“…The key characteristics of biodiesel were examined using the Biodiesel analyzer V 1.1 software (http://www.brteam.ir/biodieselanalyzer) [26] (accessed on 19 April 2023), including cetane number (CN), iodine value (IV), degree of unsaturation (DU), saponification value (SV), kinematic viscosity (KV), oxidative stability (OS), content of saturated fatty acids (SFA), and higher heating value (HHV). This software has been used to estimate the properties of biodiesel made from a microalgae and yeast co-culture [27].…”

Cell wall disturbance is an important step in the downstream process of improving the efficiency of lipid extraction from microalgae. Surfactants have been proven to be efficient alternatives to organic solvents in the extraction process. In this study, an effective approach involving deep eutectic solvent (DES) (choline chloride and carboxylic acids) treatment supplemented with surfactants has been developed to disrupt the cell walls of microalgae and increase the extraction of lipids suitable for biodiesel production. A combination of polar and non-polar solvents (ethyl acetate and n-butanol) was used for the lipid extraction process. Microalgae biomass pretreated with choline chloride malonic acid supplemented with the surfactant hexadecyl trimethylammonium chloride (HTAC) showed the best results, improving lipid extraction by 12.365%. Further elucidation of the detailed mechanism behind the cell disruption of the microalga wall by DES was achieved using density functional theory (DFT) methods. The DFT calculations revealed that hydrogen bonds between the chloride ion of the DES and hydrogen bond donor (HBD) molecules are key factors dominating the destruction of the cell wall structure of Chlorella pyrenoidosa. The optimization of lipid extraction was performed through a single-factor experiment, which included the effects of different variables (time, temperature, dosage of surfactant, and ratio of n-butanol to ethyl acetate). An extraction period of 60 min at 80 °C with a surfactant concentration of 0.5% at a 1:2 ratio of n-butanol to ethyl acetate was found to produce the maximum lipid yield (16.97%). Transesterification reactions were used to obtain fatty acid methyl esters from the optimized extracted lipids. Thus, it was determined that C16:0 (20.04%), C18:2 (29.95%), and C18:3 (21.21%) were the most prevalent fatty acids. The potential for producing biodiesel from C. pyrenoidosa was validated by the high yields of C18 fatty acid methyl esters, and the properties of biodiesel are within the European and US standards.

“…The composition of the biomass and the conditions of the technology to be used play important roles in increasing the production of the energy product of interest. For example, for the production of biodiesel, biomass with a high lipid content must be obtained, and this can be achieved by modifying factors such as temperature, lighting, pH, CO 2 supply, and the number of nutrients in the culture medium [ 45 , 46 , 47 ]. Anh [ 48 ] reported that a concentration of 401.5 ± 47.3 mg/L of fatty acids can be obtained for Nephroselmis sp., and the biodiesel obtained from this strain can reach cetane index values of 52.31, indicating that this biomass can be considered for the production potential of biodiesel.…”

Trends on CO2 Capture with Microalgae: A Bibliometric Analysis

The alarming levels of carbon dioxide (CO2) are an environmental problem that affects the economic growth of the world. CO2 emissions represent penalties and restrictions due to the high carbon footprint. Therefore, sustainable strategies are required to reduce the negative impact that occurs. Among the potential systems for CO2 capture are microalgae. These are defined as photosynthetic microorganisms that use CO2 and sunlight to obtain oxygen (O2) and generate value-added products such as biofuels, among others. Despite the advantages that microalgae may present, there are still technical–economic challenges that limit industrial-scale commercialization and the use of biomass in the production of added-value compounds. Therefore, this study reviews the current state of research on CO2 capture with microalgae, for which bibliometric analysis was used to establish the trends of the subject in terms of scientometric parameters. Technological advances in the use of microalgal biomass were also identified. Additionally, it was possible to establish the different cooperation networks between countries, which showed interactions in the search to reduce CO2 concentrations through microalgae.
