“…Finally, in Acutodesmus obliquus, the bulk of fatty acids were oleic (18:1n-9), palmitic (16:0), linoleic (18:2n-6) and α-linolenic (18:3n-3) acids, which constituted 87.99% and 89.80% of the total FAME in +N and −N conditions, respectively. Our results agree with multiple previously-published reports in that fatty acids with a length of sixteen (C16) and eighteen (C18) carbon atoms are very frequent in many green microalgae species [45,46,[48][49][50]55]. It is notable that under nitrogen starvation culture, all microalgae strains showed an increase in monounsaturated fatty acids (MUFA) from 7.3% in Ankistrodesmus sp.…”

“…Considering the SFA and unsaturated fatty acids (UFA) components, approximately 20%-31% are SFA and 69%-80% are UFA. Hence, the SFA/UFA ratio in the microalgae strains evaluated ranges between 0.25 and 0.45, which is similar to the reports of several microalgae species isolated in different latitudes worldwide [20,31,48,49,70,72]. It is important to highlight that the fatty acid profile determination is an essential step in the process of the characterization of microalgae strains, because it ultimately affects the quality of the biodiesel product [84,85].…”

“…strain NAN001). These percentage values in total lipid content are similar to several microalgae species of these genera isolated and characterized by other researchers worldwide [20,45,46,[48][49][50]57]. Furthermore, it is important to emphasize that lipid content is dependent on the different growth phases.…”

“…Overall, the identification of native microalgae strains presented a good correspondence between morphological characters and sequence-based phylogenetic analysis. Microalgae species of these genera were also isolated from different countries of the world, such as Brazil [47], Argentina [46], United States [48], India [20], Egypt [49], Taiwan [50], South Korea [45] and China [51]. Some of these microalgae genera, such as Ankistrodesmus, Chlorella, Desmodesmus and Scenedesmus, were used in large-scale biodiesel production using photobioreactors and raceway pond systems [52,53].…”

“…In accordance with these reports, Li et al [69] showed that nitrogen deficiency induced, in the green microalgae Micractinium pusillum, a downregulation in the expression of genes involved in cell growth and cell cycle regulation. Additionally, differences in growth profile and specific growth rates are dependent on several factors, such as microalgae genotypes, the culture medium composition, pH, nutrients concentration, the cell culture phase (i.e., log phase, stationary phase) and environmental factors [45,49,54,57,[70][71][72]. …”

Biodiesel production from microalgae triacylglycerols is growing, because this feedstock is a more sustainable and advantageous alternative. In this study, we isolated and identified fourteen strains of native microalgae from the Peruvian Amazon. These strains showed great heterogeneity in biomass productivity, lipid productivity and lipid content, and thus, three of them (Acutodesmus obliquus, Ankistrodesmus sp. and Chlorella lewinii) were selected for further evaluation under culture of nitrogen-sufficient (+N) and nitrogen-deficient (−N) Chu medium No. 10. These microalgae species showed modifications in biomolecule content (protein, lipid and carbohydrate) with a pronounced increase of lipids and carbohydrate and a decrease of protein content under stress culture. Furthermore, the fatty acid profile was peculiar for each species, and these patterns showed evident changes, particularly in the proportion of saturated and monounsaturated fatty acids. The results of this research suggest that the isolated native microalgae, from the Peruvian Amazon, could be suitable candidates for biodiesel production.

The search for clean technologies needs to be continued to offer alternatives for achieving sustainable energy production and a sustainable economy. This concern is particularly related to the demands of both producing enough renewable energy to meet future needs and reducing greenhouse gas (GHG) emissions. Microalgae are recognized for several benefits they offer, and in recent years, the use of life cycle assessment (LCA) to evaluate the benefits resulting from microalgae cultivation, harvesting/dewatering, biomass drying, extraction, and byproduct development has stimulated research in this area. Considering the importance of microalgae and clean technologies and the increasing number of publications on these subjects, this review aims to perform bibliometric mapping of such studies from 2008 to 2018. Web of Science and Scopus databases are used to identify leading trends. Visualization of similarities viewer (VOSviewer) software is applied to analyze the interactions among keywords. The results of this study indicate an association of microalgae and clean technologies and demonstrate that LCA is one of the most common tools used for such analyses. Bibliometric mapping provides relevant data to reinforce this association and understand the main bottlenecks that must be overcome in this field for future progress to be made.

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.
