В настоящей работе представлены результаты сравнительного хемомикробиомного анализа орнитина и молекул сравнения (S-адеметионина, урсодезоксихолевой кислоты, лактулозы и фруктозы). Для каждой из исследованных молекул были получены оценки значений площади под кривой роста для репрезентативной выборки микробиоты человека, включившей 38 бактерий-комменсалов (в т.ч. бифидо- и лактобактерий) и значения минимальных ингибирующих концентраций (MIC) для 152 штаммов болезнетворных бактерий. Показано, что орнитин в меньшей степени, чем молекулы сравнения, стимулирует рост патогенных бактерий родов Aspergillus, Klebsiella, Pseudomonas, Staphylococcus и грибов Candida. Орнитин также в меньшей степени стимулирует рост более агрессивных бактерий (уровень биобезопасности 2) и в большей степени — менее агрессивных бактерий (уровень биобезопасности 1). Стимулируя микроорганизмы-продуценты масляной и других короткоцепочечных жирных кислот, орнитин может улучшать профиль микробиоты кишечника.</p></abstract><trans-abstract xml:lang="en"><p>Hepatoprotectors and prebiotic molecules that promote the growth of intestinal flora differ significantly in their effects on different representatives of the human microbiome. This work presents the results of a comparative chemomicrobiomic analysis of ornithine and reference molecules (S-ademetionine, ursodeoxycholic acid, lactulose, and fructose). For each of the studied molecules, estimates of the values of the area under the growth curve were obtained for a representative sample of human microbiota, which included 38 commensal bacteria (including bifidobacteria and lactobacilli) and the values of the minimum inhibitory concentrations (MIC) for 152 strains of pathogenic bacteria. It has been shown that ornithine, to a lesser extent than the reference molecules, stimulates the growth of pathogenic bacteria of the genera Aspergillus, Klebsiella, Pseudomonas, Staphylococcus and Candida fungi. Ornithine is also less likely to stimulate the growth of more aggressive bacteria (Biosafety Level 2) and to a greater extent less aggressive bacteria (Biosafety Level 1). By stimulating butyric and other short-chain fatty acid-producing microorganisms, ornithine can improve the profile of gut microbiota.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гепатопротекторы</kwd><kwd>пребиотики</kwd><kwd>микробиота человека</kwd><kwd>хемоинформатика</kwd><kwd>интеллектуальный анализ данных</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatoprotectors</kwd><kwd>prebiotics</kwd><kwd>human microbiota</kwd><kwd>chemoinformatics</kwd><kwd>data mining</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">Громова О.
