The influence of microbiological medium composition on the efficiency of bacterial cellulose synthesis

Abstract

The influence of the composition of microbiological medium on the efficiency of bacterial cellulose synthesis. The main objective was to investigate the effect of culture medium composition on the process of bacterial cellulose synthesis. Five different nutrients were used as carbon sources for cellulose synthesising microorganisms: glucose, fructose, erythrol, inulin and lactose, added to the medium at three different concentrations (1%, 2.5%, and 4.5%). It was observed that the type and amount of nutrients included in the culture medium significantly affected the cellulose synthesis efficiency. It was observed that the best results of polymer synthesis were obtained on medium containing 1% fructose. Furthermore, the results obtained clearly confirm that the composition of the culture medium has a significant effect on the water retention of the polymer during its synthesis on the culture media.
