High-Quality Nitrogen Source for Microbiological Media
Peptone from Casein, also known as Tryptone, is an enzymatic digest of casein that provides a complex mixture of peptides and free amino acids for microbiological cultivation. It is widely used as a reliable nitrogen source in general-purpose, enriched, and specialised media formulations.
Tryptone is particularly valued for its naturally high level of tryptophan and its low carbohydrate background, making it well suited to media where controlled biochemical performance and strong bacterial growth are required.
Why labs use it
- Rich source of peptides and free amino acids
- Supports broad bacterial cultivation
- High tryptophan content
- Low carbohydrate interference
Typical applications
- General-purpose and defined media
- Culture of bacteria requiring tryptophan
- Reduced-carbohydrate formulations
- Routine microbiology, research, and QC laboratories
Nutritional Characteristics
- Peptides: Readily assimilable nitrogen and carbon sources
- Free amino acids: Including elevated tryptophan content
- Minimal carbohydrates: Suitable for controlled metabolic studies
- Growth-supporting factors: Promote consistent bacterial growth

Technical Overview
Tryptone is obtained by enzymatic hydrolysis of casein and consists primarily of peptides and free amino acids. It is widely used in microbiology laboratories as a high-quality nutrient source, especially where strong growth performance and low carbohydrate background are desired.
Functional Components
- Peptides for readily available nitrogen
- Free amino acids, including tryptophan
- Low carbohydrate content for reduced biochemical interference
- Growth-supporting factors for consistent cultivation
Recommended Applications
- General-purpose microbiological media
- Defined and semi-defined bacterial media
- Media for tryptophan-requiring microorganisms
- Biochemical and metabolic test formulations
Storage and Shelf Stability
- Store at 10–30 °C
- Keep tightly closed after opening
- Protect from moisture and direct light
- Use before stated expiry date
Product suitability should be validated in the end user’s own formulation, process, and target microorganism system.
