“…Although chemically identical to plant cellulose, BC is characterized by a unique fibrillar nanostructure which determines its distinguished physical and mechanical properties such as high porosity, large surface area, excellent mechanical strength and good biocompatibility ( Bielecki et al, 2002 ; Gama et al, 2012 ). Therefore, BC has been used widely for making high-quality audio membranes, electronic paper, membranes for fuel cells, and biomedical materials ( Bielecki et al, 2002 ; Shah and Brown, 2005 ; Klemm et al, 2006 ; Petersen and Gatenholm, 2011 ; Gama et al, 2012 ; Jiang et al, 2012 , 2015 ; Hong et al, 2015 ; Tang et al, 2015 ). Already today, several attempts including development of cost-effective feedstocks from agroindustrial residues ( Hong et al, 2011 , 2012 ; Cavka et al, 2013 ; Chen et al, 2013 ; Guo et al, 2013 , 2015 ) and establishment of new cultivation methods ( Sani and Dahman, 2010 ) have been made to decrease the production cost of BC.…”

The aim of this work was to assess the possibility of using native bacterial nanocellulose (BC) as a carrier for laccase immobilization. BC was synthesized by Gluconacetobacter xylinus, which was statically cultivated in a mannitol-based medium and was freeze-dried to form BC sponge after purification. For the first time, fungal laccase from Trametes versicolor was immobilized on the native nanofibril network-structured BC sponge through physical adsorption and cross-linking with glutaraldehyde. The properties including morphologic and structural features of the BC as well as the immobilized enzyme were thoroughly investigated. It was found that enzyme immobilized by cross-linking exhibited broader pH operation range of high catalytic activity as well as higher running stability compared to free and adsorbed enzyme. Using ABTS as substrate, the optimum pH value was 3.5 for the adsorption-immobilized laccase and 4.0 for the crosslinking-immobilized laccase. The immobilized enzyme retained 69% of the original activity after being recycled seven times. Novel applications of the BC-immobilized enzyme tentatively include active packaging, construction of biosensors, and establishment of bioreactors.

“…Despite this, the current price of this bacterial cellulose is still considered as too high for certain applications. The study of bacterial cellulose polymer electrolytes only started in 2015, and since then, only two studies have been reported [55,56]. Both studies successfully recorded high ionic conductivity similar to that of liquid electrolytes.…”

With the continuing efforts to explore alternatives to petrochemical-based polymers and the escalating demand to minimize environmental impact, bio-based polymers have gained a massive amount of attention over the last few decades. The potential uses of these bio-based polymers are varied, from household goods to high end and advanced applications. To some extent, they can solve the depletion and sustainability issues of conventional polymers. As such, this article reviews the trends and developments of bio-based polymers for the preparation of polymer electrolytes that are intended for use in electrochemical device applications. A range of bio-based polymers are presented by focusing on the source, the general method of preparation, and the properties of the polymer electrolyte system, specifically with reference to the ionic conductivity. Some major applications of bio-based polymer electrolytes are discussed. This review examines the past studies and future prospects of these materials in the polymer electrolyte field.

“…In addition, adding nanocellulose into polymer electrolyte (e.g., Nafion) could not only improve the mechanical and thermal stability, but also reduce water uptake plus area and volume swelling ratios in proton conducting membrane, which is one of the essential and critical materials in both proton exchange membrane fuel cell (PEMFC) and direct methanol fuel cell (DMFC). The cross-linked structure formed by the nanocellulose could also effectively reduce the undesired methanol crossover [73][74][75][76].…”
