The high-performance sequencing showed that 99.1 % of the bacterial fraction of the fresh 7-d culture was <em>Proteobacteria </em>of mostly cellulose-producing genera with the order <em>Acetobacterales </em>being dominant and represented by the <em>Komagataeibacter</em> (87.3 %) and <em>Gluconobacter</em> (6.3 %). Aging of the Kombucha bacterial consortium from 20 to 90-d cultivation lead to the reduction of number of cellulose-producing bacteria and intense growth of cellulolytic bacteria including <em>Clostridiales</em>, <em>Bacteroidetes</em>, <em>Actinomyces</em>. Also the acidophilic microorganisms have been detected. The long-term growth of the Kombucha bacterial consortium can be considered as a succession of microbial communities.</p> ER -
