On the use of the main nutrient medium from cottage cheese for growing microbes

Abstract

The main condition for the suitability of a nutrient medium for growing microbes is the presence of protein substances in it. Research thought so far has been in the direction of replacing animal protein with vegetable protein. We see this in a large number of German recipes, the so-called. Ersaznährböden (surrogate environments). In order to find the most complete replacement of animal proteins in bacteriological nutrient media, the composition of many nutrients was determined in detail. Soy proteins turned out to be the closest in composition to animal proteins. Since soybeans are not widespread in all regions of the Soviet Union, Russian researchers had to look for other sources of raw materials, more accessible than soybeans. The Scientific Medical Institute proposed nutrient media from peas. But, apparently, these media are not always suitable (Calc), if only in view of the limited number of generations obtained for the p-p of some pathogenic bacteria (bang. Shiga dysentery), the absence of pigment formation (miraculous rod).
