Summary: A green strategy was demonstrated to accelerate the biodegradation rate of cellulose acetate (CA) through deacetylation. The immobilization of lipase from Candida rugosa on CA particles resulted in significant deacetylation, as evidenced by changes in molecular weight and water contact angle. This approach showed promising potential for developing modified lignocellulose materials with retained biodegradability.

Summary: Enzyme immobilization is an efficient method for stabilizing, separating, and reusing costly and difficult-to-extract enzymes used in industrial biocatalysts. A 3D porous functionalized polypyrrole material with superior properties was designed for covalently immobilizing model enzymes. By using different molecular weights of biodegradable carboxymethylcellulose crosslinker, the strength of the porous aggregates was altered, resulting in improved performance. The increased specific surface area and optimal pore size facilitated enzyme diffusion and retention, leading to higher specific activity and stability in Candida rugosa and Candida Antarctica, commonly found in commercial biocatalysts.

Summary: The chemoenzymatic epoxidation of olefin mediated by lipase is an environmentally friendly alternative process. In this study, we investigated the effects of reaction temperature and two substrates on the epoxidation reaction and interfacial mass transfer. Optimal conditions were determined and a batch reactor with a metal mesh was designed to block direct contact between high-concentration hydrogen peroxide and the enzyme. Under these conditions, a maximum product yield of 93.2% was achieved and the lipase maintained a relative activity of 51.2% after repetitive experiments.

Summary: Fungal lipases are important industrial enzymes with numerous applications in various fields. They are carboxylic acid esterases belonging to the serine hydrolase family, and can be easily extracted and purified from fungi. Fungal lipases have applications in hydrolyzing fats and oils, as well as in synthetic reactions such as esterification and interesterification. They are affected by factors such as carbon source, nitrogen source, temperature, pH, metal ions, surfactants, and moisture content. Immobilizing fungal lipases onto different carriers improves their catalytic activities and efficiencies, making them suitable as biocatalysts in industries.

Summary: In this study, polyacrylonitrile (PAN) modified with hexamethylene diamine (HMDA) and glutaraldehyde activation was utilized as a carrier for immobilizing Candida rugosa lipase. The immobilized lipase showed the highest activity at pH 8.0, with a yield of 81% and an activity of 91%. After recycling and storage, the immobilized lipase maintained a significant percentage of its initial activity. The results suggest that synthetically modified PAN is a suitable support for enzyme immobilization and has potential for commercial applications.

Summary: Esterases are extensively studied enzymes with various applications in industrial biotechnology. However, their substrate specificity cannot be predicted solely from their amino acid sequence. In this research, the newly discovered hydrolytic extremozyme, EstDZ3, was investigated for its substrate scope against esters with different carbon chain lengths to determine the crucial amino acids responsible for its substrate selectivity. EstDZ3 exhibited activity against a wide range of esters, with high selectivity towards medium- to long-carbon chain vinyl esters. In-silico studies of its 3D structure suggested that the selectivity might be attributed to the hydrophobic nature of its active site environment.

Summary: In this study, a new temperature-responsive nanocarrier based on halloysite nanotubes and poly(N-isopropylacrylamide) brushes was designed and characterized. The hybrid material showed a phase transition temperature of about 32 degrees C, and exhibited temperature-dependent drug release. Cell studies confirmed reduced cytotoxicity due to the poly(N-isopropylacrylamide) brushes, and drug release studies demonstrated the controlled release of doxorubicin. Additionally, the internalization of the nanotubes in HeLa cells was confirmed using stimulated emission depletion nanoscopy.

Summary: The synthesis and design of two-dimensional supramolecular assemblies with specific functionalities is a challenging goal in molecule-based electronics. In this study, we report a novel approach to prepare wide highly crystalline molecular assemblies with tunable structural properties. By utilizing the reactivity of carboxylic acid functional moiety and the predictable features of non-polar alkane chains, we successfully synthesized 2D supramolecular assemblies on a Au(111) surface. These assemblies showed a self-limited highly ordered and defect-free two-dimensional single-layer film of micrometer-size, which could be modified in a controlled way by changing the length of the alkane chains.

Summary: The incidence of skin cancer has increased significantly in recent decades. Conventional therapeutic methods have limitations, so it is necessary to develop effective treatments. Modern delivery systems, such as nanofiber-based systems, have the potential to overcome complications associated with skin cancer. Electrospinning is a versatile technique that can fabricate nanofibers using natural and synthetic polymers, offering advantages for encapsulating therapeutic agents and preventing the harmful effects of radiation exposure. Additionally, incorporating therapeutic nanostructures, such as metal and magnetic nanoparticles, into nanofibers allows for multimodal treatments. This study discusses various nanofibrous-based strategies and their effectiveness in treating skin cancers.

Summary: In the field of biocatalysis, the implementation of sustainable processes such as enzyme immobilization or the use of environmentally friendly solvents is highly important. This study focused on the extraction of tyrosinase from fresh mushrooms and its carrier-free immobilization to create non-magnetic and magnetic cross-linked enzyme aggregates (CLEAs). The results showed that the nature and concentration of Deep Eutectic Solvents (DESs) significantly affected the catalytic activity and stability of tyrosinase, with immobilization increasing the enzyme's activity up to 3.6-fold. The biocatalyst also demonstrated great potential in modifying chitosan with caffeic acid, enhancing the films' antioxidant activity.

Summary: Nanostructured hybrids of graphene oxide and palladium were synthesized through one-step solvent-free gas phase treatment, followed by in situ decoration with palladium in the liquid medium. The proposed method offers an eco-friendly alternative for obtaining nanohybrids of graphene oxide and palladium nanoparticles under mild conditions. The hybrids demonstrated the formation of nanometer-sized crystalline palladium particles, with larger particle sizes observed for diamine-functionalized substrates compared to monoamine or non-functionalized substrates. The thermal stability of the obtained hybrids was slightly lower than pristine graphene oxide.

Summary: The thermal properties of polymers depend on their chemical structure and intermolecular forces. By chemically modifying polyketones and increasing the amount of supramolecular interactions, the glass transition temperature of polyketones can be tuned. The research shows that modification with aminomethyl benzoic acid and aminohexanoic acid introduces new hydrogen bonding possibilities and significantly increases the glass transition temperature, while modification with an imidazole derivative introduces new and stronger pi-pi interactions.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
