Abstract
Изобретение относится к области микробиологии и биотехнологии, а именно к штаммам уксуснокислых бактерий, применяемых в медицинской области, в косметологии, в пищевой промышленности и в технической практике. В 1992 году получен штамм Komagataeibacter rhaeticus CALU-1629, синтезирующий наноцеллюлозу в виде целлюлозных гель-пленок, в условиях поверхностного культивирования. В течение последующих 20 лет штамм был отселекционирован на среде простейшего состава, сохранялся в рабочей коллекции путем регулярных периодических пересевов с проверкой целлюлозосинтезирующей активности. Показана стабильность фенотипических и генотипических свойств штамма при его долгосрочном хранении в музейной коллекции кафедры. Штамм характеризуется стабильностью в отношении выхода целевого продукта и способностью использовать дешевые, легко метаболизируемые субстраты типа мелассы. Штамм был депонирован 17 августа 2012 года под регистрационным номером 1629 как Gluconacetobacter xylinus, с последующим уточнением вида путем генотипирования до Komagataeibacter (Gluconacetobacter) rhaeticus. Адрес коллекции: РЦ "Культивирование микроорганизмов" СПб Ботаническая ул., д. 17 лит. А, Ораниенбаумский пр. д.2, корп.6. Техническим результатом заявленного изобретения является высокая целлюлозосинтезирующая активность с максимальным выходом бактериальной целлюлозы по сухому весу 8,0-8,5 г/л. Штамм пригоден для получения целлюлозных гель-пленок, которые применяются в медицинской практике как раневые покрытия, искусственные сосуды, хрящ, прекурсор кости, а также в области косметологии, технической практике (создание проводящих композитов для солнечных батарей, композиционных покрытий высокой электрической прочности, для производства жидкокристаллических дисплеев, элитных акустических мембран, мембран для разделения органических жидкостей) и в пищевой промышленности.The invention relates to the field of microbiology and biotechnology, namely the strains of acetic acid bacteria used in the medical field, in cosmetology, in the food industry and in technical practice. In 1992, the strain Komagataeibacter rhaeticus CALU-1629 was obtained, which synthesizes nanocellulose in the form of cellulose gel films, under surface culture conditions. Over the next 20 years, the strain was selected on the medium of the simplest composition, was preserved in the working collection by regular periodic transfers with checking cellulose-synthesizing activity. The stability of the phenotypic and genotypic properties of the strain during its long-term storage in the museum collection of the department is shown. The strain is characterized by stability in relation to the yield of the target product and the ability to use cheap, easily metabolized substrates such as molasses. The strain was deposited on August 17, 2012 under registration number 1629 as Gluconacetobacter xylinus, with the subsequent refinement of the species by genotyping to Komagataeibacter (Gluconacetobacter) rhaeticus. Collection address: RC "Cultivation of microorganisms" St. Petersburg Botanicheskaya st., 17 lit. A, Oranienbaum pr. D.2, block 6. The technical result of the claimed invention is a high pulp synthesis activity with a maximum yield of bacterial cellulose on a dry weight of 8.0-8.5 g / l. The strain is suitable for the production of cellulosic gel films, which are used in medical practice as wound coverings, artificial vessels, cartilage, bone precursor, as well as in the field of cosmetology, technical practice (creation of conductive composites for solar cells, composite coatings of high electrical strength, for the production of liquid crystal displays, elite acoustic membranes, membranes for the separation of organic liquids) and in the food industry.
