Journal ArticleDOI
On the taught new tricks of enzymes immobilization: An all-inclusive overview
TL;DR: This review describes the choices of support materials and cross-linkers together with several mechanisms that influence the performance, stabilization and hyperactivation of immobilized enzymes.
Journal ArticleDOI
Structure and properties of oil palm-based nanocellulose reinforced chitosan nanocomposite for efficient synthesis of butyl butyrate
Nursyafiqah Elias,Sheela Chandren,Nursyafreena Attan,Naji Arafat Mahat,Fazira Ilyana Abdul Razak,Joazaizulfazli Jamalis,Roswanira Abdul Wahab +6 more
TL;DR: NMR analyses on the purified butyl butyrate confirmed that the ester was successfully synthesized and its suitability as nano-fillers for preparing the chitosan/nanocellulose (CS-NC) supports to immobilize Candida rugosa lipase (CRL) to produce the CRL/ CS-NC biocatalysts.
Journal ArticleDOI
Characterization, optimization and stability studies on Candida rugosa lipase supported on nanocellulose reinforced chitosan prepared from oil palm biomass.
Nursyafiqah Elias,Sheela Chandren,Fazira Ilyana Abdul Razak,Joazaizulfazli Jamalis,Nashi Widodo,Roswanira Abdul Wahab +5 more
TL;DR: This research provides a promising approach for expanding the use of NC from OPFL for enhancing enzyme activity in favour of an alternative eco-friendly means to synthesize butyl butyrate.
Journal ArticleDOI
Effect of operative variables and kinetic study of butyl butyrate synthesis by Candida rugosa lipase activated by chitosan-reinforced nanocellulose derived from raw oil palm leaves.
Nursyafiqah Elias,Roswanira Abdul Wahab,Sheela Chandren,Fazira Ilyana Abdul Razak,Joazaizulfazli Jamalis +4 more
TL;DR: The kinetics data conclusively showed that CRL/CS-NC was catalytically more efficient than free CRL (Vmax 0.48 mM min-1, Keff 0.07 min-1’mM-1) and Butanol was preferred over butyric acid as reflected by the higher apparent Michaelis-Menten constant of CRL/.
Journal ArticleDOI
Taguchi orthogonal design assisted immobilization of Candida rugosa lipase onto nanocellulose-silica reinforced polyethersulfone membrane: physicochemical characterization and operational stability
Nursyafiqah Elias,Roswanira Abdul Wahab,Lau Woei Jye,Naji Arafat Mahat,Sheela Chandren,Joazaizulfazli Jamalis +5 more
TL;DR: In this article, the covalent immobilization of Candida rugosa lipase (CRL) onto biomass-based nanocellulose-silica (NC-SiO2) reinforced polyethersulfone (PES) membrane to synthesize pentyl valerate (PeVa) was explored.
