“…The result showed that all the species able to remove COD (98%), inorganic nitrogen (94%), and phosphate (100%). Furthermore, some cyanobacterial strains are also able to remediate different types of wastewaters and subsequently help in wastewater recycling and produced biomass utilized for the production of biofuels and high‐value bioproducts (Khan et al., 2021; Shahid, Malik, Liu, et al., 2020). For example, Shahid, Usman, et al.…”

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.

“…This ensures the products were obtained within a stipulated time frame and in a cost-efficient fashion thereby improving the economic feasibility of products. Some of the reasons that prevent huge capital investments on microalgae include selection and isolation of the strain, nutrient source and their utilization, higher cost of cultivation, production management, downstream processing, extraction of valueadded products, refining and biomass reutilization, and more importantly marketing and sale price [28]. The wide taxonomic and genetic diversity of microalgae paved way for genetic modifications and redesigning, pertaining to biofuel production and desired metabolite synthesis.…”

Microalgae are complex metabolic machineries whose potential has been continuously tapped for wide range of applications. Their suboptimal biomass yield and bioactives production remain the mainstay for their commercialization. To surpass the limitations, genetic engineering and its decisive role in strain improvement have led to the enhancement of quality and yield of products. Meanwhile, the sporadic use of genetic engineering tools specifically toward microalgal strains has limited their applicability. In this context, this article was mainly prepared to highlight the characteristics of microalgae and the introduction of omics approach for the improvement of strain for biorefinery processes. Furthermore, genome editing and gene-interfering tools to augment algal research using reference strains have been described. The progress made by genetic engineering in editing a gene using CRISPR-Cas9 and metabolic engineering of microalgae for biofuel production and CO 2 sequestration have been critically reviewed. As a futuristic alternative, the transgenic microalgae would compete with the existing resources reducing the dependency on fossil fuel in terms of cost, energy production, and efficacy.

Microalgae and cyanobacteria have sparked a lot of interest due to their potential in various industries like biorefineries, biopharmaceuticals, food supplements, nutraceuticals, and other high‐value products. Polysaccharides, vitamins, proteins, enzymes, and steroids are valuable products isolated from microalgae and cyanobacteria and potentially used in health and biomedical applications. Bioactive compounds derived from microalgae and cyanobacteria exhibit various pharmaceutical properties like antibacterial, anticancer, antiviral, antialgal, and antioxidant. From the properties listed above, the research for novel antibiotics has become particularly appropriate. In addition, the possible emergence of resistance against pathogens, as well as the potential decline in antibiotic efficacy, has prompted researchers to look for a new source of antibiotics. Microalgae and cyanobacteria have indicated a great and unexplored potential among these sources. For this reason, microalgae and cyanobacteria have been highlighted for their efficiency in different industrial sectors, as well as for their potential uses in the betterment of human and environmental health. This review gives an overview of bioactive compounds and metabolites with several biological properties isolated from microalgae and cyanobacteria for treating different animal and human diseases.
