“…Currently both Porphyridium sp. [44] and Skeletonema sp. [45] are acknowledged as Generally Recognized as Safe by the Food and Drug Administration and are also being investigated as bioremediation agents of heavy metals (copper, cadmium, iron, among others), due to their affinity towards metal ions.…”

Microalgae are an untapped source of bioactive compounds with various biotechnological applications. Several species are industrially produced and commercialized for the feed or cosmetic industries, however, other applications in the functional food and pharmaceutical markets can be foreseen. In this study, nine industrial/commercial species were evaluated for in vitro antioxidant, calcium-chelating, anti-tumoral, and anti-inflammatory activities. The most promising extracts were fractionated yielding several promising fractions namely, of Tetraselmis striata CTP4 with anti-inflammatory activity (99.0 ± 0.8% reduction in TNF-α production in LPS stimulated human macrophages at 50 µg/mL), of Phaeodactylum Tricornutum with cytotoxicity towards cancerous cell lines (IC50 = 22.3 ± 1.8 μg/mL and 27.5 ± 1.6 μg/mL for THP-1 and HepG2, respectively) and of Porphyridium sp. and Skeletonema sp. with good chelating activity for iron, copper and calcium (IC50 = 0.047, 0.272, 0.0663 mg/mL and IC50 = 0.055, 0.240, 0.0850 mg/mL, respectively). These fractions were chemically characterized by GC–MS after derivatization and in all, fatty acids at various degrees of unsaturation were the most abundant compounds. Some of the species under study proved to be potentially valuable sources of antioxidant, metal chelators, anti-tumoral and anti-inflammatory compounds with possible application in the functional food and pharmaceutical industries.

“…Biosorption is the fast passive adsorption outside the cell, while bioaccumulation is an active and slow transport process. Microalgal cell wall components include organic proteins, polysaccharides, lipids as well as cellular macromolecules such as peptides and exopolysaccharides, with various functional groups to bind heavy metals (Priatni et al, 2018). Moreover, laminar, carboxyl, monomeric alcohol and deodorizing sulfates of macromolecular clusters from microalgae can also be formed to attract cations and anions of different heavy metals (Pradhan et al, 2019;Leong and Chang., 2020).…”

Soil is the basis of agricultural production, and the quality of soil directly affects crop quality and yield. Microalgae can carry out photosynthesis, carbon and nitrogen fixation, and produce large amounts of valuable biomass coupled with wastewater treatment. Also, microalgae can produce plant hormones and other high-value products, which can promote plant growth, improve soil fertility, soil ecological health, and control crop diseases. This research reviews the characteristics of microalgae in improving soil health, discusses the situation of microalgae in controlling soil pollutants, elaborates on the technical application of microalgae in alleviating soil problems, and proposes potential applications of microalgae in ecological environment. Also, resource utilization of multifunctional microalgae is discussed, to provide a theoretical basis for the application of microalgae in soil improvement.

“…The microalgae species are based on various approaches, including distinct and unique self-respect processes to prevent systemic toxicity, such as gene management, exclusion and chelation, heavy metal immobilization, and phytonutrients, or chemical reactions to reduce toxic heavy metals [87]. Without changing its course of action, cyanobacteria can even form microbial protein compounds [88].…”

“…The first step is accelerated passive outer membrane adsorption (biosorption), whereas the second is delayed positive diffusion and aggregation of intracellular substances (bioaccumulation), and the third is biotransformation by various reactions such as redox potential, ROS, methylation. Apart from polymeric cell materials such as proteins and exopolysaccharides, which have uronic groups, algal cells are made primarily of the polysaccharides, lipids, and natural proteins which are responsible for binding toxic substances (hydroxylic, sulfonate, thiol, imidazole, amino, carboxylic, phosphate and others) [88].…”

Microalgae have been publicized for their diversified dominance responsiveness and bioaccumulation potential toward pollutants in an ecosystem. Also, algal's incredible capability as biocatalysts in environmental appliances has been well elucidated owing to their robustness and simple nutritional demand. Additionally, microalgae can deliver various collections of bio-based chemical compounds helpful for diversified applications, especially as green alternatives. The environment has been contaminated with various polluting agents; one principal polluting agent is heavy metals which are carcinogenic and show toxicity even in minimal quantity, cause unsatisfactory threats to the environmental ecosystem, including human and animal health. There is a prominent tendency to apply microalgae in the phytoremediation of heavy metals compounds because of its vast benefits, including great accessibility, cost-effective, excellent toxic metal eliminating efficiency, and nontoxic to the ecosystem. This review uncovers the most recent advancements and mechanisms associated with the bioremediation process and biosorption interaction of substantial harmful synthetic compounds processing microalgae species. Furthermore, future challenges and prospects in the utilization of microalgae in heavy metals bioremediation are also explored. The current review aims to give valuable information to aid the advancement of robust and proficient future microalgae-based heavy metal bioremediation innovations and summarizing a wide range of benefits socioeconomic scope to be employed in heavy metal compound removal in environment system.
