“…Finally, new technological and advanced materials can be produced using SBP, as it is a good adhesive in particleboards for construction materials and can substitute toxic and petroleum‐derived adhesives [128] . Gels formed by SBP/xanthan gum with sodium chloride were shown to be promising materials for 3D printers, [129] and a transparent‐flexible supercapacitor can be developed using SBP and hydroxyethyl cellulose as the polymeric matrix and lithium sulfate as the electrolyte [130] …”

This Review highlights the principal crops of Brazil and how their harvest waste can be used in the chemicals and materials industries. The Review covers various plants; with grains, fruits, trees and nuts all being discussed. Native and adopted plants are included and studies on using these plants as a source of chemicals and materials for industrial applications, polymer synthesis, medicinal use and in chemical research are discussed. The main aim of the Review is to highlight the principal Brazilian agricultural resources; such as sugarcane, oranges and soybean, as well as secondary resources, such as andiroba brazil nut, buriti and others, which should be explored further for scientific and technological applications. Furthermore, vegetable oils, carbohydrates (starch, cellulose, hemicellulose, lignocellulose and pectin), flavones and essential oils are described as well as their potential applications.

“…Although currently, polyvinyl alcohol (PVA)-based gels are the most widely used electrolytes for solid-state supercapacitors, [ 1 , 18 ] biopolymer-derived systems are gaining increasing attention. For example, polysaccharides, [ 19 , 20 , 21 , 22 , 23 ] proteins and polypeptides, [ 24 , 25 , 26 , 27 ] and even synthetic polymers incorporating biological units, such as polyesteramides, [ 28 , 29 ] have been used to prepare hydrogels as solid-like electrolytes for manufacturing bioinspired supercapacitors. Indeed, their electrochemical response has been well studied by cyclic voltammetry and galvanostatic charge-discharge cycles; [ 1 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ] however, their ionic conductivity and capacitive properties remain unknown in many cases.…”

Flexible hydrogels are attracting significant interest as solid-like electrolytes for energy storage devices, especially for supercapacitors, because of their lightweight and anti-deformation features. Here, we present a comparative study of four ionic conductive hydrogels derived from biopolymers and doped with 0.1 M NaCl. More specifically, such hydrogels are constituted by κ-carrageenan (κC), carboxymethyl cellulose (CMC), poly-γ-glutamic acid (PGGA) or a phenylalanine-containing polyesteramide (PEA). After examining the morphology and the swelling ratio of the four hydrogels, which varies between 483% and 2356%, their electrical and capacitive behaviors were examined using electrochemical impedance spectroscopy. Measurements were conducted on devices where a hydrogel film was sandwiched between two identical poly(3,4-ethylenedioxythiophene) electrodes. The bulk conductivity of the prepared doped hydrogels is 76, 48, 36 and 34 mS/cm for PEA, PGGA, κC and CMC, respectively. Overall, the polyesteramide hydrogel exhibits the most adequate properties (i.e., low electrical resistance and high capacitance) to be used as semi-solid electrolyte for supercapacitors, which has been attributed to its distinctive structure based on the homogeneous and abundant distribution of both micro- and nanopores. Indeed, the morphology of the polyestermide hydrogel reduces the hydrogel resistance, enhances the transport of ions, and results in a better interfacial contact between the electrodes and solid electrolyte. The correlation between the supercapacitor performance and the hydrogel porous morphology is presented as an important design feature for the next generation of light and flexible energy storage devices for wearable electronics.

“…Another application of cellulose is nanocellulose materials, which are nontoxic, biodegradable, and biocompatible and have no adverse effect on the environment and human health. Because of their good physical and chemical properties, nanocelluloses are widely used in thermoreversible hydrogels, food packaging, flexible screens, coating additives, paper, optical transparent films, and biopharmaceuticals, for example [28][29][30][31].…”

Polysaccharides are biopolymers made up of a large number of monosaccharides joined together by glycosidic bonds. Polysaccharides are widely distributed in nature: Some, such as peptidoglycan and cellulose, are the components that make up the cell walls of bacteria and plants, and some, such as starch and glycogen, are used as carbohydrate storage in plants and animals. Fungi exist in a variety of natural environments and can exploit a wide range of carbon sources. They play a crucial role in the global carbon cycle because of their ability to break down plant biomass, which is composed primarily of cell wall polysaccharides, including cellulose, hemicellulose, and pectin. Fungi produce a variety of enzymes that in combination degrade cell wall polysaccharides into different monosaccharides. Starch, the main component of grain, is also a polysaccharide that can be broken down into monosaccharides by fungi. These monosaccharides can be used for energy or as precursors for the biosynthesis of biomolecules through a series of enzymatic reactions. Industrial fermentation by microbes has been widely used to produce traditional foods, beverages, and biofuels from starch and to a lesser extent plant biomass. This review focuses on the degradation and utilization of plant homopolysaccharides, cellulose and starch; summarizes the activities of the enzymes involved and the regulation of the induction of the enzymes in well-studied filamentous fungi.
