Определен титр (КОЕ в 1 см3 исходного инокулята) и ингибиторная активность штаммов по отношению к панкреатической α-амилазе в растворах, полученных при культивировании Streptomyces на гидролизате кукурузного крахмала. Установлен высокий (91–100 %) уровень выживаемости Streptomyces после хранения при температурах -80 и -150 °C c применением 15 %-го раствора глицерина в качестве криопротектора. Выявлено, что штамм Streptomyces violaceus наиболее устойчив к условиям длительного хранения при низких температурах. Он полностью сохранил ингибиторную активность после хранения при температурах -80 и -150 °С. Максимальный уровень активности ингибитора панкреатической α-амилазы у штамма Streptomyces violaceus отмечается на 1-е сутки рекультивирования и составляет (2250±200) ИЕ/см3 , у Streptomyces lucensis ВКПМ Ас-1743 – на 3-и сутки рекультивирования и достигает значения 3660±200 ИЕ/см3 после хранения при температуре -80 °С. Исследуемые штаммы Streptomyces являются пигменто-образующими. Наиболее интенсивное пигментообразование отмечено при культивировании штамма Streptomyces violaceus, хранившегося при -150 °С. Проведенные исследования показали, что криоконсервация штаммов актиномицетов Streptomyces violaceus и Streptomyces lucensis при температурах -80 и -150 °С с применением 15 %-го раствора глицерина в качестве криопротектора обеспечивает высокую (107 –108 ) степень выживаемости клеток и сохранение их ингибиторной активности на высоком уровне. Экспериментальные данные свидетельствуют о перспективности метода низкотемпературного хранения для коллекционных культур Streptomyces lucensis и Streptomyces violaceus.</p><p>Авторы заявляют об отсутствии конфликта интересов.</p></abstract><trans-abstract xml:lang="en"><p>The article presents a study into the effect of long-term, low-temperature (-80 and -150 °С) storage on the properties of Streptomyces lucensis RNCIM As-1743 and Streptomyces violaceus RNCIM As-1734 actinomycete collection strains acting as producers of glycosidase inhibitors. The titre (CFU in 1 cm3 of the initial inoculum) and the inhibitory activity of strains were determined with respect to pancr eatic α-amylase in the solutions obtained by Streptomyces culture on a corn starch hydrolysate. For Streptomyces, a high survival rate (91–100 %) was established after storage at temperatures of -80 and -150 °C using a 15 % glycerol solution in terms of a cryoprotector. Streptomyces violaceus strain was identified to be the most resistant to long-term storage at low temperatures. Its inhibitory activity turns to be completely retained after storage at temperatures of -80 and -150 °С. In Streptomyces violaceus strain, the maximum activity level of 2250±200 IU/cm3 for an inhibitor of pancreatic α-amylase is observed on the 1st day of subculture, while Streptomyces lucensis RNCIM As-1743 demonstrates the highest activity value on the 3rd day to reach a value of 3660±200 IU/cm3 following storage at a temperature of -80 °С. The studied Streptomyces strains are chromogenic. The most intense chromogenesis is noted during the culture of Streptomyces violaceus strain stored at a temperature of -150 °С. The cryopreservation of Streptomyces violaceus and Streptomyces lucensis actinomycete strains was established to provide high (107 –108 ) cell survival and preservation of their inhibitory activity at a high level when exposed to temperatures of -80 and -150 °С with a 15 % glycerol solution as a cryoprotector. Experimental data indicate the low-temperature storage method to be promising for Streptomyces lucensis and Streptomyces violaceus collection cultures.</p><p>The authors declare no conflict of interests regarding the publication of this article.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>штаммы Streptomyces lucensis ВКПМ Ас-1743 и Streptomyces violaceus ВКПМ Ас-1734</kwd><kwd>низкотемпературное хранение</kwd><kwd>жизнеспособность</kwd><kwd>ингибиторная активность</kwd><kwd>пигментообразование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Streptomyces lucensis RNCIM As-1743 strains</kwd><kwd>Streptomyces violaceus RNCIM As-1743 strains</kwd><kwd>low-temperature storage</kwd><kwd>viability</kwd><kwd>inhibitory activity</kwd><kwd>chromogenesis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Программы фундаментальных научных исследований государственных академий наук на 2019 г. по проекту № 163.</funding-statement><funding-statement xml:lang="en">The work was supported by the Program of fundamental scientific research for State Academies of Sciences 2019 (project no. 163).</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">Савкина О.А., Терновской Г.В., Локачук М.Н., Павловская Е.Н., Сафронова В.И.
