Tryptose is a mixture of enzymically digested protein. It is designed to promote luxuriant growth of highly fastidious microorganisms. Even though enzymically digested, it can be successfully employed in place of meat infusion to meet the nutritional requirements of fastidious microorganisms. It is a light yellow coloured powder that forms crystal clear aqueous solution. It is used in following media. Tryptose Media – for cultivation of fastidious microorganisms and for preparing Blood Agars. Since the blood cells are maintained in an excellent state in Tryptose Media, haemolytic reactions can be easily demonstrated. Vaccine preparation media – for rapid and luxuriant growth as desired for large scale manufacturing of vaccines and toxins.
