Установлено, что процесс ультрафильтрации без предварительной обработки культуральной жидкости неэффективен вследствие образования на поверхности мембран гель-слоя из высокомолекулярных (Mw = 2 900 Кд) побочных продуктов биосинтеза. Предложен способ предварительной очистки культуральной жидкости, позволяющий увеличить скорость фильтрации от 8-10 до 20-25 л/м2ч.</p></abstract><trans-abstract xml:lang="en"><p>The polysulfone hollow fiber membranes have been studied for clarification of the Acetobacter culture broth. It has been found that ultrafiltration of the broth without additional pre-treatment is unefficient due to formation the gel-layer of high molecular weight biosynthesis byproduct (Mw = 2900 kD) on the membrane surface. The method for pre-treatment of the culture broth, increasing the average flux from 8-10 up to 20-25 l/m2h, has been proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уксус</kwd><kwd>ультрафильтрация</kwd><kwd>полисульфон</kwd><kwd>полые волокна</kwd><kwd>гель-поляризация</kwd><kwd>vinegar</kwd><kwd>ultrafiltration</kwd><kwd>polysulfone hollow fibers</kwd><kwd>biofilm gel layer</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">Мюллер, Г.
