GBP Peptone, Powder is a rich nitrogen source benefited from a high concentration of free amino acids and short-chain peptides from pancreatic digest of milk casein, supporting the optimal growth of your microbes. During its production, proteins are enzymatically digested and broken down into smaller peptides and amino acids. This hydrolysis process makes the nutrients in peptone more readily available for microbial metabolism and growth. The composition and quality of peptone can vary depending on the source and production methods. Different types of peptones are available, each with its specific nutrient profile and suitability for particular microorganisms or applications.
