The prevalence of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) is threatening human health, while the emerging contaminant microplastics (MPs) may pose challenges for disinfection to remove ARB and ARGs. This study aims to investigate the effect and possible mechanism of polyethylene microplastics (PE-MPs) on the efficacy of chlorination of ARB and ARGs. The results indicated that PE-MPs hindered the effectiveness of chlorine inactivation of ARB with the reduction of 0.99–1.88 lg for antibiotic resistant Escherichia coli and 0.80–1.69 lg for antibiotic resistant Enterococcus faecalis. With the presence of PE-MPs, disinfected ARB survived more and regrew better when sufficient nutrition was available. The effects of concentration and sizes of PE-MPs, as well as the ambient pH and humic acid, were also studied. The possible mechanism of the negative effect of PE-MPs on ARB inactivation in chlorine disinfection was discussed by studying the attachment of ARB on PE-MPs. It should be the adhesion of ARB on PE-MPs that provided shielding from contact with chlorine. Furthermore, the impact of PE-MPs on degradation of ARGs was also examined. This study highlighted the potential threat of MPs on the control of antibiotic resistance in water. © 2024, The Authors. All rights reserved.

China is vigorously promoting garbage classification, but the treatment of classified waste, especially household food waste (HFW) has yet to be studied. Lactic acid (LA), a high value-added platform molecule has broad market prospects. Although there have been many studies on the production of LA from food waste, open fermentation often produces lots of by-products, while the traditional fermentation under a pure bacteria system often requires the saccharification process, which increases the production cost. We sought to analyze the comprehensive properties of classified HFW in Shanghai, then to produce LA by inoculating lactic acid bacteria (LAB) directly. The effects of strains, temperature, sterilized or not, initial pH, inoculum size, and substrate concentration on LA production were investigated. HFW was rich in nutrients and grow factors which provided the possibility for direct LA production from HFW by inoculating LAB. The results showed that Lactobacillus rhamnosus ATCC 7469, Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus all could be used as the inoculum, however, no significant synergistic effect of the three strains on LA production was found. LA concentration of 30.25 g/L at 37 °C , pH 6.8 could be obtained by inoculating Lactobacillus rhamnosus ATCC 7469 from sterilized HFW. High inoculum size and substrate concentration resulted in high LA concentration, but not high LA yield. The result of ANOVA indicated that there was a significantly positive relationship between substrate concentration and LA concentration (r=0.942, p © 2022, The Authors. All rights reserved.

Biofilm is one of the important factors affecting nitrogen removal in constructed wetlands (CWs). However, the impact of submerged macrophyte on nitrogen transformation of biofilms on leaves of submerged macrophyte and matrix remains poorly understood. In the study, the CWs with Vallisneria natans and with artificial plant were established to investigate the effects of submerged macrophyte on nitrogen transformation and the composition of nitrogen cycling bacteria to probe nitrogen removal functions of biofilms under high ammonium nitrogen (NH4+-N) loading. The average removal rates of total nitrogen and NH4+-N in CW with V. natans reached 71.38% and 82.08%, respectively, showing increases by 24.19% and 28.79% compared with the control with artificial plant. Scanning electron microscope images indicated that high NH4+-N damaged leaf cells, resulting in the release of cellular contents which increased aqueous total organic carbon in CW with V. natans. However, the specific surface area and carrier function of V. natans were unaffected within 25 days. As a kind of natural organic matters, submerged macrophyte provided organic matters for the bacterial growth in biofilms in CW. Bacterial composition analysis revealed that the phylum Proteobacteria was predominant in CW with V. natans. The numbers of nitrifiers and denitrifiers in leaf biofilms reached 1.66 × 105 cells/g and 1.05 × 107 cells/g, as well as 2.79 × 105 cells/g and 7.41 × 107 cells/g in matrix biofilms, respectively. Submerged macrophyte elevated the numbers of nitrogen-converting bacteria and promoted the expression of nitrification (amoA and hao) and denitrification genes (napA, nirS and nosZ) in leaf biofilms and matrix biofilms, which facilitated nitrogen conversion in CW with V. natans. Therefore, this study highlighted the effects of submerged macrophyte on biofilm functions, providing a scientific basis for the nitrogen removal of biofilms in CWs. © 2023, The Authors.

A large amount of household food waste (HFW) is produced yearly, resulting in environmental problems and financial burdens. Bio-production of lactic acid, a high value-added platform molecular, from HFW by anaerobic fermentation is a promising way of resource recovery. However, there is still the problem of low LA production yield. This paper compared several pretreatment methods (hydrothermal pretreatment, chemical pretreatment, and combined hydrothermal and chemical pretreatment) to improve LA production from HFW. The result showed that the combined pretreatment (alkali-thermal pretreatment at pH 10 and 120 °C) significantly increased the LA production than single hydrothermal and chemical pretreatment. The pretreatment process promoted the dissolution of organics, especially the polysaccharides and growth factors (amino acids), and further influenced the LA production by Lactobacillus rhamnosus ATCC 7469. Among the amino acids, Asp, Thr, Glu, Gly, Ala, Cys, Val, Ile, Arg, and Pro significantly correlated with LA concentrations. © 2022, The Authors. All rights reserved.

The aggregation of antiviral drugs (ATVs) in waste activated sludge (WAS) and their migration and transformation during WAS treatment pose considerable environmental exposure, so it is crucial to understand the behavior of these agents during WAS treatment. This study investigated the effects of ritonavir (RIT), an ATV used to treat human immunodeficiency virus infection and coronavirus disease 2019, on anaerobic digestion (AD) of WAS to reveal the mechanisms by which it interferes with anaerobic flora. The dosage influence results showed that methane production in AD of WAS decreased by 46.56% when RIT concentration was increased to 1000 μg/kg total solids (TS). The AD staging test revealed that RIT mainly stimulated microbial synthesis of the extracellular polymeric substance (EPS), limiting organic matter solubilization. At 500 μg/kg TS, RIT decreased CHO and CHON levels in dissolved organic matter by 23.12% and 56.68%, respectively, significantly reducing substrate availability to microorganisms. Metagenomic analysis of microbial functional gene sets revealed that RIT had greater inhibitory effects on protein and amino acid metabolism than on carbohydrate metabolism. Under RIT stress, methanogens switched from hydrogenotrophic and acetotrophic methanogenesis to methylotrophic and acetotrophic methanogenesis. © 2024, The Authors. All rights reserved.

Antibiotics can restrain the microbial communities and functions in aquatic systems. However, the influencing mechanism of ENR on the growth of submerged macrophyte and nitrogen transformation functions of leaf biofilms on submerged macrophyte remain inadequately elucidated. The result revealed that the content of chlorophyll a and Fv/Fm decreased by 37.66% and 61.20% respectively if initial ENR concentration was 10.0 mg/L. High ENR concentrations injured the leaf cells of V. natans, resulting in the cellular content release that increased the total organic carbon (TOC) in water bodies. Denitrifiers in leaf biofilms could utilize organic matters released by V. natans for denitrification, and their tolerance to ENR were enhanced under high organic matters condition. Quantitative analysis of denitrification functional genes indicated that the ratio of initial ENR to TOC (E/T) of 0.44 was an inflection point from decrease to increase denitrification gene expression. Microorganisms up-regulated amino acid, sugar anabolism and energy metabolism to resist high concentrated ENR stress and promote denitrification. This study established a scientific foundation for antibiotic interference with the nitrogen conversion function of leaf biofilms and the growth of submerged macrophyte. © 2024, The Authors.

The recovery of high value-added products, lactic acid (LA), from household food waste (HFW) by anaerobic fermentation in an open system has attracted more and more attention. However, there has been disagreement on the operation conditions, especially the pH and temperature. In this study, the HFW was fermented in nine semi-continuous reactors at different pH (5.0, 7.0, and 9.0) and temperatures (35 °C, 52 °C, and 70 °C). The result showed that the highest LA production occurred at pH7_70 with a concentration of 17.75 ± 1.51 g/L, accounting for 76%. The highest volatile fatty acids concentration occurred at pH 9 under mesophilic conditions with a concentration of 24.37 ± 1.31 g/L, and the acetic acid was the main component of VFAs, accounting for 62%. A significant positive correlation was found between relative activities of lactic dehydrogenase (LDH) and LA concentration, r = 0.928, p © 2022, The Authors. All rights reserved.

The recovery of high value-added products, lactic acid (LA) from household food waste (HFW) by anaerobic fermentation has attracted more and more attention. There are few studies on the production of LA by anaerobic fermentation under hyperthermophilic conditions. In this study, the LA was produced by anaerobic fermentation from HFW under hyperthermophilic conditions (70 ± 1 °C) and different pH values (5.0, 7.0, and 9.0), and compared with the LA production under mesophilic (35 ± 1 °C) and thermophilic (52 ± 1 °C) conditions. The result showed that the highest LA production occurred at pH7_70 with a concentration of 17.75 ± 1.51 g/L. The solubilization of organics, high activities of lactic dehydrogenase (LDH), and low activities of acetate kinase (ACK) resulted in high LA concentration and proportion under hyperthermophilic conditions. The result of microbial community structures showed that LA production at 70 °C was dominated by Lactobacillus and Clostridium. © 2022, The Authors. All rights reserved.
