Изучить внутривидовое разнообразие колиформных бактерий, представленных в микробных сообществах биопленок свиных навозных стоков (НС) и оценить влияние химических реагентов на состав микробных консорциумов и некоторые свойства бактерий рода Escherichia.Материал и методы. Биопленки НС получали в лабораторных условиях, изучали их качественный и количественный микробный состав. Для обработки НС применяли растворы H2SO4 и NaOCl. Состав микробиоты определяли методом посева на питательные среды.Результаты. Преобладающими группами микроорганизмов в биопленках НС были облигатно-и факультативно-анаэробные бактерии родов Clostridium, Bacteroides и Escherichia. Род Escherichia представлен E. coli, E. fergusonii, E. hermannii (Atlantibacter hermannii), E. blattae (Shimwellia blattae), E. coli inactive, E. vulneris с различной биохимической активностью. Повышенным колонизационным потенциалом, способствующим выживаемости популяций бактерий в микробном консорциуме, обладают Escherichia fergusonii, Escherichia coli inactive, Escherichia vulneris. Бактерии рода Escherichia способны образовывать ассоциации с факультативным анаэробом Proteus vulgaris и дрожжами Rhodotorula glutinis. Выявлена значительная устойчивость E. сoli к воздействию химических реагентов, используемых для обезврежи- вания и устранения запаха НС (H2SO4 до рН 5,5±0,1; внесение 12,5 мг/л активного хлора в составе NaOCl). Обработка НС не привела к полной гибели E. сoli, однако снизило концентрацию на 2 порядка. Использование указанных химических препаратов позволяет снизить общий объем выделяющихся газов на 30–40% и уменьшить интенсивность неприятного запаха.Заключение. Полученные результаты могут найти практическое применение при разработке составов биопрепаратов для снижения запаха и повышения эффективности рациональной утилизации побочных продуктов животноводства.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To study the intraspecific diversity of coliform bacteria represented in microbial communities in biofilms of manure effluents (ME), as well as to evaluate the effect of chemical reagents on the composition of microbial consortia and some properties of bacteria of the genus Escherichia.Material and Methods. Biofilms of ME were obtained under laboratory conditions and their qualitative and quantitative microbial composition studied. H2SO4 and NaOCl solutions were used for entry into ME. The composition of the microbiota was determined by the method of inoculation on nutrient media.Results. The dominant groups of microorganisms in biofilms of ME were obligate and facultative anaerobic bacteria of the genera Clostridium, Bacteroides and Escherichia. The genus Escherichia is represented by E. coli, E. fergusonii, E. hermannii (Atlantibacter hermannii), E. blattae (Shimwellia blattae), E. coli inactive and E. vulneris with varying biochemical activity. Escherichia fergusonii, Escherichia coli inactive and Escherichia vulneris have increased colonization potential, which contributes to the survival of bacterial populations in the bacterial consortium. Bacteria of the genus Escherichia are able to form associations with the facultative anaerobe Proteus vulgaris and the yeast Rhodotorula glutinis. The significant resistance of E. coli to the effects of chemical reagents used to neutralize and eliminate the smell of ME (H2SO4 to pH 5.5±0.1; introduction of 12.5 mg/l of active chlorine in NaOCl) was revealed. ME treatment did not lead to the complete death of E. coli. However, it reduced the concentration by 2 orders of magnitude. The use of these chemicals can reduce the total volume of gases released by 30–40% and reduce the intensity of unpleasant u.Conclusions. The results obtained can find practical application in the development of formulations of biological products to reduce odour and improve the efficiency of rational disposal of animal by-products.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Побочные продукты животноводства</kwd><kwd>биопленки</kwd><kwd>колиформные бактерии</kwd><kwd>Escherichia</kwd><kwd>консортивные связи микроорганизмов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>By-products of animal husbandry</kwd><kwd>biofilms</kwd><kwd>coliform bacteria</kwd><kwd>Escherichia</kwd><kwd>consort bonds of microorganisms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ИБ ФИЦ Коми НЦ УрО РАН по теме: «Структура и состояние компонентов техногенных экосистем подзоны южной тайги», номер государственной регистрации в ЕГИСУ № 1220401000325.</funding-statement><funding-statement xml:lang="en">The study was supported by the framework of the state task of the Institute of Biology, Federal Research Centre, Komi Scientific Centre, Ural Branch, Russian Academy of Sciences on the topic: «Structure and State of the Components of Technogenic Ecosystems in the Southern Taiga Subzone», state registration number EGISU N 1220401000325.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Данилова Н.В., Галицкая П.Ю., Селивановская С.Ю.
