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: The study focuses on the synthesis of gamma-valerolactone (GVL) from butyl levulinate (BL) hydrogenation using sulfonated activated carbon (SAC) supported SnRuB bifunctional catalysts. The optimal 20Sn1RuB/SAC catalyst showed high BL conversion and GVL selectivity, attributed to the active surface species and strong interaction between SnRuB active site and SAC support. The catalyst also exhibited excellent recyclability in six runs, making it a potential candidate for cost-effective and efficient BL hydrogenation to GVL.

Summary: In this study, stigmasteryl oleate was efficiently synthesized via lipase catalysis under optimized ultrasound pretreatment conditions, and its physicochemical properties were investigated. The results showed a high conversion rate of stigmasterol under specific ultrasound and enzyme conditions. The synthesized stigmasteryl oleate exhibited improved solubility and lower peroxide value compared to stigmasterol, making it more suitable for oil-based foods.

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.
