“…The in situ PVA/BC nanocomposites developed so far present a highly porous, percolated morphology; their chemical, mechanical, and thermal properties make them appropriate as biomaterials [20,26,[28][29][30][31]. Any biomedical application, however, demands in vitro assessments, which are available for BC biomaterials for wound dressings [32][33][34][35]; however, to the best of our knowledge, no reports exist in this context for PVA/BC nanocomposites obtained via in situ fermentation.…”

“…Fibroblasts, being present in great amounts on the skin, were chosen to conduct the test. They are responsible for skin cell regeneration and are used for testing biomaterials for skin substitutes [11,33,41,42]. To monitor cell adhesion, the biomaterials were stained with haematoxylin-eosin and imaged with a Leica microscope and micrometrics camera.…”

We investigated wound dressing composites comprising fibrils of bacterial cellulose (BC) grown by fermentation in the presence of polyvinyl alcohol (PVA) followed by physical crosslinking. The reference biointerface, neat BC, favoured adhesion of fibroblasts owing to size exclusion effects. Furthermore, it resisted migration across the biomaterial. Such effects were minimized in the case of PVA/BC membranes. Therefore, the latter are suggested in cases where cell adhesion is to be avoided, for instance, in the design of interactive wound dressings with facile exudate control. The bioactivity and other properties of the membranes were related to their morphology and structure and considered those of collagen fibres. Bioactive materials were produced by simple 3D templating of BC during growth and proposed for burn and skin ulcer treatment.

“…The maximum peak at wavelength of 225.80 nm in the spectrum of colloidal silver nanoparticles showed that there is still a AgNO 3 compound, it is possible because of the interaction between Ag with H + as a reaction product formed AgNO 3 solution. A maximum peak at wavelength of 423.40 nm indicated the presence of silver nanoparticles (Lina et al, 2011 andBrugnerotto et al, 2001). Based on Particle Size Analyzer results indicated that the reduction of silver nitrate solution with a reducing agent of trisodium citrate has a median particle size of 74.8 nm and modus of 61.8 nm.…”

“…The smaller the particle size, the greater the antimicrobial effect is generated. (Fang et al, 2005;Lina et al, 2011;Kuusipalo et al, 2005;and Anicuta et al, 2010). Silver nanoparticles are generally smaller than 100 nm and containing silver as much 20 -15000 atom (Brugnerotto et al, 2001).…”

Bacterial cellulose (C) and its composites were synthesized from rice waste water with addition of glycerol (G) and chitosan (Ch). Antibacterial activity of the C, the bacterial cellulose-chitosan composite (CCh), and the bacterial cellulose -glycerolchitosan composite (CGCh) which were deposited silver nanoparticles against S. aureus, E. coli, and yeast C. albicans has been conducted. Silver nanoparticles was prepared by chemical reduction of a silver nitrate solution, a trisodium citrate as a reductor, and a PVA as a stabilizer. The UV-Vis spectroscopy is used to determine the formation of silver nanoparticles. The characterization was conducted on the bacterial celluloses and those composites including the functional groups by the FTIR, the mechanical properties by Tensile Tester, photos surfaces by SEM, and the test of the antibacterial activity against S. aureus, E. coli, and C. albicans by diffusion method. The silver nanoparticle characterization indicates that the silver nanoparticles are formed at a wavelength of 418.80 nm. The antibacterial test showed an inhibitory effect of the C, the CCh, and the CGCh which are deposited the silver nanoparticles against of S. aureus, E. coli, and C.albicans. The CGChs which are deposited silver nanoparticles has the highest antimicrobial activity against the Staphylococcus aureus ATCC 25923. The CGs which are deposited silver nanoparticles provide the highest antimicrobial activity against the E. coli ATCC 25922 and the yeast Candida albicans ATCC 10231.

“…One method to be preferable to stabilize the specimen prior to significant its wet weight is drying under vacuum (10 mm H2O or 98 Pa). [14,15] This uncomplicated approach lowered the standard deviation on the measurements by about 50% as compared to other manners. Corresponding to dielectric spectroscopy and electron microscopy (EM), there is tightly bound between the water molecules and bacterial cellulose; therefore, BC gels behaves like free bulk water.…”

Abstract:Bacterial cellulose (BC) is produced by some kind of acetic acid bacteria. BC demonstrates unique properties, including upward mechanical strength, superior crystallinity, high-water holding and elevated porosity, which make it every useful biomaterial in many different progressive processes. Nowadays, several research areas in industrial zones are concentrating to fabricate some applicable product from this biomaterial. However, dimension (size and shape) of BC makes a challenge and must be controllable and invariability in repetition experiments. Therefore, in this study, we present one method identify of BC time growth. We investigated the time duration and air rate factors on our bacterial cellulose samples while other conditions are kept changeless. The outcomes show, producing bacteria cellulose can be independent of the time, whilst the air is remained constant. This approach makes several advantages such as interchangeable samples, invariability BC thickness and cost variables in recapitulation investigations.
