“…Jantasrirad et al 306 recently showed that the use of sonicated brown algae filler in a starch biopolymer matrix at 10 wt% filler concentration led to 330% and 230% improvements in the strength compared to neat starch biopolymer and the equivalent biocomposite with non‐sonicated filler, respectively. The improvements in reinforcing effects following sonication of the algal filler suggests that physical processing to the filler can offer an alternative viable strategy to improve the performance of biocomposites.…”

The mass production and disposal of non‐degradable fossil‐based plastics is responsible for alarming environmental and social issues when not managed responsibly. Towards manufacturing environmentally‐friendly materials, biopolymers, that is, polymers synthesized by living organisms, emerge as promising sustainable alternatives as they combine attractive mechanical properties, compostability, and renewable sourcing. In this review, we analyze the structural and mechanical properties of three of the most studied biopolymer classes: cellulose, chitin, and protein beta‐sheet structures. We first discuss the hierarchical structure of the biopolymers and how their rich interaction networks induce appealing mechanical properties. Then, we review different fabrication and processing methods to translate these attractive properties into macroscopic materials and composites. Finally, we discuss a nascent approach, which leverages the direct use of microorganisms, in the form of intact cells, tissues or dissociated biological matter (biomatter), as meso‐scale material building blocks. These non‐ or little pre‐processed biomatter building blocks are composed of the biopolymer structural elements (molecular‐nano scale), but also inherit the higher‐scale hierarchical characteristics. Processing‐structure–property relationships for biomatter‐based materials are discussed, emphasizing on the role of hierarchical arrangement, processing‐induced transformations, and intermolecular bonding, on the macroscopic mechanical properties. Finally, we present a perspective on the role of biopolymers in a circular economy.

This paper extracts alginate of Dictyota mertensii (DM), brown macroalgae found on the north coast of northeastern Brazil. A Composite Central Design (CCD) associated with Response Surface Methodology (RSM) was employed to optimize the extraction process of different fractions of alginate, in different conditions of time, temperature, and concentration of Na2CO3. Yield (𝜂), sulfate content, intrinsic viscosity ([𝜂]), viscosimetric molar mass (Mv), color parameters (a*, b* e L*), and M/G ratio are model response variables. The DM algae has its chemical composition expressed. Response surfaces are plotted from the variables studied, quadratic models were predicted, the influence of factors is analyzed, and response variables are subjected to analysis of variance (ANOVA) and F-test at 95% confidence. The antioxidant potential was evaluated based on the scavenging of the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). The maximum extraction yield was 29.28±0.02 %, and sulfate content ranged from 3.50±0,00 % to 12.33±0.29 %. The maximum values of [𝜂] and Mv were 5.84±0.06 dL.g-1 and 278.00±2.66 kDa, respectively. The alginate showed a dark brown color and M/G ratio <1, indicating that the extracted alginate provides rigid and compact gels. The antioxidant potential and the CI50 were 54.93±0.27% and 0.51±0.07 mg.mL-1 , respectively, indicating moderate antioxidant activity.

In this work, brown alga (Sargassum plagiophyllum) was utilized as a reinforcement material to produce wheat gluten (WG) biocomposites. The effect of brown alga powder (BP) content and sonication treatments of BP on the properties of the obtained WG biocomposites were characterized. Adding 1 wt% BP to WG increased the tensile strength by 77% compared to neat WG and could delay the degradation process of the WG biocomposites due to the good interaction between BP and the WG matrix. When the time and amplitude of BP sonication was increased, the tensile strength of the obtained WG biocomposites slightly decreased, but still remained higher than the tensile strength of the neat WG. Therefore, this work presents an efficient reinforcement material and a potential treatment process to produce promising alternative biocomposites for the production of environment friendly materials.biopolymers and renewable polymers, molding, proteins | INTRODUCTIONWheat gluten (WG) is a by-product of wheat starch production and other food processes. 1,2 The structure of WG comprises two major proteins, gliadin, and glutenin. WG is prominent among plant proteins (WG, soya, and zein), due to its wide availability, renewability and biodegradability and is used commercially in various applications for its unique viscoelastic properties. It is used as a binder for paper coatings, in adhesive tapes, cosmetics, textiles, and medical and bioplastic packaging. 3,4 For the last of those applications, WG can be processed into bioplastic by the addition of plasticizers before treatment either by solvent casting or common thermoplastic processes such as extrusion or thermomolding. 2,4,5 However, the performance of WG-based bioplastics is severely limited when compared with materials based on synthetic polymers. The strength and thermal stability of WG-based bioplastics are low and WG-based bioplastics have a strong tendency to absorb moisture. 3,5 One way to improve the performance of bioplastics is to include reinforcing filler materials and recently, the reinforcement of WG-based bioplastics with bio-based materials has gained increasing attention. The filler materials used have included rubber wood sawdust, fish scale, shrimp shell, palm empty fruit bunch fiber, banana fiber and pine char. The method is simple and highly effective and these bio-based materials are sustainable
