“…Interestingly, acetic acid was shown to be beneficial for BC production within certain concentration [7]. Thus, if acetic acid could stimulate the xylose utilization, it is possible that lignocellulosic acid hydrolysates could be used as one promising substrate for BC production.…”

“…On the other hand, as reported by Toda et al 24 , in cultures where glucose is the primary carbon source, high concentration of gluconic acid can be another crucial factor responsible for the decreased synthesis of BC. The increased concentration of gluconic acid results in a decreased pH of the medium, which in turn reduces intracellular pH.…”

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 fi rst 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 fi brils, 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 effi ciency of the cellulose synthesis process.

“…These cultures were also characterized by the highest rate of glucose consumption. The synthesis of gluconic acid in bacteria is conducted by membrane-bound glucose dehydrogenase (GDH) 28 . As reported by Zheng et al 36 the magnetic fi eld of a specifi c frequency can increase the activity of this enzyme.…”

The aim of the present study was to evaluate the impact of a rotating magnetic fi eld (RMF) on cellular and biochemical properties of Gluconacetobacter xylinus during the process of cellulose synthesis by these bacteria. The application of the RMF during bacterial cellulose (BC) production intensifi ed the biochemical processes in G. xylinus as compared to the RMF-unexposed cultures. Moreover, the RMF had a positive impact on the growth of cellulose-producing bacteria. Furthermore, the application of RMF did not increase the number of mutants unable to produce cellulose. In terms of BC production effi cacy, the most favorable properties were found in the setting where RMF generator was switched off for the fi rst 72 h of cultivation and switched on for the further 72 h. The results obtained can be used in subsequent studies concerning the optimization of BC production using different types of magnetic fi elds including RMF, especially.
