Abstract
A number of commercially available cultures, marked for human consumpt ion, were analyzed for viability using a resuspension medium consistin g of KH2PO4, Na2HPO4, cysteine, Tween 80, agar, and an antifoam agent together with modifications of multiple-layer diffusion techniques. Th ese method's were compared to the use of MRS plus cysteine, acidified MRS, End M17 culture media and found to be superior in the selection a nd enumeration of dried cultures of mixed genera.
