“…their ability to perform photoautotrophic, mixotrophic, or heterotrophic metabolism , they represent promising biological systems for treating a variety of sources of wastewater. In particular, in the context of a circular and bio‐based economy and the development of biorefinery concepts , microalgae biomass produced from wastewater streams offers a great potential for sustainable bioproducts (dependent on national legislation on reusing microalgae biomass/bioproducts), such as proteins , fatty acids , pigments , biofertilizers/biochar , and animal feed . Algae‐based WWT technologies have in fact been researched since the 1950s, mainly because of their very efficient fixation of inorganic N and P.…”

Current global environmental issues raise unavoidable challenges for our use of natural resources. Supplying the human population with clean water is becoming a global problem. Numerous organic and inorganic impurities in municipal, industrial, and agricultural waters, ranging from microplastics to high nutrient loads and heavy metals, endanger our nutrition and health. The development of efficient wastewater treatment technologies and circular economic approaches is thus becoming increasingly important. The biomass production of microalgae using industrial wastewater offers the possibility of recycling industrial residues to create new sources of raw materials for energy and material use. This review discusses algae‐based wastewater treatment technologies with a special focus on industrial wastewater sources, the potential of non‐conventional extremophilic (thermophilic, acidophilic, and psychrophilic) microalgae, and industrial algae‐wastewater treatment concepts that have already been put into practice.

“…Natural pigments have an important role in the photosynthetic metabolism and pigmentation in algae, and may also have beneficial biological activities, such as antioxidant, anticancer, anti‐inflammatory, anti‐obesity, antiangiogenic, and neuroprotective (D'Alessandro and Antoniosi Filho ). As a result of thriving in such diverse and extreme environments, they produce an array of unique bioactive, complex, exotic acyl lipids and fatty acids that are not generally present in terrestrial plants (Kumari et al.…”

“…The enzymes involved in lipid metabolism may be significantly altered by gene expression levels, since they depend on environmental conditions (D'Alessandro and Antoniosi Filho ). The use of extremophiles/extremozymes helps to broaden the range of operating conditions and to overcome the limitations of traditional bioprocesses (Rathinam and Sani ).…”

Microalgae are photosynthetic microorganisms that use sunlight as an energy source, and convert water, carbon dioxide, and inorganic salts into algal biomass. The isolation and selection of microalgae, which allow one to obtain large amounts of biomass and valuable compounds, is a prerequisite for their successful industrial production. This work provides an overview of extremophile algae, where their ability to grow under harsh conditions and the corresponding accumulation of metabolites are addressed. Emphasis is placed on the high‐value products of some prominent algae. Moreover, the most recent applications of these microorganisms and their potential exploitation in the context of astrobiology are taken into account.

“…Thylakoids are rich in protein but have membranes dominated by lipids (Simionato et al 2013). Other components of microalgae chloroplast include photosynthetic pigments, chlorophyll a and chlorophyll b, and carotenoids α-and β-carotene and xanthophylls such as astaxanthin, lutein, zeaxanthin, and neoxanthin (Gong and Bassi 2016;D' Alessandro and Filho 2016).…”

Microalgae biomass has garnered significant attention as a renewable energy feedstock and alternative to petroleumbased fuels. The diverse metabolism of green microalgae species additionally provides opportunities for recovery of products for feed, food, nutraceutical, cosmetic, and biopharmaceutical industries. Recently, the concept of using microalgae as part of a biorefinery model has been adopted in place of refinery methods focused on recovering one target product. This has led to producers exploring co-production of high value and high volume products in an effort to improve process economics. With numerous potential products and applications, the biomass source or specific strain must be carefully selected to accumulate extractable levels of the target molecule(s). It is additionally imperative to understand the morphology and metabolism of the selected strain to cost-effectively manage all stages of commercial production. This review will focus specifically on microalgae in the division of Chlorophyta, or green algae and their extracellular matrices (ECM), potential for commercial products, and finally describe a holistic approach for biomolecule extraction and recovery. Additionally, cell disruption and fractionation methods for recovery of biomolecules for commercial products are highlighted along with an alternative method, aqueous enzymatic processing for multiple biomolecule extraction and recovery from green microalgae. An emphasis is placed on connecting the morphological characteristics of microalgae ECM or organelle membranes to implications on separation and purification technologies.
