[The possibility of using a bacteriological peptone from whole blood as the nutrient base for growing microorganisms]. / Izuchenie vozmozhnosti ispol'zovaniia bakteriologicheskogo peptona iz tsel'noi krovi kak pitatel'noi osnovy dlia vyrashchivaniia mikroorganizmov.

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.

[The production of a protein base for nutrient media from a dairy industry byproduct]. / Poluchenie belkovoi osnovy dlia pitatel'nykh sred iz subprodukta molochnoi promyshlennosti.

The technology of obtaining protein hydrolysate, a by-product of butter making, has been developed. This hydrolysate has been successfully tested as protein base for the preparation of culture media used in the quality control of foodstuffs and the diagnosis of infectious diseases.
