The rapid expansion of both the global economy and human population has led to a shortage water resources suitable for direct consumption. As result, remediation will inexorably become primary focus on scale. Microalgae can be grown in various types wastewaters (WW). They have high potential remove contaminants from effluents industries urban areas. This review focuses recent advances WW through microalgae cultivation. Attention already been paid microalgae-based wastewater treatment (WWT) due its low energy requirements, strong ability thrive under diverse environmental conditions, transform nutrients into high-value compounds. It turned out that WWT is an economical sustainable solution. Moreover, different toxins are removed by biosorption, bioaccumulation, biodegradation processes. Examples agricultural runoffs textile pharmaceutical industrial effluents. mitigate carbon dioxide make use micronutrients present paper highlights application pollutants commonly mechanisms, simultaneous resource recovery, efficient co-culturing systems along with bottlenecks prospects.

The existence of continually increasing concentrations antibiotics in the environment is a serious potential hazard due to their toxicity and persistence. Unfortunately, conventional treatment techniques, such as those utilized wastewater plants, are not efficient for containing antibiotic. Recently, algae-based technologies have been found be sustainable promising technique antibiotic removal. Therefore, this review aims provide critical summary important role treatment. Algal removal mechanisms including bioadsorption, bioaccumulation, biodegradation discussed detail, with using algae-bacteria consortia treatment, integration algae other microorganisms (fungi multiple algal species), hybrid constructed wetlands, factors affecting degradation comprehensively described assessed. In addition, use precursor production biochar highlighted, along modification materials improve its capacity advanced oxidation processes. Furthermore, recent novel approaches enhancing removal, genetic engineering enhance bioelectrochemical systems discussed. Finally, some based on review, key future research perspectives proposed. Overall, systematically presents current progress algae-mediated technologies, providing insights improved alleviation pollution aquatic environments.

The pollution of the aquatic environment has become a worldwide problem. widespread use pesticides, heavy metals and pharmaceuticals through anthropogenic activities increased emission such contaminants into wastewater. Pharmaceuticals constitute significant class can seriously threaten health non-target organisms. No strict legal regulations on consumption release water bodies have been implemented global scale. Different conventional wastewater treatments are not well-designed to remove emerging from with high efficiency. Therefore, particular attention paid phycoremediation technique, which seems be promising choice as low-cost environment-friendly treatment. This technique uses macro- or micro-algae for removal biotransformation pollutants is constantly being developed cope issue contamination. aims this review are: (i) examine occurrence in water, their toxicity organisms describe inefficient treatments; (ii) present cost-efficient algal-based techniques contamination removal; (iii) characterize types algae cultivation systems; (iv) challenges advantages phycoremediation.

Antibiotics, the most frequently prescribed drugs, have been widely applied to prevent or cure human and veterinary diseases undoubtedly led massive releases into sewer networks wastewater treatment systems, a hotspot where occurrence transformation of antibiotic resistance take place. Extracellular polymeric substances (EPS), biopolymers secreted via microbial activity, play an important role in cell adhesion, nutrient retention, toxicity resistance. However, potential roles sludge EPS related removal antibiotics are still unclear. This work summarizes composition physicochemical characteristics state-of-the-art EPS, highlights critical removal, evaluates their defense performances under different exposures, analyzes typical factors that could affect sorption biotransformation behavior antibiotics. Next, interactions between genes analyzed. Future perspectives, especially engineering application for detection defense, also emphatically stressed.

Water is the most valuable resource on planet. However, massive anthropogenic activities generate threatening levels of biological, organic, and inorganic pollutants that are not efficiently removed in conventional wastewater treatment systems. High (carbon, nitrogen, phosphorus), emerging chemical contaminants such as antibiotics, pathogens (namely antibiotic-resistant ones related genes) jeopardize ecosystems human health. Conventional systems entail several environmental issues: (i) high energy consumption; (ii) CO2 emissions; (iii) use chemicals or generation harmful by-products. Hence, microalgal (entailing one microalgae species, consortium with bacteria) agents towards has been seen an environmentally friendly solution to remove pollutants, coliforms antibiotic resistance genes. In recent years, authors have evaluated for different types wastewater, agricultural, municipal, industrial. Generally, can provide removal efficiencies of: up 99%, 90% total phosphorus, and/or organic carbon, respectively, through uptake mechanisms, antibiotics frequently found wastewaters, sulfamethoxazole, ciprofloxacin, trimethoprim azithromycin at 86%, 65%, 42% 93%, desirable mechanism, biodegradation. Although by species complex very strain-specific, it also possible attain coliform Escherichia coli 99.4% 98.6%, respectively. systems' effectiveness strongly relies biotic abiotic conditions, thus selection operational conditions critical. While combination selected (microalgae bacteria), ratios inoculum concentration allow efficient amounts biomass (that be further converted into products biofuels biofertilisers), factors pH, hydraulic retention time, light intensity CO2/O2 supply a crucial role removal, disinfection. some rationale must considered according purpose. alkaline pH induces hydrolysis faecal coliforms, decreases phosphates solubility formation ammonium from ammonia. Also, while increases E. Pseudomonas aeruginosa, well growth (and uptake), Enterococcus faecalis removal. Therefore, this review aims critical studies application pathogens; discussing feasibility, highlighting advantages challenges implementation process, presenting current case-studies applications

Sustainable agriculture practices involve the application of environment-friendly plant growth promoters and additives that do not negatively impact health ecosystem. Stringent regulatory frameworks restricting use synthetic agrochemicals increase in demand for organically grown crops have paved way development novel bio-based promoters. In this context, microalgae biomass derived offer sources promotors enhance crop productivity impart disease resistance. These beneficial effects could be attributed to presence wide range biomolecules such as soluble amino acid (AA), micronutrients, polysaccharides, phytohormones other signaling molecules biomass. addition, their phototrophic nature, high photosynthetic efficiency, environmental adaptability make them an attractive source biostimulants, biofertilizers biopesticides. The present review aims describe various promoting metabolites produced by on productivity. Further, elicited biostimulants with respect different modes applications seed treatments, foliar spray soil/root drenching is reviewed detail. ability tolerance against abiotic biotic stressors along mechanism action discussed paper. Although based gaining popularity, nutrient water requirements energy intensive downstream processes makes technology commercially unsustainable. Addressing challenge, we propose a circular economy model mediated bioremediation coupled biorefinery approaches generating value biofertilizer applications. We discuss new trends enhancing sustainability production co-cultivation algae hydroponics utilization effluents.
