“…Alternatively, agitated cultures, airlift bioreactors, rotating disk bioreactors, stirred tank reactors with a spin filter, biofilm reactors with plastic composite supports, and trickling bed reactors may also be employed in the production of this cellulose type, preventing the conversion of cellulose-producing strains into cellulose-negative mutants [128]. BC can be produced in various forms, depending on the fermentation method; pellicles arise under static culture condition, while fibrils and sphere-like particles emerge under motion conditions [134]. The wastes from several industries (often rich in sugars), e.g., domestic, agricultural, cotton-based textiles, among others, are also gaining significance as carbon sources for BC production, as evidenced in Table 3 [132].…”

“…Its poor solubility in physiological media, as well as the absence of cellulases and beta-glucanases, which increase the stability and functionality of the polymer, has increased the interest of BC as additive or base for potential new biomaterials. To date, BC has been employed in the development of biomaterials for wound dressings, blood vessels, dental implants, scaffolds for tissue engineering of cornea, heart valve, bone and cartilage, and drug delivery applications [134]. Highly crystalline and thermally stable cellulose nanofibrils, with very high aspect ratio, were prepared from AH fibers by HCl hydrolysis followed by mechanical fibrillation.…”

“…Functionalization with 3-aminopropyl triethoxysilane (APS) has been attempted to further enhance cell attachment and antibacterial properties of BC-containing electrospun membranes for wound healing. BC membranes grafted with two organosilanes and acetyled have also shown an improved moisture resistance and hydrophobicity [134]. Naeem et.…”

Wound healing requires careful, directed, and effective therapies to prevent infections and accelerate tissue regeneration. In light of these demands, active biomolecules with antibacterial properties and/or healing capacities have been functionalized onto nanostructured polymeric dressings and their synergistic effect examined. In this work, various antibiotics, nanoparticles, and natural extract-derived products that were used in association with electrospun nanocomposites containing cellulose, cellulose acetate and different types of nanocellulose (cellulose nanocrystals, cellulose nanofibrils, and bacterial cellulose) have been reviewed. Renewable, natural-origin compounds are gaining more relevance each day as potential alternatives to synthetic materials, since the former undesirable footprints in biomedicine, the environment, and the ecosystems are reaching concerning levels. Therefore, cellulose and its derivatives have been the object of numerous biomedical studies, in which their biocompatibility, biodegradability, and, most importantly, sustainability and abundance, have been determinant. A complete overview of the recently produced cellulose-containing nanofibrous meshes for wound healing applications was provided. Moreover, the current challenges that are faced by cellulose acetate- and nanocellulose-containing wound dressing formulations, processed by electrospinning, were also enumerated.

“…Oxidative fermentation of bacteria such as Gluconacetobacter, Sarcina, and Agrobacterium in non-synthetic or synthetic media will form cellulose fibrils with network-like structures that possess high surface area and mechanical properties [ 82 ]. Different bacteria can be used with the manipulation of culture conditions to synthesize BC in different shapes, such as gels and granules [ 83 ]. Surface grafting through the acetylation of BC to nullify the hydrophilicity of BC was able to disperse BC homogeneously in the PLA matrix and improve the stiffness of the nanocomposite while maintaining the tensile strength compared to the neat PLA [ 84 ].…”

Extending Cellulose-Based Polymers Application in Additive Manufacturing Technology: A Review of Recent Approaches

The materials for additive manufacturing (AM) technology have grown substantially over the last few years to fulfill industrial needs. Despite that, the use of bio-based composites for improved mechanical properties and biodegradation is still not fully explored. This limits the universal expansion of AM-fabricated products due to the incompatibility of the products made from petroleum-derived resources. The development of naturally-derived polymers for AM materials is promising with the increasing number of studies in recent years owing to their biodegradation and biocompatibility. Cellulose is the most abundant biopolymer that possesses many favorable properties to be incorporated into AM materials, which have been continuously focused on in recent years. This critical review discusses the development of AM technologies and materials, cellulose-based polymers, cellulose-based three-dimensional (3D) printing filaments, liquid deposition modeling of cellulose, and four-dimensional (4D) printing of cellulose-based materials. Cellulose-based AM material applications and the limitations with future developments are also reviewed.

Over millennia, bacteria have developed clever strategies to build biopolymer‐based communities in which they can survive even extremely challenging conditions. Such bacterial biofilms come with a broad range of fascinating material properties that—in settings such as medicine, food production, or other areas of industry—make it difficult to remove or inactivate them: they can stick to many surfaces, repel water and oils, and can even transport electrons. Inspired by the outstanding versatility and sturdiness of such bacterial biofilms, material scientists have set out to harness those properties and to create bacterial materials for different applications. However, as the range of technological applications employing biofilms keeps expanding, improved material properties or broader functionalities are desired. Here, such attempts where materials with improved properties were created by making use of either natural or modified bacterial biofilms are reviewed. The areas in which those bacterial materials may be used range from agriculture and (environmental) biotechnology over biomedical and electrical engineering to construction engineering.
