[The possibility of using a bacteriological peptone from whole blood as the nutrient base for growing microorganisms]

Study of some parameters of the process of hydrolysis in addition to other experiments has made it possible to develop a method for obtaining a nutrient base for the cultivation of microorganisms with the use of cattle whole blood as protein substrate and papain as a hydrolyzing agent. The product thus obtained is characterized by high levels of amino and total nitrogen (4% and 14% respectively). Biological studies with the use of this product in different culture media and observations on the growth and characteristics of many microbial strains have shown the possibility of its use for the diagnosis of infectious diseases, for the control of the quality of foodstuffs and water.
