The nutrient-deficient conditions coupled with the presence of nitrate-reducing bacteria (NRB) within these pipelines facilitate microbiologically influenced corrosion, wherein bacteria directly interact with the metal to harvest electrons for metabolic processes. Our findings indicate that GE inhibits microbial corrosion through dual mechanisms: significantly reducing biofilm formation and adsorbing onto the metal surface. Biofilm inhibition was assessed through both qualitative and quantitative assessments, employing light microscopy and confocal laser scanning microscopy (CLSM) to visualize and confirm the suppression of biofilm development by NRB in the presence of GE. Electrochemical techniques, including electrochemical impedance spectroscopy (EIS) and polarization measurements, demonstrated that GE achieved an inhibition efficiency nearing 95%. Further analysis via scanning electron microscopy (SEM) and adsorption studies corroborated the effective adsorption of GE on carbon steel, highlighting the importance of concentration and immersion time in performance outcomes. Notably, elevated concentrations of GE were found to enhance inhibitory effects, with a 7-day exposure period yielding optimal surface coverage. These results establish GE as a promising and environmentally friendly alternative for mitigating microbial corrosion in industrial applications. PRACTITIONER POINTS: The presence of nitrate-reducing bacteria (NRB) and a nutrient-starved environment are commonplace in the coolant pipes carrying water and can cause severe damage to carbon steel pipes. Ginger extract (GE), an inexpensive green corrosion inhibitor, can be a potent microbial corrosion inhibitor in petrochemical industries. The high efficiency (95%), achieved with ginger extract (GE), is due to its dual-acting mechanism: It inhibits the formation of bacterial biofilm on the surface of carbon steel by providing a non-conducive environment for bacterial growth. The components of GE get adsorbed over the surface of carbon steel and hence prevent bacterial attachment. An optimal concentration of 0.5 g/L GE was required to exhibit high efficiency (95%), which can be achieved on 7 days of exposure of carbon steel to GE, in the presence of NRB in a nutrient-starved environment.</p>","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 2","pages":"e70015"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081283","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}

In order to treat dairy and municipal wastewater, this study assesses the efficacy of a two-stage hybrid constructed wetland (CW) system. The WWQI is the primary focus of this evaluation over a range of mixing ratios. Before and after treatment, many physicochemical parameters were examined, including pH, total suspended solids (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total phosphorus (TP), ammonia nitrogen ( <math> <semantics> <mrow><msub><mi>NH</mi> <mn>3</mn></msub> <mo>-</mo> <mi>N</mi></mrow> <annotation>$$ {NH}_3-N $$</annotation></semantics> </math> ), and nitrate nitrogen ( <math> <semantics> <mrow><msub><mi>NO</mi> <mn>3</mn></msub> <mo>-</mo> <mi>N</mi></mrow> <annotation>$$ {NO}_3-N $$</annotation></semantics> </math> ). The hybrid CWs system dramatically lowers pollutant concentrations, according to the results, with combinations containing higher amounts of MWW showing the best results. The WWQI values, which change from \"unfit for any uses\" in untreated DWW to \"excellent\" quality in treated MWW, show these advancements. The results highlight the potential of hybrid CWs as an effective and sustainable wastewater treatment method, especially when it comes to maximizing the proportion of dairy to municipal wastewater. This study adds to our knowledge of efficient wastewater treatment techniques and highlights the significance of incorporating eco-friendly technologies to tackle water scarcity issues. PRACTITIONER POINTS: Hybrid Constructed Wetlands (HCWs) are effective in removing TSS, BOD, COD, TP, ammonia nitrogen, and nitrate nitrogen from dairy and municipal wastewater. On the basis of HCWs performance determine the Wastewater Quality Index (WWQI) for four different ratio proportions of dairy and municipal wastewater. This index is more useful for water quality status determination and treated water reuse for various purposes. This also benefits sustainable treatment technology and contributes to achieving SDGs.</p>","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 2","pages":"e70024"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081289","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}

Microbial remediation is an effective method for removing thin oil slick contamination. In this study, the adsorption and degradation of low-concentration oil spills by Chlorella vulgaris LH-1 immobilized in konjac glucomannan (KGM) aerogel were investigated. The effect of the KGM aerogel-immobilized C. vulgaris on the bacterial community structure in seawater environments was analyzed through bacterial diversity sequencing. In seawater containing 0.01 and 1.00 g/L of crude oil, after 14 days of remediation with the KGM aerogel-immobilized C. vulgaris, crude oil removal rates of 98.73% and 95.13% were achieved, respectively. The FDA hydrolytic enzyme activity curve indicated that the microbial growth activity in the immobilized C. vulgaris group was significantly higher than that in other groups. After remediation, the top three dominant bacterial genera in the seawater were found to be Vitellibacter, Roseitalea, and Methylophaga. Vitellibacter, a genus known for its ability to degrade polycyclic aromatic hydrocarbons (PAHs) in marine environments, showed increased abundance in seawater treated with the KGM aerogel-immobilized C. vulgaris, suggesting enhanced PAH degradation capability in the presence of the immobilized C. vulgaris. Functional prediction using PICRUSt indicated that the oil metabolism capability of bacteria was promoted by the KGM aerogel-immobilized C. vulgaris. PRACTITIONER POINTS: High degradation efficiency across various oil concentrations is exhibited by KGM-immobilized microalgae. KGM aerogels effectively confine C.vulgaris, reducing loss in marine systems. The impact of KGM aerogel-immobilized C. vulgaris on bacterial community structure in marine environments was analyzed.

The treatments included irrigation with uncontaminated wastewater (WW) as control, Cu-contaminated WW (CuWW), Zn-contaminated WW (ZnWW), and Cu + Zn contaminated WW (CuZnWW) in a completely randomized design. Compared to ZnWW, irrigation with CuWW or CuZnWW had severe effects on growth, physiology, and mineral absorption by wheat. Irrigation with CuWW or CuZnWW reduced shoot length, root length, root and shoot dry weights by 44-45%, 54-56%, 5-6%, and 33-34%, respectively, against WW control. Similarly, these treatments diminished chlorophyll a, b, carotenoids, and SPAD by 33-34%, 59-60%, 49-51%, and 26-27%, respectively. Conversely, contaminated irrigation improved the total polyphenols, polyphenolic acids, total flavonoids, and antiradical activity, however, a maximum increase in these parameters up to 65% was observed when irrigated with ZnWW. Pearson correlation showed that the decline in growth and physiology of wheat was negatively correlated with shoot metal concentration and uptake. Dehydrogenase activity is severely hampered by CuWW or CuZnWW and to a lesser extent by ZnWW as well. These results suggest that irrigation with contaminated WW adversely affects wheat growth and physiology, however, ZnWW is found to be less toxic to wheat crops than Cu. Thereby, this data highlights the need for a tailored approach to prioritize the metal (Zn) with lower toxicity during the use of WW in irrigation practice. PRACTITIONER POINTS: Cu-contaminated wastewater (20 ppm Cu) substantially reduced the growth and physiology of wheat. Zn (80 ppm) contaminated wastewater was found lesser toxic compared to Cu. Wheat irrigation with contaminated wastewater increased biologically active compounds in wheat shoot. Contaminated wastewater affected minerals concentration in the root and shoot part of wheat. Dehydrogenase activity in soil is less affected by Zn-contaminated wastewater.

Y9 were investigated in the presence of diesel oil and simulated radioactive nuclides (Mn²⁺, Co²⁺, Ni²⁺, Sr²⁺, Cs⁺) at varying concentrations, as well as exposure to γ-ray radiation (Co-60). The maximum tolerable concentrations for Co²⁺and Ni²⁺ were found to be 5 mg/l and 25 mg/l, respectively, while the tolerable concentrations for Mn²⁺, Sr²⁺, and Cs⁺ exceeded 400 mg/l, 1000 mg/l, and 1000 mg/l, respectively. A total of 0.4 Gy/h of γ-ray radiation (Co-60) did not significantly affect the growth of strain Y9. The presence of metal nuclides and γ-ray radiation primarily inhibited the production of outer membrane proteins while promoting the secretion of polysaccharides in strain Y9. Strain Y9 exhibited a notable capacity to degrade diesel oil under radiative conditions when exposed to the five individual radionuclides used in this study. Furthermore, the introduction of the radiation-resistant strain R1 significantly enhanced the diesel oil degradation efficiency of strain Y9 in the presence of a mixture of five nuclides, with the degradation efficiency increasing from 26.7% to 46.75%. Strain R1 demonstrated the ability to absorb a substantial amount of free nuclides, thereby creating favorable environmental conditions for the growth and degradation activity of strain Y9.

Membrane materials with special wettability have garnered attention for their ability to achieve efficient oil-water separation by leveraging the differences in wettability at the oil-water interface. These materials are characterized by their simplicity, energy efficiency, environmental friendliness, and reusability. Among them, superhydrophilic-underwater superoleophobic membranes inspired by biomimetic fish scale structures have become a focal point of oil-water separation research due to their ability to repel oil contaminants effectively and maintain self-cleaning properties during the separation process. In this study, a stainless steel microporous two-dimensional metal mesh was employed as the substrate, coated with a carrageenan solution, and gelled in situ using sodium periodate as a crosslinking agent to fabricate a membrane with oil-water separation capabilities. The robust hydrophilicity of the carrageenan hydrogel imparts the coated stainless steel mesh with superhydrophilicity and underwater superoleophobicity (underwater oil contact angle ≥ 158°), along with excellent antifouling properties and recyclability. Experimental results demonstrate that the membrane achieved separation efficiencies of 98.87%, 98.08%, 98.14%, and 97.98% for silicone oil, canola oil, cyclohexane, and liquid paraffin, respectively, with a water flux of 1380.75 L/m²·h. Remarkably, the membrane retained its initial separation efficiency even after 20 cycles. Additionally, the hydrogel exhibited exceptional stability under highly alkaline conditions, making it suitable for the treatment of complex oil-contaminated wastewater.
