Summary: A genetically engineered Family 3 Carbohydrate-Binding Module (CBM3) was used to modify bacterial cellulose (BC), resulting in improved wet strength and mechanical properties of BC films. The CBM3-BC films showed excellent performance in various environments and had potential applications in food packaging, paper straw, battery separator, and other fields. Furthermore, the in situ modification strategy used in this study could be applied to functional modifications of other BC materials.

Summary: This study synthesized bacterial cellulose/gum Arabic composite (BC/GA) through in-situ modification using lavender residue hydrolysate for the first time. Adding gum Arabic during in-situ modification significantly increased the yield and production per sugars consumption of BC/GA. The combination of BC and GA was identified as the main mechanism for the beneficial effect of in-situ modification.

Summary: This study focused on the modification of Parylene-C surfaces with selenium nanoparticles as antibacterial agents and tested the designed surfaces against bacterial pathogens and mesenchymal stem cells. The results showed a bacteriostatic effect on E. coli but no antibacterial effect on S. aureus, as well as cytotoxic effects on cells at high nanoparticle deposition. These findings provide valuable information for potential antibacterial treatment of Parylene-C in biomedicine.

Summary: Chemical modification of bacterial cellulose through carboxymethylation was conducted to prepare a low-cost highly stable lead adsorbent material. The study revealed a strong linear correlation between the carboxymethylation extent conferred to BC and the lead retention ability of the obtained CMBC products, emphasizing the key role of negatively charged carboxylate groups in the lead adsorption process. Proper tuning of the carboxymethylation extent allowed maximizing the lead adsorption capacity, doubling the previously reported values.

Summary: This study investigated the effect of acetylated bacterial cellulose (ABC) on its biological performance. Acetylation improved the structural properties of ABC, resulting in enhanced fiber arrangement, optical transparency, hydrophobicity, mechanical strength, and thermal stability. The ABC scaffolds showed improved cell adhesion and proliferation, 3D cell growth pattern, hemocompatibility, and protein adsorption, indicating their potential use in tissue engineering and regenerative medicines.

Summary: In order to achieve the automated fabrication of complex tissue mimicking constructs through 3D bioprinting, it is necessary to develop bioinks that are not only printable and biocompatible but also have integrated cell-instructive properties. Here, we present a scalable technique for generating nanofiber 3D printing inks with unique tissue-guiding capabilities. By tailoring the size and dispersibility of cellulose fibrils, we are able to create nanofibers that match the size and dimensions of natural collagen fibers, allowing for the orientation of cells and the spatial organization of engineered tissues during printing.

Summary: In situ modification of bacterial cellulose (BC) by adding agar and chitosan to the culture media leads to structural and morphological tuning, affecting water absorption/retention and rheological behavior. Agar-modified BC shows reduced pore volume and denser network with lower water absorption, while Chitosan-BC exhibits lower pore volume and reduced swellability with lower water retention. The viscoelastic deformation mechanism and water absorption behavior are discussed with respect to pore shape-size distribution and fiber dimension.

Summary: Biomineralization inspired process to produce polymer of desired need is a promising approach in the field of research. In this study, bacterial cellulose (BC) based nanocomposites were synthesized via a biological route using calcium gluconate as the carbon source, and characterized by SEM and TEM. The uniform distribution of embedded objects on the cellulose nanofibers and the use of organisms for inorganic growth provide new opportunities for designing original nanostructures.
