Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania modyfikowanej celulozy bakteryjnej, według wynalazku, polega na przygotowaniu inokulum poprzez zaszczepienie na podłożu płynnym Herstin - Schramm zawierającym glukozę, ekstrakt drożdżowy, pepton bakteryjny, kwas cytrynowy, Na2HPO4, MgSO4 • H2O, bakterii fermentacji octowej z rodzaju Komagataeibacter, korzystnie szczepem bakterii Komagataeibacter xylinus (dawniej Gluconacetobacter xylinus). Następnie wymieszaniu przez 15 minut i inkubowaniu przez 7 dni w temperaturze 28 - 30°C, ponownym wymieszaniu przez 5 minut, i przeniesieniu tak otrzymanego inokulum w ilości 5 - 20% objętościowych do podłoża produkcyjnego. Istota rozwiązania polega na tym, że hodowlę produkcyjną prowadzi się w podłożu opartym na glukozie i jej pochodnych z dodatkiem 1 - 2% (v/v) oleju roślinnego. Proces produkcyjny prowadzi się w warunkach stacjonarnych przy pH w zakresie 4,5 - 6,0, w temperaturze 25 - 30°C przez okres 4 - 20 dni.The subject of the application is a method for the production of modified bacterial cellulose, according to the invention, consists in the preparation of an inoculum by inoculation on the Herstin-Schramm liquid medium containing glucose, yeast extract, bacterial peptone, citric acid, Na2HPO4, MgSO4 • H2O, acetic fermentation bacteria of the Komagataeibacter genus, preferably a strain of Komagataeibacter xylinus (formerly Gluconacetobacter xylinus). Then mixing for 15 minutes and incubating for 7 days at 28-30 ° C, re-mixing for 5 minutes, and transferring the inoculum thus obtained at 5-20% by volume to the production medium. The essence of the solution lies in the fact that the production culture is carried out in a medium based on glucose and its derivatives with the addition of 1 - 2% (v / v) of vegetable oil. The production process is carried out in stationary conditions at a pH in the range of 4.5 - 6.0, at a temperature of 25 - 30 ° C for a period of 4 - 20 days.
