“…The more intense reflections in the same areas found for BC–CAR–CS ( Figure 2 (4)) are indicative of stronger intermolecular interactions between the BC fibers due to their reinforcement by the PEC, which can be associated with the presence of stronger acidic -OSO 3 H groups in CAR compared to carboxyl groups in ALG and HA. An increase in the intensity of the reflection at 2θ = 15° for BC–CAR–CS ( Figure 2 (4)) indicates the prevailing orientation of BC nanofibrils along the (−110) crystallographic plane [ 34 ].…”

Bacterial Cellulose (Komagataeibacter rhaeticus) Biocomposites and Their Cytocompatibility

et al. 2020

A series of novel polysaccharide-based biocomposites was obtained by impregnation of bacterial cellulose produced by Komagataeibacter rhaeticus (BC) with the solutions of negatively charged polysaccharides—hyaluronan (HA), sodium alginate (ALG), or κ-carrageenan (CAR)—and subsequently with positively charged chitosan (CS). The penetration of the polysaccharide solutions into the BC network and their interaction to form a polyelectrolyte complex changed the architecture of the BC network. The structure, morphology, and properties of the biocomposites depended on the type of impregnated anionic polysaccharides, and those polysaccharides in turn determined the nature of the interaction with CS. The porosity and swelling of the composites increased in the order: BC–ALG–CS > BC–HA–CS > BC–CAR–CS. The composites show higher biocompatibility with mesenchymal stem cells than the original BC sample, with the BC–ALG–CS composite showing the best characteristics.

Bacterial cellulose (BC) is a nanofibrous biomaterial biosynthetized by a series of acetic bacteria with unique properties with application in many tissue engineering purposes. Calcium phosphates (CPs), mainly hydroxyapatite, are bioceramics that possess similar composition of host bones and are able to stimulate osteoconduction and osteointegration to living tissues. Bacterial cellulose-calcium phosphates composites have caught the attention of researchers by their excellent mechanical properties and biocompatibility, being considered an excellent proposal to development of new synthetic grafts to bone tissue engineering. The minireview presented here focuses on various fabrication methods used to prepare and novel applications of BC-CPs composites and their applications in BTE.Keywords:

“…After 4 weeks defects were observed to be filled in by new bone tissue revealing these BC-HA membranes as effective for bone regeneration. Other groups have also explored the benefits of hydroxyapatite integrated bacterial cellulose for a variety of medical material implementations [63]. The choice of the optimum conditions for the creation of the bone tissue precursor and the method of how the combined aggregation of hydroxyapatite and bacterial cellulose suspensions should be prepared is important.…”

“…Techniques include varying the ratio of components during combined aggregation of hydroxyapatite and bacterial cellulose suspensions, introducing the hydroxyapatite suspension in the growth medium during BC biosynthesis, and controlled synthesis of the hydroxyapatite from precursor ions dispersed in the medium during bacterial cellulose formation. Depending on these different methods of formation of the hydroxyapatite/BC composite the resulting nanotexture and alignment of the hydroxyapatite relative to the BC were found to be altered [63]. For example, the use of hydroxyapatite nanoparticles prepared from a wet chemical precipitation method from aqueous calcium nitrate and di-ammonium phosphate were pre-synthesized before incorporating into the culture media during biosynthesis of BC nanofibrils [64].…”

Increasing interest in bacterial cellulose due to the huge potential which exists for the development of this new biomaterial for medical applications has been met with recent growth in research in engineering this unique microbial manufactured material. The mechanical properties, porosity, and biocompatibility of bacterial cellulose derived biomaterials are particularly attractive for use in wound healing, tissue engineering, and drug delivery applications. Advances in synthetic biology and soft materials engineering are pushing the value of this biomaterial to new levels. This review provides and in-depth discussion of these most recent approaches in processing as well as physical, chemical, and genetic modification of bacterial cellulose toward further improvement and expansion of its functionality. In addition, we provide specific attention to the marketed applications of the resulting engineered materials for medical research and conclude with prospective areas of consideration for expanding the clinical utility of this biomaterial to new directions.
