Peptone water is used in the dilution technique because it provides a nutrient-rich environment that supports the growth of bacteria. This allows for easier detection and enumeration of bacteria present in samples. Peptone water also helps maintain bacterial viability during dilution procedures.
There are two Peptone used in TSA media:1. Casein peptone2. Soya peptoneCasein peptone and Soya peptone provide nitrogen, vitamins and minerals. The natural sugars from Soya peptone promote bacterial growth.
This leads to neutral water by H+ + OH- --> H2O and neutral salt solution when added in equavalent amounts, BUT it is NOT a buffered solution.
abbreviation for Neutral Buffered Formalin
Peptone is a protein hydrolysate composed of amino acids and peptides. It serves as a nitrogen source for bacterial growth in a nutrient broth by providing essential nutrients that support bacterial metabolism and protein synthesis. Peptone enhances the growth of bacteria by supplying amino acids that the bacteria need to build proteins.
