SCDM (Soybean-Casein Digest Medium)

A general-purpose medium, also called tryptic soy broth (TSB) or tryptic soy agar (TSA), that supports a wide range of bacteria and fungi. The broth is used in sterility testing at 20–25 °C and in media fills, and the agar is used for TAMC in MLT and for environmental monitoring, often with added neutralisers. It is also the enrichment broth in USP <62> tests for specified organisms.
