“…For typical biodiesel productions, one key step is to use transesterification of fat molecules (from animal, vegetable or waste fat) to form long‐chain esters and glycerol, followed by a decarboxylation of esters, as examples of two‐step cascades. Enzymes, notably lipases, have been widely used as catalysts for this transesterification reaction 16 . Decarboxylation of fatty acids to form hydrocarbons also may be carried out using other enzymes 17 .…”

In recent years, energy and environmental issues have become more topical as the public have become more conscious about the fragility of the planet we live in. Biocatalysis can have a strong impact on these issues as most enzymes are operated at low energy and solvent‐free environments with often high conversion, activity and selectivity. Enzymatic cascades are multistep reactions that can produce more complex chemical products and mimic in vivo reactions in nature. Therefore, they can provide valuable solutions for many environmental problems. However, enzymes can be expensive, difficult to recycle and wasteful, as seen in other homogeneous systems. For heterogenized biocatalytic systems, enzyme immobilization has been considered to enhance reuse and recycling of enzymes but immobilized enzymes are still underdeveloped for use in cascade systems. Hence, there is an opportunity for advancement. The difficulties for implementing immobilized enzymes in cascades mainly concern enzyme compatibility, compartmentalization and optimization. In this perspective, we have highlighted key examples in using enzymatic cascades using immobilized enzymes, in particular those systems related to the energy and environment sectors. We also demonstrate use of a combination of a magnetic and a nonmagnetic support for enhancing enzyme reuse and recycling in a cascade system, and more importantly, separation of enzymes from each other postreaction. We can foresee that, with significant effort spent on the development, enzyme immobilization could play a significant role in cascades for the green synthesis of fine chemicals. © 2024 The Authors.

“…Immobilized lipase plays a significant role in biodiesel production and various processes are optimized for this purpose. Microbial lipases are frequently used for biodiesel production and the choice of the lipases depends on their origin and formulation [ 58 , 144 , 145 ]. The important aspects of microbial lipases include their high activity, short reaction time, lower production inhibition, thermal tolerance, and the reusability of immobilized enzymes [ 146 ].…”

Lipases are versatile biocatalysts and are used in different bioconversion reactions. Microbial lipases are currently attracting a great amount of attention due to the rapid advancement of enzyme technology and its practical application in a variety of industrial processes. The current review provides updated information on the different sources of microbial lipases, such as fungi, bacteria, and yeast, their classical and modern purification techniques, including precipitation and chromatographic separation, the immunopurification technique, the reversed micellar system, aqueous two-phase system (ATPS), aqueous two-phase flotation (ATPF), and the use of microbial lipases in different industries, e.g., the food, textile, leather, cosmetics, paper, and detergent industries. Furthermore, the article provides a critical analysis of lipase-producing microbes, distinguished from the previously published reviews, and illustrates the use of lipases in biosensors, biodiesel production, and tea processing, and their role in bioremediation and racemization.

“…In most cases, lipases are invented from microorganisms such as Burkholderia cepacia, Thermomyces lanuginosus, Candida antarctica, Aspergillus niger, Anoxybacillus gonensins etc. During fermentation under specially monitored conditions (Toldrá-Reig et al, 2020;Altinok et al, 2023). Lipases are subdivided into intracellular lipases and extracellular lipases.…”

The search for renewable, affordable, sustainable, and ecologically benign fuels to substitute fossil-based diesel fuels has led to increased traction in the search for biodiesel production and utilization in recent times. Biodiesel, a form of liquid biofuel, has been found to alleviate environmental degradation, enhance engine performance, and reduce emissions of toxic gases in transportation and other internal combustion engines. However, biodiesel production processes have been dogged with various challenges and complexities which have limited its expected progression. The introduction of data-based technologies is one of the remedies aimed at deescalating the challenges associated with biodiesel synthesis. In this study, the application of machine learning (ML) –based technologies including artificial neural network (ANN), response surface methodology (RSM), adaptive network-based fuzzy inference system (ANFIS), etc. As tools for the prediction, modeling, and optimization of the biodiesel production process was interrogated based on the outcomes of previous studies in the research domain. Specifically, we review the influence of input variables like alcohol: oil molar ratio, catalyst concentration, reaction temperature, residence time, and agitation speed on the biodiesel yield (output variable). The outcome of this investigation shows that the usage of ANN, RSM, ANFIS, and other machine learning technologies raised biodiesel yield to between 84% and 98% while the statistical verification shows that the Pearson correlation coefficient and coefficient of determination are close to 1. Going forward, more targeted and collaborative research is needed to escalate the use of innovative technologies for the entire biodiesel value chain to enhance production efficiency, ensure economic feasibility, and promote sustainability.
