Storage Temperature: +15 °C to +30 °C
Peptone acid hydrolysate is prepared by acid hydrolysis of vegetable proteins and is suitable for use in culture media requiring an amino acid mixture. Its growth promotional characteristics match with casein acid hydrolysate.
It can be used for preparing antibiotic sensitivity test media, in media requiring quantitative addition of tryptophan and in vaccine preparation media as a source of high concentration of free amino acids.
