Production and Studying Properties of Composites Based on Bacterial Cellulose and Poly-N, N-Dimethyl-3,4-Methylenpirrolidine Chloride

Bacterial Cellulose (BC) and BC Composites: Production and Properties

“…Still, more noticeable decomposition, with the samples losing 70-80% of their weight, was observed at 360-390 °C. It is consistent with the data reported by other authors [79], showing the In addition to the intensity of these bands, their displacement is also essential. The spectral region 1162 cm −1 corresponds to cellulose C-O-C bridges.…”

“…onset = 220 • C) [57]. A study by Mohammadkazemi et al [63] showed that the start of thermal decomposition of BC could occur between 200 and 250 • C. Still, more noticeable decomposition, with the samples losing 70-80% of their weight, was observed at 360-390 • C. It is consistent with the data reported by other authors [79], showing the weight loss of the BC sample during thermal decomposition at 300 • C and higher rates of this process at 350-370 • C.…”

“…The inhibition of S. aureus, E. coli, B. coagulans, and Aspergillus niger with BC loaded with amoxiclav and fluconazole was demonstrated [100]. BC/poly-N,N-dimethyl-3,4-methylene pyrrolidinium chloride composites with embedded selenium and hydroxyapatite nanocomplexes exhibited antibacterial properties, inhibiting the growth of E. coli [79]. Positive examples of BC inhibition by antibiotics of wound infection of representatives of Staphylococcus aureus and Bacillus subtilis are described [101].…”

“…In this case, the BC yield was 12.6 g/L, and the productivity was 1.8 g/L•day −1 . In a culture of Gluconacetobacter sucrofermentans B-11267 on a molasses-containing medium with ascorbic acid as an antioxidant, the BC yield reached 2.48 ± 0.12 g/L under static condition and 3.73 ± 0.18 g/L under the dynamic condition in three days of cultivation [79]. The use of enzymatic hydrolysates of miscanthus for growing a symbiotic culture of Medusomyces gisevii Sa-12 increased the yield of BC by 20%.…”

“…On the contrary, the elasticity of BC composites with antimicrobials was (elongation at break, %) in general in all samples higher than in BC/AgNPs composites and the original BC. Information on the preparation and use of composites of BC with antibiotics is less representative [79,93,[100][101][102].…”
