Product Description & Summary
YCFAC is an enriched nonselective media used in the isolation and cultivation of a wide variety of bacteria found in the human gut, including Faecalibacterium prausnitzii. The basic nutritive components of this media come from yeast extract and pancreatic digest of casein. This basal medium is then enriched with various specific vitamins, sugars, and fatty acids to ensure growth of even the most fastidious gut microbes. 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, YCFAC BROTH supports good growth of many fastidious and non-fastidious anaerobes isolated from clinical specimens.
YCFAC Broth 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.
