Special Issue Information

Dear Colleagues,

Catalysis is a vital area of research that enhances chemical processes, improving efficiency and selectivity while minimizing environmental impact. This Special Issue of Catalysts, "Recent Developments in Catalysis in Brazil", invites contributions that explore the latest advancements in both traditional and biocatalysis within the Brazilian context. With its diverse scientific landscape and rich natural resources, Brazil is uniquely positioned to make significant contributions to the field of catalysis. We welcome submissions that investigate various aspects of catalytic science, including the development of novel catalysts, advancements in catalytic mechanisms, and applications across sectors such as petrochemicals, pharmaceuticals, and green chemistry. Contributions highlighting biocatalysis, particularly the use of enzymes in sustainable processes, are especially encouraged, as they represent a growing area of research and application in Brazil.

This Issue aims to provide a comprehensive overview of both fundamental studies and applied research, showcasing the breakthroughs and methodologies that are driving progress in catalysis. By sharing findings and experiences, we hope to foster collaboration and inspire further innovation in catalytic technologies, positioning Brazil as a key player in the global catalysis landscape.

The aqueous enzymatic extraction (AEE) of oil from Thevetia peruviana seeds was studied. The oil extraction yields obtained by treatment with cellulase, Alcalase, and Viscozyme L were compared, finding that the treatment with Alcalase at pH 6 and 50 °C gave the highest yield (63.07%), so it was selected for the optimization of the oil extraction process through a central composite design and a response surface methodology. An oil extraction yield of 78.22% was achieved under the optimum conditions (2% of Alcalase, 4 h of incubation, 250 rpm, and a solid-to-liquid ratio of 1:4.5). The predominant fatty acids in the oil obtained by both AEE and standard solvent extraction (SE) were oleic, linoleic, stearic, and palmitic acids. However, AEE produced an oil presenting lower acidity and peroxide values and greater oxidative stability, indicating that this method produces an oil with better quality. Scanning electron microscopy images of Thevetia peruviana seeds showed a structural alteration of their cell wall caused by AEE, which allowed the release of oil from this seed in the aqueous medium. The results suggest that AEE could be an excellent alternative in terms of efficiency, oil quality, and environmental friendliness for the extraction of this oil. Full article
