“…However, these problems can be overcome by immobilizing the enzyme onto different types of support materials. 408 The commonly adopted immobilization methods for biological processes include entrapment, adsorption and covalent bonding. Among these techniques, the entrapment method was found to be effective, offering greater advantages, such as ease of process scale-up, higher stability of the enzyme, and longer enzymatic activity retention.…”

<p>An ever-increasing energy demand and environmental problems associated with exhaustible fossil fuels have led to the search for an alternative renewable source of energy. In this context, biodiesel has attracted attention worldwide as an alternative to fossil fuel for being renewable, non-toxic, biodegradable, carbon-neutral; hence eco-friendly. Despite homogeneous catalyst has its own merits, currently, much attention has been paid to chemically synthesize heterogeneous catalysts for biodiesel production as it can be tuned as per specific requirement, easily recovered, thus enhance reusability. Recently, biomass-derived heterogeneous catalysts have risen to the forefront of biodiesel productions because of their sustainable, economical and eco-friendly nature. Further, nano and bifunctional catalysts have emerged as a powerful catalyst largely due to their high surface area and potential to convert free fatty acids and triglycerides to biodiesel, respectively. This review highlighted the latest synthesis routes of various types of catalysts including acidic, basic, bifunctional and nanocatalysts derived from different chemicals as well as biomass. In addition, the impacts of different methods of preparation of catalysts on the yield of biodiesel are also discussed in details.</p>

“…The alcohol concentration should also be in excess to drive the transesterification reaction towards the desired products, e.g., FAME (Brahma et al, 2022). Moreover, vigorous stirring is required due the immiscibility of fats and oils with methanol, and when there is high content of free fatty acids (FFA) in the feedstock, soap is formed with the alkaline catalyst, hurdling downstream processing; thus, increasing the cost (Kumar et al, 2018). Similarly, the acidic catalysts (Vasić et al, 2020) yield low reaction conversions, the reaction time is longer, they only work under high temperatures (> 100 °C), while they still require alcohol excess (Monteiro et al, 2021;Barbosa et al, 2022).…”

Biodiesel is synthesized by the transesterification of triglycerides of oils with short-chain alcohols, such as methanol and ethanol. According to the Renewable Energy Directive guidelines (RED II 2018/2001/EU) the contribution of advanced biofuels, which do not include edible oils, towards the overall EU target, is at 1% in 2025 and at least 3.5% in 2030. Bioprocesses that valorize non-edible oils for the production of second-generation biodiesel could play a critical role in achieving this goal. Immobilized lipases, as well as other enzyme classes, such as cutinases and acyltransferases, are utilized as biocatalysts for this process. For the sustainability of the process, renewable materials can be used as immobilization matrices, or even enzymes anchored on the cells as whole-cell biocatalysts. Membrane reactors can also be employed to facilitate the enzymatic transesterification by conducting a continuous enzymatic reaction and simultaneously separate the products in a single operation. The advances on the aforementioned fast-pacing fields are presented in this work.

Characterization and compositional analysis of highly acidic karanja oil and its potential feedstock for enzymatic synthesis of biodiesel

Abstract: In the present study, we focused on the synthesis of biodiesel fromPseudomonas cepacia, crude karanja oil by the process of enzymatic transesterification using bio-support materials, such as lipase immobilized on polyvinyl alcohol/AlgNa.
