| Application: | Tryptone is recommended for laboratory media and fermentation and has been used in antibiotics, toxins, and enzyme productions. It is also used as a nutrient in vaccine production where a high free amino acid content is required. Tryptone may also be used in STGG (skim milk, tryptone, glucose, glycerol) medium at -80°C, which is used to preserve Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates for at least 3 years. |
| General description: | Tryptone is a general-purpose growth peptone obtained from vegetable source and meat-free alternative to enzymatic digest from casein. It is used as a nitrogen source in culture media formulated for isolating and cultivating fastidious and non-fastidious bacteria, fungi, and some protozoa. It is a refined hydrolysate with high solubility and is used as a microbiological nutrient in laboratory media and fermentations. It is a high-quality source of amino acids and peptides produced by the pancreatic digestion of casein. |
