Abstract

To grow up bacterial cultures for biotechnology, it is necessary to select for them suitable nutrient mediums. The purpose of researches was definition of use?s possibility of a fermentative hydrolyzate from sub-standard eggs as nutritious broth for cultivation of various groups of microorganisms. The experimental liquid environment prepared on the basis of a fermentative hydrolyzate of sub-standard eggs (FHSSE) with the content of amines nitrogen (% Nam) from 480 to 570 mg %. For check of ability to support growth of microorganisms the received nutrient mediums on the basis of an egg?s hydrolyzate and beef- extract broth (control) inoculated with cultures: Bacillus subtilis ATCC 6633, Escherichia coli and Lactobacillus acidophilus . By us it is established that nutrient mediums on the basis of FHSSE provide growth of Bacillus subtilis ATCC 6633, Lactobacillus acidophilus, Escherichia coli , the number of cages of the microorganisms doesn?t fall below value of colonies forming units-106. Thus, the received results of researches showed that nutrient mediums on the basis of various options of a fermentative hydrolyzate can serve for accumulation, allocations and subcultivation of various groups of microorganisms and sub-standard eggs can serve as a full substitute of meat raw materials or fish products in production of nutritious bases.
