Super broth media, commonly referred to as SB broth, is a rich bacterial culture medium formulated with peptones (or alternatives), yeast extract, and buffering components that support robust bacterial growth. This nutrient-dense formulation promotes high cell densities and strong culture performance during extended incubation.

Super broth media is most commonly used to culture E. coli and other non-fastidious bacterial strains employed in cloning, plasmid propagation, and recombinant DNA workflows. Compared to standard LB broth, bacteria grown in super broth media often reach higher cell densities, supporting improved yields in downstream molecular biology and biotechnology applications.

Our super broth media, including formulations with animal-free soytone or without glucose, are supplied as a ready-to-use liquid medium, eliminating in-house media preparation and reducing variability. Each formulation is manufactured to precise specifications to ensure consistent nutrient availability and reproducible bacterial growth.

We manufacture our full catalog of super broth media using validated processes and rigorous quality control testing to ensure performance and lot-to-lot consistency. We also support custom manufacturing options, including modified super broth formulations, antibiotic supplementation (up to 5), alternative fill volumes, peptones, and bulk container formats to support specialized molecular biology and biotechnology workflows.
