“…As the rst property from chemical aspect, there are numerous hydroxyl groups (-OH) onto the CLS strands that provide suitable chemically active sites for covalent bindings and well composition with pumice particles through physicochemical H-bindings. [29][30][31][32] From the other side, these active -OH functional groups are appropriate for chelation by cationic metals such as copper 33 and palladium. 34 From mechanical aspect, composition of the CLS textures with other inorganic components forms a stable hybrid structure that is considered as an important factor in the architecture of the heterogeneous catalytic systems.…”

“…Furthermore, many researchers demonstrated the use of CNS as support materials in heterogeneous catalyst systems and as containers for encapsulating organic nonpolar compounds, showing good loading efficiency. [225,177,226] The previous study reported that CNS used as drug carriers for controlled release and as templates to fabricate porous calcium carbonate microspheres, indicating potential applications in drug delivery. [227][228][229][230] Furthermore, Li et al encapsulated paraffin in CNF through a Pickering emulsion method, forming a composite material for phase change materials with potential application in smart building solutions.…”

Rising global food prices and the increasing prevalence of food insecurity highlight the imprudence of food waste and the inefficiencies of the current food system. Upcycling food by‐products holds significant potential for mitigating food loss and waste within the food supply chain. Food by‐products can be utilized to extract nanocellulose, a material that has obtained substantial attention recently due to its renewability, biocompatibility, bioavailability, and a multitude of remarkable properties. Cellulose nanomaterials have been the subject of extensive research and have shown promise across a wide array of applications, including the food industry. Notably, nanocellulose possesses unique attributes such as a surface area, aspect ratio, rheological behavior, water absorption capabilities, crystallinity, surface modification, as well as low possibilities of cytotoxicity and genotoxicity. These qualities make nanocellulose suitable for diverse applications spanning the realms of food production, biomedicine, packaging, and beyond. This review aims to provide an overview of the outcomes and potential applications of cellulose nanomaterials derived from food by‐products. Nanocellulose can be produced through both top‐down and bottom‐up approaches, yielding various types of nanocellulose. Each of these variants possesses distinctive characteristics that have the potential to significantly enhance multiple sectors within the commercial market.

“…The latter result probably indicates an additional unknown CO2 removal mechanism which was identified in the precipitation of an insoluble copper-based carbonate precipitate present on the side of the AEM membranes. In fact, the presence of a copper was determined by a qualitative assay (Figure S5) [32]. Table 1 summarized the different identified CO2 removal mechanisms during the two operational periods of the continuous flow bioelectrochemical reactor.…”

Autotrophic Acetate Production under Hydrogenophilic and Bioelectrochemical Conditions with a Thermally Treated Mixed Culture

et al. 2022

Bioelectrochemical systems are emerging technologies for the reduction in CO2 in fuels and chemicals, in which anaerobic chemoautotrophic microorganisms such as methanogens and acetogens are typically used as biocatalysts. The anaerobic digestion digestate represents an abundant source of methanogens and acetogens microorganisms. In a mixed culture environment, methanogen’s inhibition is necessary to avoid acetate consumption by the presence of acetoclastic methanogens. In this study, a methanogenesis inhibition approach based on the thermal treatment of mixed cultures was adopted and evaluated in terms of acetate production under different tests consisting of hydrogenophilic and bioelectrochemical experiments. Batch experiments were carried out under hydrogenophilic and bioelectrochemical conditions, demonstrating the effectiveness of the thermal treatment and showing a 30 times higher acetate production with respect to the raw anaerobic digestate. Moreover, a continuous flow bioelectrochemical reactor equipped with an anion exchange membrane (AEM) successfully overcomes the methanogens reactivation, allowing for a continuous acetate production. The AEM membrane guaranteed the migration of the acetate from the biological compartment and its concentration in the abiotic chamber avoiding its consumption by acetoclastic methanogenesis. The system allowed an acetate concentration of 1745 ± 30 mg/L in the abiotic chamber, nearly five times the concentration measured in the cathodic chamber.
