“…This result corroborates the general observation in immobilized enzyme cataysis, that the enzyme activity is improved when compared with its free counterpart (Netto et al, 2009;2011). Although the catalyst achieved a high soybean oil into biodiesel conversion during the first reaction, the efficiency of the transesterification reaction gradually decreased in the subsequent cycles, particularly after the third cycle (Fig.…”

“…Supermagnets of Nd2Fe14B displaying strong magnetic fields are quite available in the market, and are suitable for this purpose. However, one has to carefully consider the biomolecule linking procedure to the nanoparticle beforehand, since the coupling method can impact the enzyme catalytic activity and its immobilization efficiency (Rebelo et al, 2010;Netto et al, 2009Netto et al, , 2011Netto et al, , 2012Netto et al, , 2013Netto et al, , 2015. A large variety of methods has already been employed (Netto et al, 2013); however, they have led to very contrasting results.…”

-Candida antarctica Lipase B (CALB) immobilized onto iron magnetic nanoparticles was evaluated as biocatalyst for the synthesis of flavor esters. Methyl and ethyl butyrate were synthesized by esterification of butyric acid with methanol and ethanol, respectively, in a medium containing solvent. The nanoparticles were produced by the co-precipitation method. The process parameters (type of solvent, temperature, substrate concentration, molar ratio, amount of biocatalyst, stirring speed and reaction time) were studied. The optimum conditions for both esters were achieved at 25 °C, 0.5 mol/L (methyl butyrate) and 0.4 mol/L (ethyl butyrate), molar ratio of 1:1, amount of biocatalyst: 10 mg, 150 rpm and 8 h of reaction, using heptane as solvent. Under those conditions, the maximum conversions of methyl butyrate and ethyl butyrate were higher than 90 %. The synthesis of flavor esters was also conducted by using Novozym® 435, a commercial catalyst, for comparison purposes.

“…To overcome these issues, many researchers have studied enzyme immobilization using magnetic nanoparticles, because magnetic nanoparticles can be readily separated the reaction solutions using magnetic attraction [42,52,53,[64][65][66][67][68]. Nanoscale magnetic particles have a unique property of superparamagnetism [69,70].…”

Abstract:The cost of biodiesel production relies on feedstock cost. Edible oil is unfavorable as a biodiesel feedstock because of its expensive price. Thus, non-edible crop oil, waste oil, and microalgae oil have been considered as alternative resources. Non-edible crop oil and waste cooking oil are more suitable for enzymatic transesterification because they include a large amount of free fatty acids. Recently, enzymes have been integrated with nanomaterials as immobilization carriers. Nanomaterials can increase biocatalytic efficiency. The development of a nano-immobilized enzyme is one of the key factors for cost-effective biodiesel production. This paper presents the technology development of nanomaterials, including nanoparticles (magnetic and non-magnetic), carbon nanotubes, and nanofibers, and their application to the nano-immobilization of biocatalysts. The current status of biodiesel production using a variety of nano-immobilized lipase is also discussed.
