Improving the activity and stability of enzymes is significant in enzyme immobilization. Here a facile approach to prepare ring-like ZIF-8 colloidosomes and spherical catalase-embedded ZIF-8 colloidosomes is developed via one-step emulsion-based technique at the water/butanol interface. The influence of the concentrations of ZIF-8 nanocrystals and Pluronic F127 as well as the oil-water ratio was investigated. Compared with in situ biomineralization, the colloidosomes prepared via the pickering emulsion method show successful encapsulation of positively charged enzymes. By using catalase as an immobilized model, the immobilized catalase exhibits high biocatalytic activity, stability and recyclability compared with free catalase.

“…In addition, a material with poor thermal stability or reusability cannot be used as a carrier of immobilized enzyme instead, it would be better that the material has magnetic property, which is helpful for its separation from the reaction using a magnetic field. Chen et al . demonstrated a strategy for attaching magnetic Fe 3 O 4 nanoparticles onto the commercially available immobilized lipase by adsorption.…”

Magnetic porous polymeric microspheres containing epoxy groups were prepared by suspension polymerization (denoted as magnetic Fe 3 O 4 @GEM microspheres). Fe 3 O 4 @GEM with a specific surface area of 30.41 m 2 /g, average pore diameter of 17.13 nm, and pore volume of 0.13 cm 3 /g exhibited superparamagnetic behavior with the saturation magnetization of 7.1 emu/g. The content of epoxy groups on Fe 3 O 4 @GEM was 0.22 mmol/g. Pseudomonas sp. lipase (PSL) was covalently immobilized onto the Fe 3 O 4 @GEM microspheres through the reaction between the amino groups of the enzyme and the epoxy groups on the microspheres. PSL/Fe 3 O 4 @GEM exhibited enhanced enantioselectivity for the resolution of allylic alcohol to the corresponding optically active (S)allylic alcohol and (R)-allylic alcohol acetate compared to free PSL. The enantiomeric excess of (S)-l-pheny-2-propen-1-ol for the former (98.1%) was 81.7 times that of the latter (1.2%) when the immobilized PSL was used for transesterification resolution of (R,S)-l-pheny-2-propen-1-ol. Furthermore, the ee s and ee p values were still retained at 95.2% and 95.4% after PSL/Fe 3 O 4 @GEM was recycled 10 times, indicating that PSL/Fe 3 O 4 @GEM had very good reusability. In addition, the transesterification resolution of (R,S)-1-(4-methylphenyl)-2-propen-1-ol and (R,S)-1-(4-bromophenyl)-2-propen-1-ol was catalyzed by PSL/Fe 3 O 4 @GEM, affording ideal ee s and ee p values of 99.3%, 97.4% and 99.6%, 98.2%, respectively. Therefore, PSL/Fe 3 O 4 @GEM demonstrated its potential as a highly efficient enzymatic reactor and Fe 3 O 4 @GEM would be very promising carriers for immobilizing enzymes in industrial application.

BACKGROUND Non‐edible oil such as Jatropha oil has high free fatty acids (FFAs) content. Therefore, acid esterification is a suitable route to reduce its FFA content to an acceptable limit (2 FFA%) before being subjected to further transesterification. In the present study, Jatropha seeds were utilized as the feedstock directly instead of Jatropha oil during ultrasound‐assisted in situ esterification. The objective of this work is to evaluate the feasibility of in situ esterification of Jatropha oil seeds using sulphuric acid (H2SO4) as catalyst with the aid of ultrasound. RESULTS The reaction parameters (particle size, n‐hexane to methanol volume ratio, H2SO4 amount, reaction time and ultrasonic amplitude) were optimized and evaluated in term of extraction and esterification efficiencies as well as fatty acid methyl ester (FAME) yield. The highest extraction efficiency of 83.96%, esterification efficiency of 71.10% and FAME yield of 38.58% were achieved at particle size of 1–2 mm, n‐hexane to methanol volume ratio of 3:1, 5 vol% of H2SO4 and ultrasonic amplitude of 60% with reaction time of 150 min. CONCLUSION Synthesis of biodiesel via ultrasound‐assisted in situ esterification of Jatropha oil seeds was successful with considerable yield, which could provide improvement in terms of process intensification and more value added by‐products. © 2018 Society of Chemical Industry
