Usage

Description

Proteose-Peptone is a highly nutritious peptone prepared from a mixture of peptones rich in peptides with higher molecular weight. It is a hydrolysate obtained by partial digestion with pepsin and serves as a vital component in various culture media for the cultivation and testing of microorganisms.

Uses

Used in Microbiology:
Proteose-Peptone is used as a component in general purpose culture media for the routine cultivation of a variety of microorganisms. It provides essential nutrients required for their growth and maintenance.
Used in Bacteriological Applications:
Proteose-Peptone is used as a component in Ax-2 axenic medium to induce reproduction of Dictyostelium discoideum, a type of slime mold used in biological research.
Used in Mycological Applications:
Proteose-Peptone is used as a component in phospholipase agar plates for phospholipase assay, a test used to identify certain types of bacteria based on their ability to break down phospholipids.
Used in Sterility Testing:
Proteose-Peptone is specified by the United States Pharmacopeia (USP) for sterility testing, ensuring the absence of viable microorganisms in various products.
Used for Growth of Streptococci:
Proteose-Peptone is recommended for the growth of Streptococci, a group of Gram-positive bacteria, in culture media.
Used for Detecting Hydrogen Sulfide-Forming Microorganisms:
Proteose-Peptone is used in culture media for detecting hydrogen sulfide-forming microorganisms, which are bacteria that produce hydrogen sulfide as a metabolic byproduct.

Biochem/physiol Actions

Peptone supplementation in media helps to increase cell number, specific monoclonal antibody production and also the period of long term culture.
