“…Several nonpathogenic bacteria are able to produce BC, however, Komagataeibacter medellinensis (former Acetobacter xylinum ) is known as the most efficient producer . On its own, the biosynthesis of cellulose can serve several purposes to the bacterium, from physiological, mechanical and chemical stability protection, to the improvement of interactions and nutrient diffusion .…”

“…BC exhibits superior properties that make it suitable for use in biomedical applications, namely its higher purity, the ultrafine network structure, higher crystallinity, and improved mechanical properties, which arise from the nanofibrils 3D network . The resultant nanofibers have a high surface area, which altogether with the hydrophilic nature of BC, resulting in a high water holding ability and adhesion .…”

Bacterial cellulose (BC) is a nanocellulose form produced by some nonpathogenic bacteria. BC presents unique physical, chemical, and biological properties that make it a very versatile material and has found application in several fields, namely in food industry, cosmetics, and biomedicine. This review overviews the latest state‐of‐the‐art usage of BC on three important areas of the biomedical field, namely delivery systems, wound dressing and healing materials, and tissue engineering for regenerative medicine. BC will be reviewed as a promising biopolymer for the design and development of innovative materials for the mentioned applications. Overall, BC is shown to be an effective and versatile carrier for delivery systems, a safe and multicustomizable patch or graft for wound dressing and healing applications, and a material that can be further tuned to better adjust for each tissue engineering application, by using different methods.

“…They are also known to cause the formation of sulfate ester groups at the surface of nanometric cellulose . Production of bacterial nanocellulose is becoming increasingly popular, but at the same time is still costly and problematic . Hence, the bioconversion of cellulose with enzymes could be a worth considering alternative.…”

Several fungal and bacterial strains are known to be able to degrade polymeric chains of cellulose. In this research, two polymorphic forms of celluloses, Cellulose I (C I) and Cellulose II (C II), were incubated with Ochrobactrum anthropi strain producing the cellulolytic enzymes. In the result, nanocrystalline celluloses with distinctive particle sizes distributions, as well as intact supermolecular and chemical structures were produced. The differences in yield of nanometric particles of each polymorphic form were discussed in accordance to crystallographic form of cellulose. Solvent casting method was applied to produce chitosan films filled with 1, 3, and 5 wt% of nanocrystalline C I and nanocrystalline C II. Mechanical testing proved that the tensile properties of the composites were closely related to the polymorphic variety of nanocrystalline cellulose. On the other hand, SEM microphotographs of the produced composites confirmed that good distribution of nanoparticles in the chitosan matrix was crucial for obtaining materials with enhanced mechanical properties. Filling the chitosan matrix with 1 wt% of nanocrystalline C I was determined to be the most effective. POLYM. COMPOS., 39:E448–E456, 2018. © 2017 Society of Plastics Engineers

“…Cellulose produced by bacteria is a promising material for many applications, for example, it can be used for edible packing in the food industry, as wound dressing materials, artificial skin, and scaffolds in regenerative medicine, as electrically conductive paper, and as organic-inorganic hybrid for visible light transmission among others (Shah et al, 2013;Campano et al, 2016). Broad range of the above applications is determined by the particular properties of the BC, which does not have lignin and hemicellulose in comparison to the cellulose derived from plants.…”

Abstract:Need for large quantity of bacterial cellulose (BC), used as a matrix for production of numerous materials with desirable properties, has increased in the fields of biomedicine and electronics. To achieve the goals further investigations are essential in order to understand the intracellular polymerisation reaction; to increase the biosynthesis rate and reduce cost of the overall production process. Carbon sources for the BC production are usually glucose, fructose, and sucrose, so juices from low grade fruits can successfully substitute the carbohydrates, vitamins, ascorbic acid, and proteins in the growth medium and can form low-cost substrates. We used strain Gluconoacetobacter xylinus CICC10529 to produce cellulose from watermelon and mandarin juices (70% v/v and 80% v/v) with or without yeast extract supplement. The liquid media (with working volumes 50 mL and 100 mL) made from fruit juices always contained MgSO 4 .7H 2 O (1.5 w/v%), K 2 HPO 4 (0.1 w/v%), as well as ethanol (1 v/v%). Two modes of operation: static biosynthesis in incubator and dynamic biosynthesis in orbital shaker (at 200 rpm) were conducted at 30°C. The production process was monitored during 7 to 10 days. Thermal properties of BC produced at different conditions were investigated through thermal gravimetric analysis and width of the cellulose fibrils/ribbons were compared via microscopic observations.
