В качестве штаммов-деструкторов были взяты микроорганизмы: Pseudomonas fluorescens TR (ВКПМ В-4881), Pseudomonas putida TП-19 (B-6582), Pseudomonas stutzeri T (B-4904), Pseudomonas putida TШ-18 (B-2950), Pseudomonas putida TO (B-3959), Pseudomonas mendocina 2S (B-4710), Pseudomonas oleovorans TF4-1L (B-8621) и активный ил, полученный с аэротенков действующего предприятия Кузбасса. Биоокисление ПАВ проводили в стеклянных колбах объемом 250 см3, помещенных в шейкер-инкубатор, в условиях постоянной температуры 30 ºС для чистых культур и 18 ºС – для активного ила. Штамм-деструктор должен обладать способностью за минимальный временной интервал снижать концентрацию сурфактанта до безопасных значений. Штаммы Pseudomonas stutzeri T (В-4904) и Pseudomonas fluorescens TR (В-4881) показали наименьший период полураспада сурфактанта – 2,5 и 2,6 суток соответственно. Несколько большие периоды показали штаммы Pseudomonas putida TO (В-3959), Pseudomonas putida TШ-18 (В-2950) и Pseudomonas oleovorans TF4-1L (В-8621) – 3,0; 4,5 и 4,9 суток соответственно. Наибольший период полураспада ПАВ показали микроорганизмы Pseudomonas mendocina 2S (В-4710) – 5,5 суток, и Pseudomonas putida TП-19 (В-6582) – 6,0 суток. Максимальная степень биодеструкции сурфактанта наблюдалась при действии биоценоза микроорганизмов. За 14 суток концентрация кокамидопропилбетаина снизилась до 0,27% от его начальной концентрации. Показана эффективность использования бактерий рода Pseudomonas в качестве деструкторов сурфактантов. Бактерии данного рода имеют короткое время генерации, высокую скорость наращивания биомассы по сравнению с бактериями-деструкторами других родов и меньший период адаптации к ПАВ по сравнению с активным илом. Были подобраны штаммы микроорганизмов Pseudomonas, способных за минимальный временной интервал снижать концентрацию ПАВ до безопасных значений для последующей разработки технологии получения эффективного биопрепарата, предназначенного для очистки сточных вод от амфотерных сурфактантов.</p></abstract><trans-abstract xml:lang="en"><p>Abstract: The paper examines the biodegradation rate of cocamidopropyl betaine by bacteria of the genus Pseudomonas and activated sludge. The following microorganisms were taken as destructor strains: Pseudomonas fluorescens TR (VKPM B-4881), Pseudomonas putida TP-19 (B-6582), Pseudomonas stutzeri T (B-4904), Pseudomonas putida TSh-18 (B-2950), Pseudomonas putida TO (B-3959), Pseudomonas mendocina 2S (B-4710), Pseudomonas oleovorans TF4-1L (B-8621) and activated sludge obtained at activated sludge reactors of a Kuzbass plant. Biooxidation of surfactant samples was carried out in 250 cm3 glass flasks, placed into an incubator shaker, at a constant temperature of 30ºС for pure cultures and 18ºС for activated sludge. The destructor strain should reduce the surfactant concentration to safe values within a minimum time interval. Pseudomonas stutzeri T (B-4904) and Pseudomonas fluorescens TR (B-4881) strains provided the shortest half-life of the surfactant under study – 2.5 and 2.6 days, respectively. For Pseudomonas putida TO (B-3959), Pseudomonas putida TSh-18 (B-2950) and Pseudomonas oleovorans TF4-1L (B-8621) strains, these values amounted to 3.0, 4.5 and 4.9 days, respectively. The maximum half-life of the surfactant under study was demonstrated by Pseudomonas mendocina 2S (B-4710) and Pseudomonas putida TP-19 (B-6582) microorganisms – 5.5 and 6.0 days, respectively. The maximum biodegradation of the surfactant was observed under its exposure to the biocenosis of microorganisms. Over 14 days, the concentration of cocamidopropyl betaine decreased to 0.27% of its initial concentration. The efficiency of Pseudomonas bacteria as destructors of surfactants was demonstrated. Bacteria of this genus exhibit a shorter generation time and a higher rate of biomass growth when compared to other strains and a shorter period of adaptation to surfactants when compared to activated sludge. Capable of reducing surfactant concentrations to safe values in a minimum time interval, Pseudomonas strains can be used as an effective agent in the development of technologies for wastewater purification from amphoteric surfactants.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностно-активные вещества</kwd><kwd>кокамидопропилбетаин</kwd><kwd>бактерии рода Pseudomonas</kwd><kwd>активный ил</kwd><kwd>биодеструкция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surfactants</kwd><kwd>cocamidopropyl betaine</kwd><kwd>Pseudomonas bacteria</kwd><kwd>activated sludge</kwd><kwd>biodegradation</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">Hamouda T., Myc A., Donovan B., Shih A.Y., Reuter J.D., Baker J.R.
