Hypothesis
Can immobilized lipase from Enterobacter aerogenes effectively catalyze the transesterification of Jatropha oil in the presence of t-butanol?
Conclusion
The study demonstrates that biodiesel can be efficiently synthesized from Jatropha oil using immobilized E. aerogenes lipase in t-butanol, achieving a maximum yield of 94%.
Supporting Evidence
- The maximum yield of biodiesel was 94% with a specific oil:methanol molar ratio and enzyme concentration.
- Immobilized lipase showed negligible loss of activity even after seven cycles of use.
- Using t-butanol reduced the negative effects of methanol and glycerol on lipase activity.
Takeaway
Scientists found a way to make biodiesel from Jatropha oil using a special enzyme, which worked really well when mixed with a certain type of alcohol.
Methodology
Transesterification of Jatropha oil was performed using immobilized lipase from Enterobacter aerogenes in t-butanol solvent, with various reaction parameters studied.
Limitations
The study primarily focuses on the use of t-butanol and does not explore other potential solvents or long-term operational stability beyond 20 cycles.
