Thermo Fisher, PB0225A, Fastidious Anaerobe Agar (F.A.A.) with Horse Blood

Unit Size: Each
Fastidious Anaerobe Agar (F.A.A.) with Horse Blood is a medium for the growth of fastidious organisms. The peptones included have been chosen for maximum growth stimulation. Starch and sodium bicarbonate act as detoxification agents while haemin encourages pigment production in Porphyromonas melaninogenicus. Specific growth promoting agents are Cysteine for Fusobacterium necrophorum, Propionibacterium acne and Bacteroides fragilis, arginine for Eubacterium spp., and soluble pyrophosphate for Porphyromonas gingivalis and Porphyromonas asaccharolyticus. Pyruvate helps neutralize hydrogen peroxide and is also utilized by Veillonella spp. as an energy source. Vitamin K and sodium succinate provide essential growth factors for some anaerobes, as does the 0.1% glucose. The low level of glucose prevents the production of high levels of acids and alcohols which would inhibit colonial development.
