United States Biological Corporation BACTO YEAST EXTRACT 500G
Aqueous extract of brewers yeast with an exceptionally high vitamin content. Selected for greater solubility and clarity. Free amino acid content of approximately 25%. Yeast Extract is produced from autolyzed yeast cells and is very soluble in water. It is used as an enrichment in a large number of culture media for general bacteriology and in media for sterility according to the USP. Because of its high content of carbohydrates, Yeast Extract should not be used in fermentation studies. Typical Amino Acid Profile: Ala 42%, Arg 27%, Asp 59%, Cys 5%, Glu 105%, Gly 27%, His 12%, Ile 28%, Leu 42%, Lys 45%, Met 9%, Phe 24%, Pro 21%, Ser 27%, Thr 28%, Trp 6%, Tyr 21%, Val 36% Appearance: Light yellow to medium tan, homogeneous, free flowing powder Solubility: Light yellow to amber, clear, complete pH: 6.5 � 0.5 Ash: 17% Salt: 0.5% Nitrogen (Amino): 5% Nitrogen (AN/TN): 36% Microbiological Testing: Salmonella, Standard Plate Count, Coliform (MPN/g), Viable Yeast & Mold.

Pancreatic digest of casein used to supplement media in cultivation of anaerobic bacteria. pH (1% solution): 7.3. Ingredients: Molecular Biology GradeTotal Nitrogen (TN): ~12.7% Amino Nitrogen (AN): ~3.7% AN/TN Ratio: 0.26 Sodium Chloride: ~0.4% Tryptophan: ~1.0
AG Scientific Inc Tryptone, Powder, 500 G
Tryptone is an assortment of peptides formed by the digestion of casein by the protease trypsin. This digest can act as a source of nitrogen and amino acids for microorganisms and is used to supplement media in the cultivation of bacteria and fungi (particularly anaerobic bacteria). It has high levels of free amino acids, particularly an abundance of tryptophan. Tryptone has no detectable carbohydrates, thus It is useful for differentiation of bacteria based on their ability to ferment carbohydrates.CAS Number: 91079-40-2Solubility: Freely soluble in distilled/purified water, insoluble in alcohol and ether.Storage Temperature: Room TemperatureResearch or further manufacturing use only, not for food or drug use.
