Sorption is here proposed as a promising approach for metal pre-concentration and recovery from wastewater. A study was carried out on the simultaneous sorption of Co2+, Cu2+, Ni2+ Zn2+ macroalgae, microalgae cyanobacteria. The effect pH, initial concentration, competition time contact were evaluated. Metal hampers at studied concentration ranges. counterion (sulfate, chloride or acetate) did not influence sorption. brown algae Sargassum sp. most sorbent (qmax = 0.66 ± 0.03 mmol·g−1), followed by Phaeodactylum tricornutum 0.36 0.02 mmol·g−1) cyanobacteria Spirulina 0.216 0.007 mmol·g−1). All biomass samples showed preferential Cu2+. experimental kinetic data well described Ho's model, showing chemisorption to be main mechanism. Ion-exchange Ca2+, K+ H+ also played significant role in After sorption, achieved resorting incineration. content obtained biochar 4639-fold higher when compared aqueous solution concentration.

Abstract Extracellular polymers (EPS) produced by microalgae are considered an important factor in the process of biosorption environmental contaminants. The study investigated impact mixotrophic cultivation unicellular algae Chlorella vulgaris , Parachlorella kessleri and Vischeria magna on specific productivity yield total soluble EPS as well biochemical composition sorption properties extracellular order to explore their potential be used for biosorption. results showed that conditions enhanced contributed changes monomer EPS. Higher levels sugars, reducing protein, phenolic compounds reduced content uronic acids were observed isolated conditions. Rhamnose, xylose, mannose, glucose, galactose detected samples.

Cyanobacteria are blue-green Gram-negative and photosynthetic bacteria which seen as one of the most morphologically numerous groups prokaryotes. Because their ability to fix gaseous nitrogen carbon dioxide organic materials, they known play important roles in universal nutrient cycle. has emerged promising resources combat issues global warming, disease outbreaks, nutrition insecurity, energy crises well persistent daily human population increases. possess significant levels macro micronutrient substances facilitate versatile popularity be utilized food protein supplements many countries such Asia. been employed a complementary dietary constituent feed for poultry vitamin supplement aquatic lives. They effectively used deal with tasks various fields biotechnology, agricultural (including aquaculture), industrial (food dairy products), environmental (pollution control), biofuel (bioenergy) pharmaceutical biotechnology (such antimicrobial, anti-inflammatory, immunosuppressant, anticoagulant antitumor); recently, growing interest applying them biocatalysts observed well. generate variety bioactive compounds. However, potential applications cyanobacteria could growth rate survival severe conditions due distinct unique metabolic pathways active defensive mechanisms. In this review, we elaborated on different areas biotechnology. We also emphasized factors that impede implementation execution strategies enhance effective applications.

In recent years, overexplorations of ore and the growth industries are prime factors in release heavy metals environments. As a result, food crops water bodies contaminated with which may have several adverse effects on health humans other living species. These metalloids, such as Zn, Cu, Mn, Ni, Cr, Pb, Cd, As, upset biochemical pathways metabolite synthesis organisms contribute to etiology different diseases. Microorganisms include bacteria, archaea, viruses, many unicellular eukaryotes, can span three domains life—Archaea, Bacteria, Eukarya—and some microorganisms, cyanobacteria, shown high efficiency biosorption rate metals. Cyanobacteria suitable for bioremediation they grow environments, less negative impact surrounding environment, relatively cheaper manage. The structure cyanobacteria has no extensive internal-bound membranes, so it directly employ physiological mechanisms uptake from contamination sites. Such makeups managing bioremediating metal concentrations polluted This review aims explore potential metalloids bodies. Additionally, we identified prospects enhancing effectiveness.

Food safety has occurred as a high-urgency issue for sustainable agricultural production. Heavy metal (HM)/metalloid toxicity in soil and water substantially impacts productivity, which is beyond heightened by intense anthropogenic activities innovative systems, putting food human health at threat. Other than lowering crop production, enhanced HM also distracts plant's needs resource stability. Compensating requires better knowledge of the intricate mechanisms physiological, biochemical, molecular, cellular, plant level that may rise improved productivity. Therefore, plants have set up various internal defense against adverse consequences HMs. Nonetheless, these are insufficient to devastate toxicity. Plants generate numerous secondary messengers activate cell signaling, activating several transcriptional responses connected with defense. Hence, recent improvements omics approaches, instance, genomics, transcriptomics, proteomics, metabolomics, miRNAomics, phenomics, allowed characterization molecular regulators interrelated tolerance. This chapter highlights Further, multi-omics approaches been presented identify stress-related key enhance tolerance plants.

The review article explores the state-of-the-art advancements in using bioreactors based on microalgae to detoxify wastewater, with an emphasis removal of various environmental contaminants (VECs). Because their persistence and capacity for bioaccumulation, these pollutants—which include nutrients, heavy metals, organic compounds, microplastics, Polycyclic Aromatic Hydrocarbons (PAHs), emerging contaminants—pose serious threats environment human health. Innovative solutions are required since traditional wastewater treatment procedures frequently fail efficiently eradicate VECs. carefully looks at how well can break down remove VECs from wastewater. It clarifies numerous processes, including as biosorption, biotransformation, by which aid elimination pollutants. Contaminants be ingested microalgae, then metabolise them into less toxic compounds or incorporate biomass. This study examines adding methods improve both overall effectiveness operational stability. Operational challenges such maintaining optimal growth conditions scalability bioreactor systems, need continuous monitoring control thoroughly discussed. analysis highlights several avenues future research, genetically modifying strains enhance pollutant degradation, creating more effective designs, incorporating cutting-edge systems. indicates that although microalgae-based have great potential VECs, further investigation developments technology needed fully realise this large-scale applications. Researchers, engineers, politicians benefit greatly review, offers a thorough grasp present applications treatment.
