“…Moreover, Chlorella accumulate high concentrations of carotenoids (astaxanthin, lutein, β-carotene, violaxanthin and zeaxanthin), antioxidants, vitamins, polysaccharides, proteins, peptides and fatty acids (Mata et al, 2010;Safi et al, 2014). Due to their high lipid content (ranging from 14 to 63% of dry weight), Chlorella is also considered a promising source for biofuel production, which can be grown without competing with human food crops (Caetano et al, 2020a;Frumento et al, 2013;Mata et al, 2016). After lipid transesterification for biodiesel, the residual biomass can be used to produce other biofuels such as methane, bio-oil and ethanol (Sakarika and Kornaros, 2019).…”

“…Botryococcus and Chlorella are suitable microalgae for biodiesel production due to their ability to accumulate high lipid content under stress conditions (Caetano et al, 2020a;Frumento et al, 2013;Martins et al, 2016). In particular, Botryococcus braunii are able to reach a higher lipid content of 65%, containing 9.95%, 79.61% and 10.54% of respectively saturated, monounsaturated and polyunsaturated fatty acids, which makes it suitable for biodiesel production (Tasic et al, 2016).…”

“…The above was mainly attributed to the different metabolic pathways used to assimilate and metabolize carbon under each growth regime [13], as well as the nutrimental characteristics of each residue [3,4]. Although biochemical composition varies among microalga species [3,34] as well as culture conditions [38], the excess carbon and energy of filtered TVs could induce rapid carbohydrate production. This result can be explained because its biosynthesis is energetically lower than lipids 1 3…”

The selection of a suitable growth regime can increase the physiological performance of microalgae and improve bioprocess based on these microorganisms from agro-industrial residues. Thus, this study assessed the biotechnology capacity-biomass production, biochemical composition, and nutrient uptake-from tequila vinasses (TVs) as the nutrient source of three indigenous microalgae-Chlorella sp., Scenedesmus sp., and Chlamydomonas sp.-cultured under heterotrophic and mixotrophic conditions. The results demonstrated that under the mixotrophic regime, the three microalgae evaluated reached the highest nitrogen uptake, biomass production, and cell compound accumulation. Under this condition, Chlorella sp. and Scenedesmus sp. showed the highest nutrient uptake and biomass production, 1.7 ± 0.3 and 1.9 ± 0.3 g L −1 , respectively; however, the biochemical composition, mainly carbohydrates and proteins, varied depending on the microalgal strain and its growth regime. Overall, our results demonstrated the biotechnological capacity of native microalgae from TVs, which may vary not only depending on the microalgal strain but also the culture strategy implemented and the characteristics of the residue used, highlighting-from a perspective of circular bio-economy-the feasibility of implementing microalgal bioprocess to reuse and valorize the nutrimental composition of TVs through biomass and high-valuable metabolite production, depicting a sustainable strategy for tequila agro-industry in Mexico.

“…In this scenario, the integration of processes allows the use of all microalgal biomass, which reduces production costs and generates more sources of revenue, due to the wide spectrum of marketable products that result. 15,16 For these reasons, microalgae biorefineries have increasingly become the subject of research, and compounds produced by microalgal cells, as well as the microalgae themselves, are utilized in several industrial sectors. Furthermore, biocompounds extracted from microalgae can be applied to obtain bioproducts such as biofuels, enabling even the co-products obtained to be reused.…”

Microalgae are a rich source of bioactive compounds such as pigments, carbohydrates, lipids, proteins, and other substances of interest. Thus, given the possible variety of products that can be obtained from them, it is important to determine their biochemical composition, taking into consideration the species and cultivation conditions, so that they can be used as feedstock in biorefineries, with the aim of using all the biomass in the biorefining processes and increasing its economic viability. This work aimed to characterize the biochemical composition of the microalgae Dunalliela salina in a multi‐product biorefinery context, focusing on the production of high value‐added compounds such as pigments and biofuels. The biomass concentration obtained was 1.15 g·L−1 and the volumetric productivity was 164.28 mg·L−1·day−1, providing fractions of 23.86 ± 0.24% of lipids, 10.80 ± 0.86% of carbohydrates, and 5.71 ± 0.50% of proteins. The microalgal biomass contained pigment concentrations of 0.896 and 0.5380 mg·g−1of chlorophylls a and b, and 0.2043 mg·g−1 of total carotenoids. Thus, the data suggest that D. salina has biotechnological potential for application in integrated multi‐product biorefineries, focused on obtaining energy and high added value products simultaneously.
