Summary: Gelatin is a costless polypeptide material capable of forming potentially useful hydrogels in biomaterial scaffold design, although it is unstable at physiological conditions. This study introduces the use of bi- and trifunctional tetrazoles for photoinduced gelatin cross-linking to produce physiologically stable hydrogels. The efficacy of the treatment depends on the structure of the cross-linking agent used, with substantial improvement observed by switching from bifunctional to trifunctional cross-linkers.

Summary: Gelatin-based hydrogels are widely used in various fields due to their biocompatibility and versatility. However, their poor thermal stability limits their applications. In this study, we investigated the use of glutaraldehyde and glyceraldehyde as cross-linking agents in gelatin hydrogels. We found that by adjusting the type and amount of the cross-linker, we can tune the properties of the hydrogels, including their dissolution behavior, micro- and nanostructure, and mechanical properties. These findings are important for finding alternative cross-linking agents without toxicity concerns.

Summary: Three-dimensional bioprinting is a powerful engineering method for developing cellular structures with unique mechanical and biological properties. This study establishes a direct mapping between the printability of a gelatin microgel-gelatin solution composite bioink and the concentration and cross-linking time of the transglutaminase (TG) enzyme. The results show that by optimizing the TG concentration and cross-linking time, the bioink exhibits good injectability, feature formability, and cell viability.

Summary: To control the rapid dissolution and high-speed drug release in oral drug delivery using gelatin, glutaraldehyde was used to cross-link gelatin. Gelatin nanoparticles (GNPs) carrying Gliclazide were prepared through a two-step dissolution method. Cross-linking of gelatin with glutaraldehyde was confirmed by the presence of an aldimine functional group in GNPs. The drug release from GNPs was controlled by the swelling degree, with the highest and lowest release percentages observed in cross-linked GNPs with 8%v/v and 25%v/v glutaraldehyde, respectively.

Summary: This study investigated the impact of adding wheat straw on the anaerobic co-digestion of leather waste and its biogas production. The results showed that alkali treatment significantly increased the cellulose content of wheat straw, but inhibited methanogenesis, resulting in the lowest biogas production. However, the highest biogas yield was achieved when wheat straw was pretreated with acid, indicating its potential as an alternative for co-digestion.

Summary: The food industry is interested in extending the shelf life of food, and therefore, edible films and coatings have been explored as a solution. This study focuses on whey-based films for food packaging, which have unique characteristics such as antimicrobial and immunomodulatory properties. Various compounds can be incorporated into whey films to improve their solubility and mechanical properties. Meat and cheese are the most commonly studied food matrices for application. Edible and biodegradable films offer potential to replace synthetic polymers and have social, environmental, and economic benefits.

Summary: This study examined the effects of annealing and oxidation on native wheat starch for use in biodegradable films. The modified starches were evaluated for various properties and then used to create films, which were compared to films made with native starch. Annealing led to a reorganization of starch molecules, resulting in more stable films with fewer changes in mechanical properties and solubility. On the other hand, oxidation caused more drastic changes, including a heterogeneous structure and decreased elongation. The annealing treatment showed promise for developing biodegradable packaging with superior properties to chemically modified starch films.

Summary: Heavy metals contamination poses risks to ecosystems and human health. Bioremediation using biochar as a carrier for immobilized bacteria has emerged as an alternative to improve efficiency in environments with high concentrations of heavy metals. Bacillus spp. strains immobilized on biochar can reduce the toxicity and bioavailability of metals through biomineralization, biosorption, bioreduction, bioaccumulation, and adsorption mechanisms. This strategy promotes the reduction of toxicity and accumulation of metals in plants, enhances microbial and enzymatic activity in soil, but may also lead to competition and reduction of microbial diversity, as well as toxic characteristics of biochar. Further studies are needed to optimize this technology and understand its impacts, especially in field-scale applications.
