrates. L-Cysteine is included as a reducing agent. Soluble starch is a detoxifier of metabolic by-products while sodium acetate acts as a buffer. Resazurin is added as an indicator of significant oxygen exposure to the media. This media is prepared, dispensed, and packaged under oxygen-free conditions to prevent the formation of oxidized products prior to use.
Interpretation of Results & Limitations
If used properly, RCB will support the good growth of Clostridia and many other anaerobes isolated from clinical or non-clinical specimens.
RCB will not provide complete information for identification of bacterial isolates. Additional test procedures and media are required for complete identification. Consult reference materials for additional information.
