Enzymatic transesterification of Jatropha oil
BACKGROUND Transesterification of Jatropha oil was carried out in t-butanol solvent using immobilized lipase from Enterobacter aerogenes. The presence of t-butanol significantly reduced the negative effects caused by both methanol and glycerol. The effects of various reaction parameters on transesterification of Jatropha oil were studied. RESULTS The maximum yield of biodiesel was 94% (of whi...
متن کاملEnzymatic transesterification for biodiesel production.
Biodiesel consists monoalkyl esters of long chain fatty acids. It is produced from vegetable oils or fats either by chemical transesterification or by lipase-catalyzed transesterification with methanol or ethanol. Biodiesel is a green fuel and can be used as a blend with diesel or alone. Either way, it does not require any modification in engine design or storage facilities. The enzymatic proce...
متن کاملEvaluation of Chlorella (Chlorophyta) as Source of Fermentable Sugars via Cell Wall Enzymatic Hydrolysis
The cell wall of Chlorella is composed of up to 80% carbohydrates including cellulose. In this study, Chlorella homosphaera and Chlorella zofingiensis were evaluated as source of fermentable sugars via their cell wall enzymatic degradation. The algae were cultivated in inorganic medium, collected at the stationary growth phase and centrifuged. The cell pellet was suspended in citrate buffer, pH...
متن کاملProduction of Biodiesel by Enzymatic Transesterification: Review
Problem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel product...
متن کاملEffects of Condition Enzymatic Hydrolysis on Degrees of Hydrolysis and Antioxidant Activity of Head Protein of Bighead (Aristichthys nobilis)
Background and Objectives: Enzymatic hydrolysis is an effective practical technology that recovers valuable proteins from far-less farmed fish without losing their nutritional characteristics. Enzymatic hydrolysis of protein sources such as aquatic animals is a type of protein recycling. In the present study, effects of temperature, time and concentration of papain enzyme on hydrolysis degree a...
