Суточная инкубация бактерий в присутствии высокой концентрации БАВ (1200–20 000 мкг/мл) приводила к снижению их количества, в концентрации 600–300 мкг/мл ингибирующий эффект не проявлялся, 150 мкг/мл – способствовала росту штаммов E. coli. Такая же тенденция наблюдалась в отношении бактерий в составе биопленок: цинка аспартат в концентрации 2500 мкг/мл оказывал бактерицидное влияние на S. aureus и E. Coli. Это позволяет рассматривать БАВ в качестве вспомогательных веществ для повышения эффективности антибактериальных препаратов и указывает на необходимость дальнейшего изучения более широкого круга низкомолекулярных соединений.</p></abstract><trans-abstract xml:lang="en"><p> Biologically active substances (BAS) (tryptophan, zinc aspartate, arginine, tatipacin, taurine) have modulating effects on the metabolism of microorganisms in vitro. The study found that biologically active substances have dose-dependent effects on the metabolic activity of bacteria in planktonic form. Daily incubation of bacteria in the presence of a high concentration of biologically active substances (1200–20 000 μg/ml) led to a decrease in the number of planktonic forms. BAS concentrations in the range of 600–150 μg/ml did not have an inhibitory effect on microorganisms. All test substances at a concentration of 150 μg/ml promoted the growth of E. coli strains. Dose-dependent effects of biologically active substances were also observed in relation to bacteria in biofilms. Zinc aspartate at a concentration of 2500 µg/ml has a bactericidal effect on S. aureus and E. coli in monobiofilms. The identity of metabolic flows leads to competition between body cells and microorganisms for nutrient substrates, which is important in the development of the infectious process, and also indicates the need to study the effects of biologically active substances in animal models.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биологически активные вещества</kwd><kwd>антибактериальный эффект</kwd><kwd>S. aureus</kwd><kwd>E. coli</kwd><kwd>планктонные формы</kwd><kwd>микробные биопленки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biologically active substances</kwd><kwd>antibacterial effect</kwd><kwd>S. aureus</kwd><kwd>E. coli</kwd><kwd>planktonic forms</kwd><kwd>microbial biofilms</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">D.
