摘要: Abstract The paper seeks to immobilize Candida rugosa lipase (CRL) on Chromium terephthalate MIL-101 (MIL-101(Cr)) and its three chemically modified forms: amino MIL-101(Cr) (NH2-MIL), trichlorotriazine (TCT@NH2-MIL) glutaraldehyde (Glu@NH2-MIL). synthesis process of these metal organic frameworks, CRL immobilization the morphology supports were verified using FTIR, PXRD, BET FE-SEM techniques. enzyme loading specific activity at different initial concentration for all measured obtained results compared. highest any given point in common range belongs CRL@Glu@NH2-MIL. While immobilized CRLs show no significant drop residual after pH stress, thermal stability is just substantially improved CRL@TCT@NH2-MIL About 80–90% enzymatic retained 35 days indicating a storage CRLs.
