These aquatic ecosystems are primarily polluted by potentially toxic elements, polyaromatic hydrocarbons, dyes, plastics, pesticides, organic compounds, and molecules present in fertilizers, household wastes, industrial effluents, and sewage discharge. The enhanced deterioration of water bodies has led to the search for natural solutions for a sustainable ecosystem. The utilization of the natural microbial flora of the aquatic ecosystem for remediation, more popularly known as bioremediation, is of global interest because of its cost-effectiveness and eco-friendly approach. Bioremediation can be broadly categorized into bacterial remediation, mycoremediation, and phytoremediation and is more commonly studied for soil pollution. However, in this review, we discuss bioremediation techniques and mechanisms with respect to water pollution. Aquatic microbes utilize the toxic components present in wastewater as a substrate for their own metabolism by acting as a biologically active methylator or by chemical alteration of the toxicants into less harmful products, thus degrading the toxic environmental pollutants into nontoxic products thereby eliminating their detrimental effects. Microalgae used in phytoremediation also help to elevate the dissolved oxygen level in the aquatic ecosystem thereby reducing the probability of eutrophication.

The anaerobic degradation is a promising technique for the removal of recalcitrant aromatic hydrocarbons from waste stream. In this study, anaerobic degradation of naphthalene (NAP) was investigated by using cow dung-enriched mixed microbial consortia with varying NAP and sulfate concentrations. The maximum removal of NAP (99.8%) and sulfate (68%) was achieved while varying the sulfate concentration from 50 to 500 mg/L in 500 mg/L NAP influent concentration. 41.9 mg/L of sulfate was generated during this study. Similarly, when NAP concentration was varied from 100 to 1000 mg/L, 84% of chemical oxygen demand (COD), 74% of sulfate, and 92% of NAP were observed at constant sulfate concentration of 250 mg/L. This result reveals that sulfate concentration had no significant effect on NAP degradation. NAP mineralization was evidenced by the formation of sulfide and production of metabolites with decreasing NAP concentration. Gas chromatography–mass spectrometry (GC–MS) confirmed the formation of metabolites like naphthol and 1,2-dihydroxynaphthalene due to monooxygenation at C-1 as part of the metabolic pathway. The rate of NAP, COD, and sulfate removal followed the first-order kinetics with high regression coefficients while varying the influent NAP concentrations.</p>\u0000 </div>","PeriodicalId":10306,"journal":{"name":"Clean-soil Air Water","volume":"52 12","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The six prepared bio-adsorbents were tested to verify the adsorption capacity as gross residues, after carbonization, and after alkaline-chemical activation. Bench-scale experiments conducted at different conditions showed that experimental data were better described by the Langmuir isotherm, by the intraparticle diffusion model (with external diffusion being the dominant step), followed by the pseudo-second-order model, indicating the predominance of monolayer chemisorption. In addition, maximum adsorption capacities ranged between 10.55 and 25.51 mg/g, with a higher dye removal rate at alkaline pH. The adsorption of the MB dye onto the six produced bio-adsorbents occurred through both polar and nonpolar interactions.

An increase in nitrogen load results in depletion of dissolved oxygen (DO), eutrophication, ecological stress, and biodiversity loss. Intake of water containing excess nitrate can cause different diseases. Conventional physicochemical nitrogen removal techniques are expensive and also generate secondary pollutants. In contrast, biological methods offer effective and economical outcomes with global acceptance. Biofilm-based techniques have the advantages of low space requirement, resistance toward toxic shocks, and absence of sludge backflow. The carriers used in biofilm reactors allow the growth of heterogeneous microbial consortia, which can simultaneously remove COD, nitrogenous compounds, and phosphates. This review aims to summarize the outcomes of the individual lab-scale research in this area, critically analyze the scientific findings, and understand the research gap. Conventional nitrification–denitrification and anammox have often been replaced by more efficient approaches such as simultaneous nitrification–denitrification, partial nitrification–denitrification, partial nitritation and anammox, and simultaneous partial nitrification, anammox, and denitrification. Multistage moving bed biofilm reactors have been specially designed with step feeding for complete nitrogen removal. Through anammox in a sequencing batch reactor, a high rate of denitrification could be obtained, whereas simultaneous nitrification–denitrification using a membrane bioreactor resulted in almost complete removal of nitrogen.
