Evaluation of lipase from Burkholderia cepacia immobilized in alginate beads and application in the synthesis of banana flavor (isoamyl acetate)

Biodiesel production from waste cooking oil

“…The literature contains many examples of self-dual Leonard pairs. For instan ated with an irreducible module for the Terwilliger algebra of the hypercube (see Leonard pair of Krawtchouk type (see [10, De nition 6.1]); (iii) the Leonard pair a module for the Terwilliger algebra of a distance-regular graph that has a spin m bra (see [1,Theorem], [3,Theorems 4.1, 5.5]); (iv) an appropriately normalized (see [11,Lemma 14.8]); (v) the Leonard pair consisting of any two of a modular De nition 1.4]); (vi) the Leonard pair consisting of a pair of opposite generato bra, acting on an evaluation module (see [5,Proposition 9.2]). The example (i) is examples (iii), (iv) are special cases of (v).…”

“…Enzymes catalyzed processes have great potential compared to chemical methods [11,12]: intrinsic low environmental impact, no need of pretreatments to remove water, FFAs, etc., high efficiency and conversion of free fatty acids, lower energy consumption, mild conditions during the reactions, product purity and facilitated separation of glycerol are the main advantages of the enzymatic processes [13]. The process of transesterification is affected by different variables.…”

“…The process of transesterification is affected by different variables. The enzymatic production of biodiesel can be influenced by many aspects such as activity, stability and specificity of the enzyme, alcoholoil ratio, temperature and water content [11,14,15]. On the other hand, the enzymes can give high biodiesel yields and can exhibit reaction times comparable to those of base catalysts, requiring, in general, higher amounts of catalyst but lower of alcohol [16].…”

The beauty of biocatalysis: sustainable synthesis of ingredients in cosmetics

“…320–322 For improved sustainability and reduction in production costs, the lipase is often immobilised. 323,324 Fusel oil (a by-product of bioethanol industry) can be used as the isoamyl alcohol source. 325…”

Incorporation of metallic particles in activated carbon used in lipase immobilization for production of isoamyl acetate

“…7 In this sense, enzymes and microbial sources have been employed in ester production as they offer advantages over conventional technologies. 8 A biotechnological process offers a higher yield than chemical synthesis and accelerates reactions up to 10 8 -10 15 times, requires moderate conditions for reaction and the product generated can be characterized as natural, being a promising field for the food industry. 3,9 In recent years, the use of enzymes to catalyze esterification reactions has been extensively studied.…”
