Исследование влияния антибиотиков разных групп: тилозина, окситетрациклина и бензилпенициллина на потенциальную нитрифицирующую и целлюлозолитическую активности серой лесной почвы методами модельных лабораторных исследований.Материал и методы. Объект исследования - окультуренная серая лесная среднесуглинистая почва. Исследование осуществлялось путем проведения модельных лабораторных экспериментов. Анализируемые образцы инкубировались при 27°C в отсутствие освещения в течение 30 суток, затем определялась целлюлозолитическая активность (аппликационным методом) и нитрифицирующая активность (потенциометрическим методом). Был установлен таксономический состав бактериального сообщества исследуемой почвы на основании анализа ампликонных библиотек фрагментов рибосомальных оперонов методом высокопроизводительного секвенирования генов 16S рРНК.Результаты. Наибольшее число нитрифицирующих организмов исследуемой почвы - археи семейства Nitrososphaeraceae, являющиеся автотрофными окислителями аммония. Наиболее устойчивой к воздействию использованных антибиотиков являлась целлюлозолитическая активность, которая подавлялась только при добавлении тилозина и его смеси с окситетрациклином. Нитрифицирующая активность почвы изменялась в зависимости от состава и концентрации вносимых препаратов, наибольшее ингибирующее воздействие оказал тилозин. Смеси антибиотиков незначительно усиливали процесс нитрификации при 50-100 мг/кг, и подавляли в диапазоне 150-700 мг/кг.Выводы. Попадая в почву, исследуемые антибиотики способны как стимулировать, так и ингибировать ферментативные процессы. Наибольшее воздействие оказывают смеси антибиотиков в сравнении с их индивидуальным внесением. В среднесуглинистой серой лесной почве присутствие антибиотиков более опасно для нитрифицирующей активности.</p></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To investigate the effect of certain antibiotics - tylosin, oxytetracycline and benzylpenicillin - on the potential nitrifying and cellulolytic activity of gray forest soil using laboratory model research methods.Material and Methods. The object of the research was agricultural gray forest medium loamy soil. The study was carried out by conducting laboratory model experiments. The analysed samples were incubated at 27°C and in the absence of illumination for 30 days and then subsequently analysed for cellulolytic activity (by the application method) and nitrification activity (by the potentiometric method). The taxonomic composition of the bacterial community of the studied soil was established based on analysis of amplicon libraries of fragments of ribosomal operons of 16S rRNA genes by the NGS method.Results. The largest number of nitrification organisms in the soil studied were archaea of the family Nitrososphaeraceae which are autotrophic ammonium oxidants. Most resistant to the effects of the antibiotics used was cellulolytic activity which was suppressed only by the addition of tylosin and its admixture with oxytetracycline. The nitrification activity of the soil varied depending on the concentration and preparations applied, the greatest inhibitory effect being exerted by tylosin. Antibiotic mixtures slightly enhanced the nitrification process at 50-100 mg/kg and were suppressed in the range of 150-700 mg/kg. Conclusion. Once in the soil, the antibiotics studied are capable of both stimulating and inhibiting enzymatic processes. Mixtures of antibiotics rather than their individual applications produce the greatest impact. In medium loamy gray forest soil the presence of antibiotics is more dangerous to nitrification activity.</p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>антибиотики</kwd><kwd>целлюлозолитическая активность</kwd><kwd>нитрифицирующая активность</kwd><kwd>серая лесная почва</kwd><kwd>почвенная микробиота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antibiotics</kwd><kwd>cellulolytic activity</kwd><kwd>nitrification activity</kwd><kwd>grey forest soil</kwd><kwd>soil microbiota</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">Grenni P., Ancona V., Caracciolo A.B.
