Yeast Extract is a spray-dried, autolyzed yeast derivative used as a complex nutrient source in microbiological culture media. It provides peptides, free amino acids, water‑soluble vitamins (notably B‑complex), nucleotides, minerals, and carbohydrates that serve as nitrogen and carbon sources for microorganisms.

It is commonly incorporated into media formulations such as LB, 2×YT, tryptic soy, and YPD for the cultivation and maintenance of bacteria and fungi, including Escherichia coli, Bacillus, and lactic acid bacteria (e.g., Lactobacillus spp.). It is also used in fermentation processes and in media for recombinant DNA workflows where defined antibiotics or inducers may be included separately as required by the protocol.

Yeast Extract is water‑soluble and is typically sterilized by autoclaving as part of complete media preparations. Store in a cool, dry place with the container tightly closed to protect from moisture.

  • Yeast Extract
  • Microbial Culture Media Preparation: Primary nitrogen, vitamin, and peptide source in LB, 2xYT, TB, SOC, and Nutrient Broth for robust growth of Escherichia coli, Bacillus subtilis, yeasts, and fungi.

  • Recombinant Protein Expression: Supports high-density cultures of Escherichia coli for IPTG- or autoinduction-based protein production.

  • Plasmid DNA Production: Enhances plasmid yield in Escherichia coli using LB/2xYT/SOC in cloning and midiprep/maxiprep workflows.

  • Phage Propagation: Component of SOC/2xYT for efficient M13/λ phage amplification in Escherichia coli.

  • Agar and Plate Media Supplementation: Nutrient source in LB agar, YT agar, and selective antibiotic plates for colony isolation and screening.

  • Fermentation and Scale-Up: Enriches seed trains and fed-batch fermentation for bacterial and yeast biomass and metabolite production.

  • Enrichment of Fastidious Microbes: Supplement to minimal media to support auxotrophs and lactic acid bacteria such as Lactobacillus.

  • Streptomyces and Secondary Metabolite Production: Used in actinomycete media for growth and antibiotic/secondary metabolite biosynthesis by Streptomyces.

  • Microbiological QC and Bioburden Testing: Included in general-purpose media to recover stressed or low-viability organisms in environmental and process monitoring.

  • Starter Cultures and Seed Banks: Provides consistent nutrients for preparing glycerol stocks and seed cultures of Escherichia coli and other microbes.
