Abstract The aim of the study was to analyze the changes in the parameters of bacterial cultures and bacterial cellulose (BC) synthesized by four reference strains of Gluconacetobacter xylinus during 31-day cultivation in stationary conditions. The study showed that the most visible changes in the analyzed parameters of BC, regardless of the bacterial strain used for their synthesis, were observed in the first 10–14 days of the experiment. It was also revealed, that among parameters showing dependence associated with the particular bacterial strain were the rate and period of BC synthesis, the growth rate of bacteria anchored to the cellulose fibrils, the capacity to absorb water and the water release rate. The results presented in this work may be useful in the selection of optimum culturing conditions and period from the point of view of good efficiency of the cellulose synthesis process.

The production of bacterial cellulose (BC) from Gluconacetobacter xylinus could be improved by the two-stage cultivation strategy. The jar fermentor was applied at first stage to increase cell concentration. At the second stage, the bacteria statically grew within beaker. Three different fraction of cell volumes were cultured in modified YPD-glucose medium or YPD-molasses one. In the modified YPD-molasses medium, the BC yield were highest in this study when the consuming rate of reducing sugars (RS) was 0.181 g-dry BC L-1 d-1 and the BC production rate was 0.183 g-dry BC/g-RS, respectively. The modified YPD-glucose medium could get the maximum pellicle thickness of 5.56±0.64 mm and water content of 99.4%, respectively.
