“…However, this process inherent several drawbacks related to high energy consumption, nonenvironmental friendly reaction, nonbiodegradable catalyst, and harmful by-products and wastes [i.e., acids and heavy metals (Pd, Fe, Cd, Mn, and Zn)] [ 78 ]. Therefore, lipases in their heavy metals (Pd, Cd, Fe, Zn, and Mn) form have been implemented to catalyze process for biodiesel production which is environmental friendly (i.e., less hazardous chemicals, lipases reusability, high substrate specificity, less by-products, and lipases biodegradability) and cost-effective (i.e., single step bioconversion of free fatty acids and triglycerides to biodiesel, low substrate molar ratio, less impurities, ease product separation, and recovery) [ 79 , 80 ]. The discovery of TA lipases with high catalytic activity at high temperature (thermostable) and resistance to various environmental factors inhibition are an advantage for a cost-effective enzymatic process [ 23 , 34 ].…”

“…DHE 5, and Antrodia cinnamomea BCRC 35396 have been reported [ 11 , 20 , 29 , 33 , 57 ]. Most of TA producing strains were isolated from several places like desert ecosystem, hot spring, oil-contaminated soil, soil samples of olive oil mill, mushroom spring, alkaline hot spring, pulp and paper mill effluent sludge, alkaline lake, and soil of slaughter house [ 6 , 39 , 80 ]. Table 3 summarized the wild-type (WT) strain of TA lipases.…”

For decades, microbial lipases are notably used as biocatalysts and efficiently catalyze various processes in many important industries. Biocatalysts are less corrosive to industrial equipment and due to their substrate specificity and regioselectivity they produced less harmful waste which promotes environmental sustainability. At present, thermostable and alkaline tolerant lipases have gained enormous interest as biocatalyst due to their stability and robustness under high temperature and alkaline environment operation. Several characteristics of the thermostable and alkaline tolerant lipases are discussed. Their molecular weight and resistance towards a range of temperature, pH, metal, and surfactants are compared. Their industrial applications in biodiesel, biodetergents, biodegreasing, and other types of bioconversions are also described. This review also discusses the advance of fermentation process for thermostable and alkaline tolerant lipases production focusing on the process development in microorganism selection and strain improvement, culture medium optimization via several optimization techniques (i.e., one-factor-at-a-time, surface response methodology, and artificial neural network), and other fermentation parameters (i.e., inoculums size, temperature, pH, agitation rate, dissolved oxygen tension (DOT), and aeration rate). Two common fermentation techniques for thermostable and alkaline tolerant lipases production which are solid-state and submerged fermentation methods are compared and discussed. Recent optimization approaches using evolutionary algorithms (i.e., Genetic Algorithm, Differential Evolution, and Particle Swarm Optimization) are also highlighted in this article.

Biodiesel produced from non-edible plant sources is cost-effective, biodegradable, environment friendly, and compatible with petro-diesel, but new sources and extraction processes still need to be discovered. Here, we explored the fuel properties of seeds from six non-edible plant sources, including Sapindus mukorossi (Soapnut, SP), Vernicia fordii (Tung, TO), Ricinus communis (Castor, CA), Toona sinensis (Juss. TS), Ailanthus altissima (Heaven tree, AA), and Linum usitatissimum L. (Lin seed, LS) from China. The optimum extraction conditions were obtained by optimizing the most important variables (reaction temperature, ratio of alcohol to vegetable oil, catalyst, mixing intensity, and purity of reactants) that influence the transesterification reaction of the biodiesel. All six plants contained high seed oil content (SOC; % w/v) with the highest in the TO-54.4% followed by SP-51%, CA-48%, LS-45%, AA-38%, and TS-35%, respectively, and all expressed satisfactory physico-chemical properties as per international standards of ASTM D6751 and EN14214. Our data provide a scientific basis for growing these plants in unproductive agricultural lands as an alternative energy sources for biodiesel production either standalone or blended with petro-diesel.

“…Besides the content of fuel in the oil phase, the mass transfer 44 in between phases plays a key role in tuning the lifetime of MSP. Factors that may affect the efficiency of mass transfer such as the volume of water phase, the stirring rate, and the temperature were evaluated while the content of Mg(ClO 4 ) 2 remained constant.…”
