Mixtures containing hormetic components are likely to induce hormesis. However, due to the presence of stimulatory effects, predicting the toxicity of such mixtures and identifying their key components face challenges. This study investigated the complex relationship between the stimulatory effects of individual components and their mixtures, focusing on predicting mixture toxicity and identifying key components influencing this toxicity. Sixteen chemicals, commonly found in disinfectants and hand sanitizers, were selected to construct a complex mixture system containing hormetic components. Using Vibrio qinghaiensis sp.-Q67 as an indicator organism, the study employed microplate toxicity tests to collect toxicity data for individual chemicals and their mixtures. The independent action (IA) and back-propagation neural network (BPNN) methods were utilized to predict mixture toxicity, while global sensitivity analysis (GSA) identified key components affecting toxicity. Results revealed that six of the sixteen chemicals exhibited time-dependent hormesis. However, when combined into mixtures, the stimulatory effects observed in individual components tended to diminish or disappear, leading to higher overall toxicity, likely due to synergism. Traditional models like the IA significantly underestimated mixture toxicity, whereas the BPNN model demonstrated superior predictive performance. GSA identified five key components, and changes in the levels of some non-toxic components significantly altered the toxicity of the mixtures. Moreover, increasing the levels of certain key components could either increase or decrease the mixture's toxicity, making the strategy of reducing their concentration to control mixture toxicity ineffective. This study revealed the potential of neural networks in predicting the toxicity of mixtures containing hormetic components and the possible characteristics of the effects of key components on mixture toxicity. © 2024 Elsevier B.V.

Reducing the oral bioavailability of metal contaminants including As, Cd, and Pb in foods can protect human health. Studies showed reduced metal bioavailability with elevated Ca and Fe intake;however, the effectiveness of enhancing food Ca and Fe bioavailability remains unknown. Based on a mouse bioassay and using metal accumulation in mouse tissues (kidneys and liver) as the bioavailability endpoint, this study investigated the roles of casein phosphopeptides (CPP, food nutrition fortifier) in lowering the As, Cd, and Pb bioavailability from consuming a metal-contaminated wheat. The CPP amendment at 0.10–0.50% in wheat promoted its Ca bioavailability, causing 33–62% and 59–80% decreases in the gene expression encoding for duodenal Ca and phosphate transporters in mice. This limited transcellular transport of Cd²⁺ and inorganic arsenate via Ca and phosphate transporters respectively, thus leading to 27% and 34% decreases in Cd and As contents in mouse kidneys fed with wheat at 0.50% CPP amendment. In addition, CPP promoted the colonization of Feacalibaculum and Bifidobacterium in mouse gut, likely promoting As excretion in feces by 81–112%. In contrast to As, and Cd, CPP failed to reduce Pb contents in mouse tissue after consuming CPP-amended wheat, probably by elevating wheat-Pb solubility in the intestinal fluid by 48–136%. However, co-amendment of 0.30% CPP and 500 μg g⁻¹ Ca as Ca gluconate lowered the As, Cd, and Pb contents in mouse kidneys by 38–71%. The data indicate that fortifying Ca together with CPP in wheat can reduce human exposure to multi-metals via dietary intake. © 2024 The Author(s)

China is vigorously promoting garbage classification, but the treatment of classified waste, especially household food waste (HFW) remains to be studied. We aimed to analyze the comprehensive properties of classified HFW in Shanghai, then to produce lactic acid (LA), a high value-added platform molecule 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. The results showed that 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. In addition, an average LA concentration of 26.8 g/L, LA yield of 0.20 g COD/g TCOD was obtained by repeated batch fermentation for 32 d. © 2022, The Authors. All rights reserved.

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.

Direct Lactic Acid Production from Household Food Waste by Lactic Acid Bacteria

SSRN

SSRN 2022年

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.

Submerged Macrophyte Promoted Nitrogen Removal Function of Biofilms in Constructed Wetland

SSRN

SSRN 2023年

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.
