“…That theory was proven by the preceding study [57] showing that the lower the crystallinity of cellulose powder, the higher was the moisture sorption. Herein, control BC was the most amorphous sample and with the best ability to absorb water (97%) with the crystallinity index of 62%, which is similar to previously reported studies [58,59]. Swelling capacities of the BC-DHP composites were predicted from the calculated degree of crystallinity.…”

Lignins and lignin-derived compounds are known to have antibacterial properties. The wound healing agents in the form of dressings produce faster skin repair and decrease pain in patients. In order to create an efficient antimicrobial agent in the form of dressing in the treatment of chronic wounds, a composite hydrogel of bacterial cellulose (BC) and dehydrogenative polymer of coniferyl alcohol (DHP), BC-DHP, was designed. Novel composite showed inhibitory or bactericidal effects against selected pathogenic bacteria, including clinically isolated ones. The highest release rate of DHP was in the first hour, while after 24 h there was still slow release of small amounts of DHP from BC-DHP during 72 h monitoring. High-performance liquid chromatography coupled with mass-spectrometry showed that BC-DHP releases DHP oligomers, which are proposed to be antimicrobially active DHP fractions. Scanning electron microscopy and atomic force microscopy micrographs proved a dose-dependent interaction of DHP with BC, which resulted in a decrease of the pore number and size in the cellulose membrane. The Fourier-transform infrared absorption spectra of the BC-DHP showed that DHP was partly bound to the BC matrix. The swelling and crystallinity degree were dose-dependent. All obtained results confirmed BC-DHP composite as a promising hydrogel for wounds healing.

“…The FT-IR spectra of BC membrane obtained from G.hansenii ATCC 23769 was detected at wave numbers ranging from 500 to 4000 cm -1 as can be seen in Fig.5. The band of intense absorption in the BC spectrum at 3345.2 cm -1 was attributed to the presence of hydroxyl group (OH) of cellulose type I and is important for elucidating hydrogen-bonding patterns which are in agreement with some literatures [41,43,47], strong absorption band at 2896.8 cm -1 was also attributed to the presence of stretching of CH this are in agreement with other studies [41,44,47]. The cellulose absorption spectrum is the band at 1638 cm −1 which has been assigned to carboxyl functional group (C=O) [47].…”

I N THIS STUDY, an optimization of the culture parameters used for the production of bacterial cellulose (BC) by G.hansenii ATCC 23769 was carried out. This is the first study reported statistical optimization of the fermentation medium by Plackett-Burman Design (PBD) and Box-Behnken Designs (BBD) for BC production by type strain G.hansenii ATCC 23769. The effect of seven culture parameters on BC production was evaluated by implementing PBD, where the results revealed that, the most significant variables affecting BC production were yeast extract, temperature and incubation time. Response surface methodology (RSM) using BBD was applied to find out the optimum level of each significant variable. The optimal levels of the three significant components were found to be yeast extract 13 g/l, temperature 26.3°C and incubation time 12 days with a predicted yield 2.91 g/l. According to the results of the PBD and BBD the following medium composition is expected to be optimum (g/l): mannitol 25, yeast extract 13, ethanol 7 ml/l, pH 7, inoclume size 7%, temperature 26.3°C and incubation time 12 days. Characterization of dried BC membrane was carried out to determine the morphological structure and purity by Scanning Electron Microscopy (SEM), crystallinity by X-ray Diffraction (XRD), chemical structure and functional group by Fourier-Transform Infrared spectroscopy (FT-IR), and thermal stability by Thermogravimetric Analysis (TGA). In addition, mechanical properties such as: the Young's modulus, tensile strength, elongation at beak % and thickness of BC membrane obtained from G.hansenii ATCC 23769 were determined.

“…Recently, it has been reported that BC can be synthesized under alkaline environment. 44 A bacterial strain isolated from fermented fruit juice, Komagataeibacter intermedius FST213-1, can produce BC within pH 4–9 and exhibit maximum BC production (1.2 g/L) at pH 8 in short-term (4-day) cultivation. 44 …”

To reduce the cost of obtaining bacterial cellulose, acidic by-products of the alcohol and dairy industries were used without any pretreatment or addition of other nitrogen sources. Studies have shown that the greatest accumulation of bacterial cellulose (6.19g/L) occurs on wheat thin stillage for 3 days of cultivation under dynamic conditions, which is almost 3 times higher than on standard Hestrin and Schramm medium (2.14g/L). The use of whey as a nutrient medium makes it possible to obtain 5.45g/L bacterial cellulose under similar conditions of cultivation. It is established that the pH of the medium during the growth of Gluconacetobacter sucrofermentans B-11267 depends on the feedstock used and its initial value. By culturing the bacterium on thin stillage and whey, there is a decrease in the acidity of the waste. It is shown that the infrared spectra of bacterial cellulose obtained in a variety of environments have a similar character, but we found differences in the micromorphology and crystallinity of the resulting biopolymer.
