“…They demand an additional system to treat the wash water comprising unreacted chemicals [1]. Biocatalysts exploit the versatility of enzymes to catalyze a variety of processes in the production of novel compounds and natural products [1,2]. Biological catalysts can be divided into three categories: free enzymes, traditionally immobilized enzymes, i.e., non-magnetic materials as carriers, and enzymes immobilized on magnetic nanoparticles.…”

Free enzymes employed as biological catalysts have many advantages such as low reaction time, involving low energy and less waste output when compared to conventional chemical catalysts. However, commercial utilization of free enzymes is often hampered by the lack of operational stability, high cost, and non‐reusability. Immobilization of enzyme is an option to overcome these obstacles. Immobilized enzyme expresses stable performance in organic solvents even in adverse pH, which makes the biomolecules reusable and prosperous as a biological catalyst. Biological catalysis with immobilized enzymes is found to be an alternative method instead of chemical catalysis for chemical reactions in the foreseeable future. Sources of lipase, techniques in immobilization and cross‐linkers are dealt with in this paper.

Carriers used in the immobilization process play a major role in enhancing the properties of the biocatalyst. Polymers are used as organic carriers for enzyme immobilization to improve the thermal, chemical, and operational stability of the enzyme. A variety of carriers are used in the immobilization of enzymes, e.g., mica, silica, zeolites, hydrotalcites, activated carbon, gold and magnetic nanoparticles. Silica‐based carriers offer suitable matrices for enzyme immobilization to manufacture industrial products. Immobilization on nanoparticles has become attractive in biocatalytic applications due to the combination of physical, chemical, catalytic, electronic, and optical properties. Gold nanoparticles also have received attention in the preparation of biocatalysts due to the above‐mentioned reasons. Magnetic nanoparticles are used as a carrier since they can be isolated by an external magnetic field, which is of special interest in the synthesis of organic products such as biodiesel. Different carrier materials involved in the immobilization of enzymes are discussed in this paper.

“…The Fe 3 O 4 magnetic nanoparticles-immobilized lipase showed 1.41-fold enhanced activity, 31-fold enhanced stability, and better tolerance to changes of solution pH compared to the free enzyme [65]. Thangaraj et al [66] examined the effect of various SiO 2 ratios for coating on Fe 3 O 4 and further functionalization of Fe 3 O 4 /SiO 2 magnetic nanoparticles using organosilane compounds (3-aminopropyltriethoxysilane (APTES) and 3-mercaptopropyltrimethoxysilane (MPTMS)) for lipase immobilization. When the Fe 3 O 4 :SiO 2 ratio was 1:0.25, the immobilization efficiency was the highest.…”

“…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.
