“…55 Tavares et al opted for ethylene glycol as a plasticizer in a xanthan-based polymer electrolyte. 51 It was noted that the plasticizer decreased the degree of crystallinity, thus improving the ionic conductivity.…”

“…The mechanical properties of polymer electrolytes vary depending on the concentration of the cross-linking agent . Some cross-linking agents used in biopolymer-based electrolytes are formaldehyde, poly(ethylene glycol) diacrylate, and glutaraldehyde, among others. − A polymeric network can also be obtained without the use of chemical cross-linkers. This is the case of bacterial cellulose (BC), which is naturally synthesized as an entangled network of cellulose nanofibers.…”

Bacteria can naturally synthesize a wide range of biopolymers that have appealing material properties for numerous applications. In the past decade, the development of green electronics based on bacterial polymers has gained major attention. Polymer electrolytes are key components in electrochemical devices owing to their mechanical properties, thermal stability, and ionic conductivity. The present review focuses on the recent progress of bacterial-polymer-based electrolytes and their applications in electrochemical energy conversion and storage. First, we described the ion transfer mechanism of polymer electrolytes and the multiple approaches for improving ionic conductivity and mechanical properties. Then, we summarized the composition, performance, and approaches applied for the development of multiple bacterial polymer electrolytes, namely, polysaccharides, polyanhydrides, and polyesters. Lastly, the practical applications of bacterial-polymer-based electrolytes in electrochemical energy storage and conversion, namely, fuel cells, batteries, supercapacitors, and other electrochemicals, are reviewed. Bacterial polymer electrolytes are presented as a fruitful, eco-friendly, and high-performance alternative for traditional solid polymer electrolytes.

“…Xanthan is a branched polysaccharide, the backbone of which consists of β-(1,4) linked d -glucose units with side chains consisting of d -glucuronic acid unit between two d -mannose units attached to every second glucose residue in the backbone [65]. Xanthan is produced via fermentation by bacteria from, e.g., agro-industrial wastes such as straw, corn cobs or fruit peels [66].…”

Polysaccharide hydrogels have been increasingly utilized in various fields. In this review, we focus on polysaccharide-based hydrogels used as probiotic delivery systems. Probiotics are microorganisms with a positive influence on our health that live in the intestines. Unfortunately, probiotic bacteria are sensitive to certain conditions, such as the acidity of the gastric juice. Polysaccharide hydrogels can provide a physical barrier between encapsulated probiotic cells and the harmful environment enhancing the cells survival rate. Additionally, hydrogels improve survivability of probiotic bacteria not only under gastrointestinal track conditions but also during storage at various temperatures or heat treatment. The hydrogels described in this review are based on selected polysaccharides: alginate, κ-carrageenan, xanthan, pectin and chitosan. Some hydrogels are obtained from the mixture of two polysaccharides or polysaccharide and non-polysaccharide compounds. The article discusses the efficiency of probiotic delivery systems made of single polysaccharide, as well as of systems comprising more than one component.

“…Biopolymers offer a wide range of benefits as they are biodegradable, renewable, abundant, and non-hazardous compared to synthetic polymers. Innovative SPEs based on cellulose and its derivatives [2,3,4], deoxyribonucleic acid (DNA) [5,6] , gelatin [7,8,9], chitosan [10,11], corn starch [12,13], agar [14,15], xanthan gum [16] and silk fibroin [17], were introduced. In the same context, we explored the use of the red-seaweeds-derived carrageenan (Cg) acid polysaccharides [18].…”

In recent years, the synthesis of polymer electrolyte systems derived from biopolymers for the development of sustainable green electrochemical devices has attracted great attention. Here electrolytes based on the red seaweeds-derived polysaccharide κ-carrageenan (κ-Cg) doped with neodymium triflate (NdTrif3) and glycerol (Gly) were obtained by means of a simple, clean, fast, and low-cost procedure. The aim was to produce near-infrared (NIR)-emitting materials with improved thermal and mechanical properties, and enhanced ionic conductivity. Cg has a particular interest, due to the fact that it is a renewable, cost-effective natural polymer and has the ability of gelling in the presence of certain alkali- and alkaline-earth metal cations, being good candidates as host matrices for accommodating guest cations. The as-synthesised κ-Cg-based membranes are semi-crystalline, reveal essentially a homogeneous texture, and exhibit ionic conductivity values 1–2 orders of magnitude higher than those of the κ-Cg matrix. A maximum ionic conductivity was achieved for 50 wt.% Gly/κ-Cg and 20 wt.% NdTrif3/κ-Cg (1.03 × 10−4, 3.03 × 10−4, and 1.69 × 10−4 S cm−1 at 30, 60, and 97 °C, respectively). The NdTrif-based κ-Cg membranes are multi-wavelength emitters from the ultraviolet (UV)/visible to the NIR regions, due to the κ-Cg intrinsic emission and to Nd3+, 4F3/2→4I11/2-9/2.
