Yeast Extract is a water‑soluble autolysate of Saccharomyces cerevisiae that supplies peptides, amino acids, nucleotides, vitamins, and trace elements. It is used as a complex nitrogen and growth factor source in microbiological media for the cultivation of bacteria and yeasts, and is a standard component of LB, 2xYT, TSB, MRS, and related complex media. It supports routine propagation of heterotrophic bacteria such as E. coli, Bacillus, Staphylococcus, Pseudomonas, Enterococcus, and lactic acid bacteria including Lactobacillus.

Typical uses include culture media preparation for propagation, selection, and maintenance of microbial strains; fermentation of metabolites and recombinant proteins; diagnostic media and quality control testing; food and dairy microbiology; and environmental microbiology. It dissolves readily in water and is commonly sterilized by autoclaving when included in complete media or by membrane filtration in heat‑sensitive solutions. Store the dry product in a cool, dry place with desiccant protection.

  • Yeast Extract
  • Microbial Culture Media Preparation: Complex nutrient source in LB, TB, 2xYT, and MRS media to support growth of E. coli, Bacillus subtilis, and lactic acid bacteria.

  • Recombinant Protein Expression: Supports high-density cultivation of E. coli for plasmid and protein production.

  • Industrial Fermentation: Nutrient supplement for production of enzymes, amino acids, and vitamins in bacterial fermentations.

  • Antibiotic Discovery and Production: Used in media for cultivating Streptomyces and other actinomycetes during secondary metabolite screening.

  • Probiotic and Dairy Culture Propagation: Supports growth of Lactobacillus spp. and Streptococcus thermophilus in starter and maintenance media.

  • Microbial Enumeration and Quality Control: Component in general-purpose media for environmental monitoring and bioburden testing, including Salmonella and Staphylococcus aureus recovery.

  • Seed Train Development: Supplement for seed cultures to improve biomass accumulation prior to scale-up.

  • Phage Work and Cloning: Enhances host cell growth (e.g., E. coli) in phage amplification and molecular cloning workflows.

  • Food and Beverage Microbiology: Ingredient in culture media for detecting and enumerating spoilage and pathogenic bacteria.

  • Analytical Media Formulation: Used in selective and differential media to recover stressed or fastidious bacteria.
