Typical Composition
PeptidesDi-, tri-, and oligopeptides from enzymatic hydrolysis — primary nitrogen carriers for rapid microbial assimilation
Free Amino AcidsFull spectrum including glutamine, glycine, alanine, leucine, and lysine; directly utilisable without further digestion
Nitrogenous CompoundsPurines, pyrimidines, and nucleotide precursors supporting DNA/RNA biosynthesis
Minerals & Trace ElementsSodium, potassium, phosphorus, magnesium, calcium, and trace amounts of iron and zinc
Exact composition varies naturally between batches due to the biological origin of the material. A Certificate of Analysis (COA) is available upon request.
Key Features & Benefits
High total nitrogen (≥13%) and amino nitrogen (≥3%) — superior nitrogen bioavailability for demanding organisms
Enzymatic hydrolysis preserves peptide integrity — supports fastidious bacteria that require pre-formed nitrogen sources
Freely water-soluble — dissolves rapidly, simplifying media preparation at all scales
Autoclave-stable — withstands 121°C sterilisation without significant nutritional loss
Batch-to-batch consistency — reliable performance across routine QC, research, and industrial fermentation
Compatible with a wide range of compendial and standard media formulations
Typical Applications
General-purpose microbiological culture media
Cultivation of fastidious bacteria, yeasts & moulds
Vaccine & biological product production
Fermentation & industrial microbiology
Pharmaceutical microbiology & QC testing
Research & compendial media formulations
