“…Owing to their significance in the element elimination experiment, trace metals were used in the final medium at the original concentration instead of being removed. Essentially, trace metals are essential components for cell growth [ 16 ]. The Tris base, NH 4 Cl, MgSO 4 , and AcOH had negative effects, whereas CaCl 2 and potassium phosphate had positive effects ( Table 1 ).…”

Polar microorganisms produce biologically active compounds that enable them to survive in harsh environments. These compounds have potential biomedical applications. The green microalga Chlamydomonas latifrons KNF0041, isolated from Arctic sea ice, has been found to produce polyunsaturated fatty acids (PUFAs), including omega-3 and omega-6, which have antioxidant properties. To improve the biomass production of strain KNF0041, statistical methods such as the Plackett–Burman design, Box–Behnken design, and response surface methodology (RSM) were utilized for medium optimization. The optimized medium was designed with increased potassium phosphate content and reduced acetic acid (AcOH) content. The use of the optimized medium resulted in an increase in the cell number as biomass of strain KNF0041 by 34.18% and the omega-3 and omega-6 fatty acid (FA) content by 10.04% and 58.29%, respectively, compared to that in normal TAP medium, which is known as the growth medium for Chlamydomonas culture. In this study, Chlamydomonas latifrons was discovered for the first time in the polar region and identified using morphology and molecular phylogenetic analyses, the secondary structures of the internal transcribed spacers, and optimized culture conditions. The results of this study provide an efficient method for the application of polar microalgae for the production of bioactive compounds.

“…Regarding other potential biotechnological applications, it is important to highlight the results obtained by the research group concerning its tolerance and potential use in heavy metal contamination remediation. The strain has shown high removal efficiency of Cu 2+ , Fe 3+ , and Mn 2+ as well as its potential as a bioabsorbent to remove Zn 2+ from industrial effluents [17,85].…”

The wide rocky coastline of the Antofagasta hosts an intertidal ecosystem in which the species that inhabit it are routinely exposed to a wide range of physical and chemical conditions and have therefore evolved to tolerate extremes. In the search for new species of potential biotechnological interest with adaptations to a wide range of environmental conditions, the isolation and characterization of microalgae from these ecosystems is of great interest. Here, a new microalgal strain, Tetraselmis marina AC16-MESO, is described, which was isolated from a biofilm collected on the intertidal rocks of the Antofagasta coast (23°36′57.2″ S, 70°23′33.8″ W). In addition to the morphological characterization, 18S and ITS sequence as well as ITS-2 secondary structure analysis revealed an identity of 99.76% and 100% with the species Tetraselmis marina, respectively. The analyses of the culture characteristics and biochemical content showed similarities with other strains that are frequently used in aquaculture, such as the species Tetraselmis suecica. In addition, it is tolerant of a wide range of salinities, thus allowing its culture in water of varying quality. On the other hand, added to these characteristics, the results of the improvement of the lipid content in stressful situations of salinity observed in this study, together with other antecedents such as the potential in bioremediation already published for this strain by the same research group, present a clear example of its biotechnological plasticity. It is noteworthy that this strain, due to its characteristics, allows easy collection of its biomass by decantation and, therefore, a more cost-efficient harvesting than for other microalgal strains. Therefore, this new strain of Tetraselmis marina, first report of this species in Chile, and its morphologically, molecularly and biochemically description, presents promising characteristics for its use in biotechnology and as feed for aquaculture.

The widespread problem of water pollution is jeopardizing the ecosystem and our health. The contamination of freshwater through anthropogenic activities and its discharge into the ecosystems leads to the generation of wastewater. Wastewater mainly contains nutrient loads and the recent emerging contaminants such as pharmaceutical wastes, drugs, micropollutants, heavy metals, pesticides, phenolic compounds, and dyes have increased and contaminated the aquatic bodies. The existence of these emerging pollutants can cause serious threats to ecosystems and humans. Thus, conventional wastewater treatment was focused on the removal of solid compounds or nutrient loads. However, it could not remove the emerging contaminants and later microalgae that are photosynthetic eukaryotic microorganisms were found to be an efficient and eco‐friendly source for the remediation of diverse kinds of wastewater. Apart from nutrient removal, the algal biomass acts as the efficient feedstock for the generation of bioenergy products. However, limited data have been published regarding the remediation of emerging pollutants through microalgae. Thus, focusing on the recent gaps, the current review provides an overview of the potential of microalgae for the remediation of nutrient loads. Critically deliberate the recent advances and detailed summary of microalgae potential for the remediation of wastewaters containing high nutrient loads especially focused on the remediation of different emerging contaminants. It highlights the advanced approaches used in the microalgae remediation process and provides comprehensive information about the different bioenergy products such as liquid, gaseous, and bioelectricity generated through the utilization of wastewater‐grown microalgae.
