По химической природе ПАВ Acinetobacter calcoaceticus IМВ В-7241, Rhodococcus erythropolis IМВ Ас-5017 и Nocardia vaccinii ІМВ В-7405 являются комплексом нейтральных, глико-, фосфо- и аминолипидов. Согласно данным литературы, аминолипиды характеризуются наиболее высокой антимикробной активностью. Ключевым ферментом биосинтеза аминолипидов у штаммов IМВ В-7241, ІМВ В-7405 и ІМВ Ас-5017 является НАДФ+-зависимая глутаматдегидрогеназа. Предполагается, что выявление возможных активаторов и/или ингибиторов этого фермента с последующей соответствующей модификацией состава питательной среды позволит регулировать состав комплекса ПАВ и его свойства.</p><p>Целью работы было исследование влияния одно- и двухвалентных катионов на активность НАДФ+-зависимой глутаматдегидрогеназы у A. calcoaceticus IМВ В-7241, R. erythropolis IМВ Ас-5017 и N. vaccinii ІМВ В-7405.</p><p>Культивирование штаммов IМВ В-7241, ІМВ Ас-5017 и ІМВ В-7405 осуществляли в жидкой минеральной среде, содержащей этанол и глицерин в качестве источника углерода. Активность НАДФ+-зависимой глутаматдегидрогеназы (КФ 1.4.1.4) в бесклеточном экстракте анализировали по образованию глутамата в процессе окислении НАДФН при 340 нм.</p><p>Установлено, что активаторами НАДФ+-зависимой глутаматдегидрогеназы у A. calcoaceticus ІМВ В-7241 являются катионы кальция (5 мМ), магния (10 мМ) и цинка (0,001–0,01 мМ), у R. erythropolis ІМВ Ас-5017 − катионы кальция (5 мМ), у N. vacсinii IМВ В-7405 − катионы кальция (5 и 10 мМ), натрия (25–100 мМ) и калия (50 и 100 мМ). Дополнительное внесение активаторов фермента или увеличение их содержания в среде культивирования исследуемых штаммов сопровождалось повышением активности НАДФ+-зависимой глутаматдегидрогеназы в 1,5–3 раза по сравнению с таковой на базовой среде.</p><p>Полученные данные предполагают возможность регуляции свойств микробных ПАВ в процессе культивирования продуцента, что в перспективе позволит получать препараты со стабильными заданными свойствами в зависимости от сферы их практического применения. </p></abstract><trans-abstract xml:lang="en"><p>Surfactants of microbial origin are widely used in different industries. The application of microbial surfactants is promising in biology and medicine as an alternative to synthetic disinfectants or drugs due to their antimicrobial and antiadhesive properties. The key enzyme biosynthesis of surface active aminolipids (effective antimicrobials preperations) in Acinetobacter calcoaceticus IMV B-7241, Rhodococcus erythropolis IMV Ac-5017 and Nocardia vaccinii IMV B-7405 is NADP+-dependent glutamate dehydrogenase.</p><p>Aim – to study the effect of mono- and divalent cations on the activity of NADP+-dependent glutamate dehydrogenase in Acinetobacter calcoaceticus IMV B-7241, Rhodococcus erythropolis IMV Ac-5017and Nocardia vaccinii IMV B-7405.</p><p>The activity of NADP+ -dependent glutamate dehydrogenase (EC 1.4.1.4) in the cell-free extract was analyzed for the formation of glutamate in the oxidation of NADPH at 340 nm.</p><p>It was found that activators of this enzyme in A. calcoaceticus ІMV B-7241 were calcium cations (5 mM), magnesium (10 mM) and zinc (0.001–0.01mM), R. erythropolis ІMV Ac-5017 − calcium (5 mM), N. vaccinii IMV B-7405 − calcium (5 and 10 mM), sodium (25−100 mM), potassium (50 and 100 mM). Additional introduction or increase the content of enzyme activators in cultivation medium of studied strains was accompanied by increasing activity of NADP+-dependent glutamate dehydrogenase in 1.5-3 times compared with that in the base medium.</p><p>The possibility of regulating biological properties of final product during cultivation of surfactants producer are discussed. The obtained results suppose modification of microbial surfactants characteristics with the change in cultivation medium of cations content − activators and/or inhibitors of key enzymes biosynthesis of component surfactants responsible for specific biological properties. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Acinetobacter calcoaceticus ІМВ В-7241</kwd><kwd>Rhodococcus erythropolis ІМВ Ас-5017</kwd><kwd>Nocardia vacсinii IМВ В-7405</kwd><kwd>поверхностно-активные вещества</kwd><kwd>активаторы НАДФ+-зависимой глутаматдегидрогеназы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Acinetobacter calcoaceticus IMV B-7241</kwd><kwd>Rhodococcus erythropolis IMV Ac-5017</kwd><kwd>Nocardia vaccinii IMV B-7405</kwd><kwd>surfactants</kwd><kwd>activators of NADP+-dependent glutamate dehydrogenase</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">Biosurfactants: multifunctional biomolecules of the 21st century / D.
