Dual role of a natural deep eutectic solvent as lipase extractant and transesterification enhancer
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG The present work demonstrates the suitability of a natural deep eutectic solvent (DES) composed of glucose and cholinium chloride to act both as lipase extractant and biodiesel enhancer. After having demonstrated the viability...
