Product Code: LAB071
F.A.B. was developed by Lab M working in conjunction with the microbiology department of a University of Manchester teaching hospital.
The medium was designed to give optimum growth of fastidious anaerobes and has found applications as a blood culture medium and an enrichment broth for the isolation of anaerobes. The medium is very rich in nutrients from the specially selected peptone mixture. Vitamin K. haemin and L-cysteine are all growth factors required by some anaerobes. L-cysteine together with sodium thioglycollate reduce the Eh of the medium and the agar content inhibits absorption of oxygen and convection currents. Resazurin is a redox indicator. Several published evaluations show F.A.B. to be the liquid medium of choice for fastidious anaerobes.
