“…Structurally, BC is ribbon-like cellulose nanofibers that further weave into 3D reticulated network ( Figure 4 ; Ruka et al, 2014 ). It is characterized with high purity, high degree of polymerization and high crystallinity (Choi and Shin, 2020 ). BC is free of the symbiotic components in plants such as lignin, hemicellulose, and pectin.…”

Bacterial cellulose (BC) is a natural biomaterial synthesized by bacteria. It possesses a unique structure of cellulose nanofiber-weaved three-dimensional reticulated network that endows it excellent mechanical properties, high water holding capability and outstanding suspension stability. It is also characterized with high purity, high degree of crystallinity, great biocompatibility and biodegradability. Due to these advantages, BC has gained great attentions in both academic and industrial areas. This critical review summarizes the up-to-date development of BC production and application from an industrial perspective. Firstly, a fundamental knowledge of BC's biosynthesis, structure and properties is described, and then recent developments in the industrial fermentation of BC are introduced. Subsequently, the latest commercial applications of BC in the areas of food, personal care, household chemicals, biomedicine, textile, composite resin are summarized. Finally, a brief discussion of future development of BC industry is presented at the end.

“…Many compounds and intermediates such as glycerol, pyruvates, hexoses, and dicarboxylic acids can be converted to cellulose compounds. The most efficient BC producer is Komagataeibacter xylinus (K. xylinus) , known previously as Gluconacetobacter xylinus or Acetobacter xylinus [ 62 ]. It is a Gram-negative aerobic bacterium.…”

“…Briefly, BC is biosynthesized by acetic acid bacteria in a culture medium via oxidative fermentation processes. Under suitable conditions for bacterial growth, glucose becomes the source of carbon, peptones for nitrogen, yeast for vitamins and disodium phosphate and citric acid as the phosphate buffer for the culture medium [ 62 ]. The biosynthesis of BC by K. xylinus involves the process of polymerizing glucose into linear β-(1,4)-glucan chains and has become a model for other NC biosynthesis pathways.…”

Research and development of nanocellulose and nanocellulose-reinforced composite materials have garnered substantial interest in recent years. This is greatly attributed to its unique functionalities and properties, such as being renewable, sustainable, possessing high mechanical strengths, having low weight and cost. This review aims to highlight recent developments in incorporating nanocellulose into rubber matrices as a reinforcing filler material. It encompasses an introduction to natural and synthetic rubbers as a commodity at large and conventional fillers used today in rubber processing, such as carbon black and silica. Subsequently, different types of nanocellulose would be addressed, including its common sources, dimensions, and mechanical properties, followed by recent isolation techniques of nanocellulose from its resource and application in rubber reinforcement. The review also gathers recent studies and qualitative findings on the incorporation of a myriad of nanocellulose variants into various types of rubber matrices with the main goal of enhancing its mechanical integrity and potentially phasing out conventional rubber fillers. The mechanism of reinforcement and mechanical behaviors of these nanocomposites are highlighted. This article concludes with potential industrial applications of nanocellulose-reinforced rubber composites and the way forward with this technology.

“…Recently, BC has attracted significant attention because it can be used to produce a wide range of functional and structural materials (Choi and Shin, 2020 ). It has excellent potential for applications in medicine such as a biomaterial for tissue engineering (Carvalho et al, 2019 ; Hickey and Pelling, 2019 ; Luo et al, 2019 ), wound dressing (Sulaeva et al, 2015 ; Carvalho et al, 2019 ; Portela et al, 2019 ; Teixeira et al, 2020 ), and controlled drug delivery (Carvalho et al, 2019 ).…”

“…Furthermore, BC can be used in dietetics as a carrier of additives for balanced nutrition, in industrial electronics to produce optically transparent compounds with an ultra-low thermal expansion coefficient, and in manufacturing of acoustic diaphragms. It is a promising source for obtaining nanocrystalline cellulose, and biocomposite materials (Sharma et al, 2019 ; Choi and Shin, 2020 ). Currently, it is prevalent in the production of several biocomposites that have antibacterial and hemostatic properties.…”

Aerogels have gained significant interest in recent decades because of their unique properties such as high porosity, low density, high surface area, and excellent heat and noise insulation. However, their high cost and low mechanical strength limit their practical application. We developed appropriate conditions to produce aerogels with controlled density, high mechanical strength, and thermal characteristics from bacterial cellulose (BC) synthesized by the strain Komagataeibacter sucrofermentans H-110. Aerogels produced using TEMPO oxidized BC (OBC) exhibited high mechanical strength and lower shrinkage than those from native bacterial cellulose (NBC). Compared to the NBC, the use of TEMPO-oxidized BC with oxidation degrees (OD) of 1.44 and 3.04% led to the reduction of shrinkage of the aerogels from 41.02 to 17.08%. The strength of the aerogel produced from the TEMPO-oxidized BC with an oxidation degree of 1.44% was twice that of the aerogel produced from NBC. The addition of Mg2+ at concentrations of 20 and 40 mM during the preparation of the aerogels increased the strength of the aerogels by 4.9 times. The combined use of TEMPO-oxidized BC and Mg2+ allowed pore size reduction from 1,375 to 197.4 μm on the outer part of the aerogels, thereby decreasing the thermal conductivity coefficient from 0.036 to 0.0176 W/(m•K). Furthermore, novel biocomposites prepared from the aerogels based on NBC and OBC and sodium fusidate, which have high antibiotic activity against Staphylococcus aureus, were obtained. Owing to their antibacterial properties, these aerogels can be used as functional biomaterials in a wide range of applications such as in tissue engineering and fabrication of wound dressing materials.
