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.

Microalgae-based livestock wastewater treatment (MbWT) as a circular bioeconomy approach: Enhancement of biomass productivity, pollutant removal and high-value compound production

Journal of Environmental Management, Год журнала: 2022, Номер 308, С. 114612 - 114612

Опубликована: Фев. 8, 2022

The intensive livestock activities that are carried out worldwide to feed the growing human population have led significant environmental problems, such as soil degradation, surface and groundwater pollution. Livestock wastewater (LW) contains high loads of organic matter, nitrogen (N) phosphorus (P). These compounds can promote cultural eutrophication water bodies pose hazards. Therefore, humanity faces an enormous challenge adequately treat LW avoid overexploitation natural resources. This be accomplished through circular bioeconomy approaches, which aim achieve sustainable production using biological resources, LW, feedstock. Circular uses innovative processes produce biomaterials bioenergy, while lowering consumption virgin Microalgae-based treatment (MbWT) has recently received special attention due its low energy demand, robust capacity microalgae grow under different conditions possibility recover transform nutrients into highly valuable bioactive compounds. Some high-value products may obtained MbWT biomass pigments for food animal feed, nutraceuticals, biofuels, polyunsaturated fatty acids, carotenoids, phycobiliproteins fertilizers. article reviews recent advances in (including swine, cattle poultry wastewater). Additionally, most factors affecting nutrient removal productivity addressed, including: (1) microbiological aspects, strain used interactions between microbial populations; (2) physical parameters, temperature, light intensity photoperiods; (3) chemical C/N ratio, pH presence inhibitory Finally, strategies enhance productivity, acclimation, UV mutagenesis multiple culture stages monocultures multicultures) discussed.

Immobilized microalgal system: An achievable idea for upgrading current microalgal wastewater treatment

Environmental Science and Ecotechnology, Год журнала: 2022, Номер 14, С. 100227 - 100227

Опубликована: Ноя. 19, 2022

Efficient wastewater treatment accompanied by sustainable "nutrients/pollutants waste-wastewater-resources/energy nexus" management is acting as a prominent and urgent global issue since severe pollution has occurred increasingly. Diverting wastes from into the value-added microalgal-biomass stream promising goal using biological technologies. This review proposed an idea of upgrading current microalgal immobilized system. Firstly, systematic analysis immobilization technology displayed through in-depth discussion on why microalgae for treatment. Subsequently, main technical approaches employed pollutant removal mechanisms are summarized. Furthermore, high-tech technologies to promote large-scale production application potentials in diverse bioreactors downstream applications lead upgradation closer, feasibility existing systems thoroughly discussed. Eventually, several research directions toward future system upgrading. Together, it appears that further microalgae-based can be recognized achievable alternative make more realistic. The information perspectives provided this also offer feasible reference conventional
