A hydroponic experiment was conducted to investigate the growth and nutrient uptake by water hyacinth ( Eichhornia crassipes ) under the combined stress of typical veterinary antibiotic tetracyclines (TCs) with copper (Cu). Although E. crassipes proved relatively high tolerance to the co-contamination of Cu and TCs, the plant growth and nutrient uptake were significantly and interactively influenced by co-contamination between Cu and TCs after 20 days of growth. The inhibitory effects of Cu or TCs were more evident on physiological parameters than morphological parameters. An increase in the concentrations of Cu or TCs in solution was associated with a greater decrease in plant growth and nutrient uptake. The growth of shoots and nitrogen (N) and phosphorus (P) uptake by shoots were less affected by Cu/TCs compared to roots. The inhibitory effect of TCs on plants growth and nutrient uptake was much stronger than that of Cu, but the opposite was true for N and P concentrations in plant tissues. The mixture of TCs with the low-Cu showed a reduction in plant growth and nutrient uptake compared with the sole treatments of TCs; while the inhibition was alleviated with increases of Cu concentrations in solution. Therefore, the interactive effects of TCs and Cu should be taken into consideration to achieve a better knowledge on phytotoxicity and bioavailability of co-contamination between antibiotics and heavy metals to aquatic plants.

The interaction effects of four chlorine-free admixtures such as calcium formate (CF), triethanolamine, (TEA), triisopropanolamine (TIPA), and sodium sulfate (SS) on the compressive strength development of Portland cement mortars were investigated based on the design of experiment (DoE). The results showed that both the addition of CF and SS contributed significantly to the strength of cement mortars at early curing age. However, the interaction of CF and SS could hinder their respective positive effect on the strength of cement at 1 d. At later curing ages, CF was still beneficial in improving the late strength of cement, but SS had a negative effect on the strength of cement at 28 d. A negative effect of TIPA on the strength of cement was found at 3 d. However, the positive interactive effect of TIPA and CF was sufficient to offset the negative effect of TIPA on the strength of mortars at 3 d if the dosage of CF exceeded 2%. In addition, TEA had a positive influence on 7 d strength until a turning point was reached and the optimum dosage of TEA was approximately 0.013%.

Probiotics are live microorganisms offering various health benefits to hosts, but exposure to adverse conditions can compromise their viability during gastrointestinal transit. Probiotics in the biofilm state have been proven as an alternative way to the probiotic survival challenge; however, knowledge of mixed-species biofilms by probiotics is limited. This study aimed to examine the ecological interactions between Lactiplantibacillus plantarum LP-52 and Limosilactobacillus fermentum LF-56 from a phenotypic and metabolomics perspective during their mixed-species biofilm development. In specific, we investigated how their interaction changes bacterial growth, biofilm-forming capacity, biofilm structure, biofilm metabolic activity, EPS production, and biofilm tolerance under gastrointestinal conditions. Moreover, a comprehensive metabolomics analysis was conducted to identify different metabolic profiles and elucidate the underlying mechanisms during the development of mixed-species biofilm. Results showed that their cooperative interaction significantly promoted the planktonic cell growth of L. fermentum LF-56 and L. plantarum LP-52 during their co-cultivation. The synergistic effect also markedly improved the biofilm formation, with increased cell counts in biofilms and higher metabolic activity when compared to each single-species biofilm. Confocal laser scanning microscopy imaging showed denser and more diverse structures of mixed-species biofilm with higher coverage and thickness. In addition, dual-species biofilms were best tolerated under simulated gastric and intestinal conditions. Untargeted metabolomics assay identified 852 differential metabolites, primarily associated with seven pathways: two pathways of nucleotide metabolism (purine metabolism, pyrimidine metabolism), two pathways of carbohydrate metabolism (TCA cycle, glycolysis), alanine, aspartate, and glutamate metabolism, riboflavin metabolism, and ABC transporters, which an enhanced energy metabolism, stress adaptation, and potential biofunctional benefits. With this respect, this investigation underscores the benefits of mixed probiotics biofilms and contributes to further application of probiotics in the food and biotechnology industry.

This study aims to investigate the influence of the interactions between the major aromatic compounds in Baijiu (esters and acids) on the aroma and taste profile of Baijiu. The electronic nose and electronic tongue were used to assess the effects of adding acids on the aroma and taste of Baijiu. Results indicate that the incorporation of acids remarkably alters the olfactory intensity of Baijiu, with minimal impact on its taste, thereby confirming the profound influence of ester–acid interactions on volatile aroma components. Furthermore, the best-estimated threshold method was utilized to determine the aroma thresholds of four key esters and their corresponding acids. Butyric, hexanoic, and lactic acids exhibit synergistic effects by substantially lowering the aroma thresholds of their respective esters. By contrast, acetic acid exerts a masking effect, thereby elevating the aroma threshold of ethyl acetate. Sensory evaluation corroborated the influence of ester–acid interactions on the overall aroma of Baijiu, which is consistent with the aroma threshold findings. Molecular docking methods were applied to decipher the mechanism underlying ester–acid interactions. Hydrogen bonding emerges as a pivotal interaction mode among aromatic compounds, with the binding energy intimately linked to the extent of synergy or masking effects.

A highly eff ;ective phenanthrene (PHE)-degrading co-culture containing Rhodococcus sp. WB9 and Mycobacterium sp. WY10 was constructed and completely degraded 100 mg L −1 PHE within 36 h, showing improved degradation rate compared to their monocultures. In the co-culture, strain WY10 played a predominant role in PHE degradation. 1-hydroxy-2-naphthoic acid was an end-product of PHE degradation by strain WB9 and accumulated in the culture medium to serve as a substrate for strain WY10 growth, thereby accelerating PHE degradation. In turn, strain WY10 degraded PHE and 1-hydroxy-2-naphthoic acid intracellularly to form phthalate and protocatechuate that were exported to the culture medium through efflux transporters. However, strain WY10 cannot take up extracellular phthalate due to the absence of phthalate transporters, restricting phthalate degradation and PHE mineralization. In the co-culture, phthalate and protocatechuate accumulated in the culture medium were taken up and degraded towards TCA cycle by strain WB9. Therefore, the metabolic cross-feeding of strains WB9 and WY10 accelerated PHE degradation and mineralization. These findings exhibiting the synergistic degradation of PHE in the bacterial co-culture will facilitate its bioremediation application.

Biomass and pig manure have distinct compositions and the co-pyrolysis of them has gained much attention. However, the influence of volatiles interaction on the properties of the char was still unclear. In this study, lignin was selected as the model component of biomass with pig manure for co-pyrolysis at 600 °C. The results indicate that volatiles from co-pyrolysis promoted re-condensation reaction, resulting in the higher char yield (48.0% in co-pyrolysis versus 31.0% in pyrolysis of single manure) and the formation of more aromatics in bio-oil. The co-pyrolysis also facilitated the dehydrogenation and dehydration reactions, which accounted for the elimination of oxygen and nitrogen contents and thus a higher carbon content (64.7% in the co-pyrolysis versus the averaged value of 46.4% from the pyrolysis of single feedstock), higher crystallinity and thermal stability of the char. The in-situ diffuse reflection infrared Fourier transform spectroscopy (DRIFTS) characterization results demonstrated that the functionalities abundances of char with temperature was influenced by volatiles interaction via accelerating the carbonization reaction. In addition, the high heating value (HHV) of char was obviously improved by cross-interaction of volatiles during co-pyrolysis (24.4 MJ/Kg in co-pyrolysis versus averaged value of 15.1 MJ/Kg from single pyrolysis), implying that the co-pyrolysis enhanced the energy density of the resulting char.

Si 3 N 4 is a candidate crucible material for Si–B alloys in high temperature thermal energy storage system. In this regard, the phase formation in the Si–B alloys and the interaction between the alloys and Si 3 N 4 were investigated in an induction furnace at 1750 °C with the B addition of 2, 5, 8, and 11 mass %, respectively. Moreover, the wettability property of the Si-3.25B alloy (mass %) on Si 3 N 4 substrate was examined at temperatures up to 1400 °C. The cross-sectional images and micro-analyses showed that BN precipitates were produced in the Si–B alloys and a BN layer was formed at the interface between the Si–B alloys and Si 3 N 4 . However, the amount of BN precipitates was negligible. Next, the equilibrium contact angle of liquid Si-3.25B alloy on Si 3 N 4 substrate was determined to be 134 ± 1°, which indicates non-wetting behavior. The above results support that Si 3 N 4 is a desirable refractory material for the high temperature thermal energy storage system.

Iron reduction impacts the mobilization and thionation of diphenylarsinic acid (DPAA) in soil, but the contribution of crystalline and non-crystalline iron remains unknown. A paddy soil deficient in non-crystalline iron (P-Fe o ), crystalline and non-crystalline iron (P-Fe d ) were incubated with sulfate-plus-lactate, and the results were compared with paddy soil (P) in our previous study. For treatments without ferrous sulfide (FeS) precipitation, the solution-to-solid ratio ( R L/S ) of DPAA increased slightly and dramatically with iron reduction, respectively, for P-Fe o and P, suggesting that the reduction of non-crystalline iron contributes more to DPAA mobilization than crystalline iron. The R L/S was > 0.667 and ≤ 0.667 for treatments without and with FeS, respectively, in P and P-Fe o but not P-Fe d , indicating that crystalline, rather than non-crystalline iron contributes more to DPAA sequestration through reduction and the subsequent FeS precipitation. The degree to which iron reduction facilitates DPAA mobilization or sequestration is likely determined by the composition and amount of iron in paddy soil, respectively. For treatments with FeS, the DPAA transformation rate was < 44 % and 74–86 %, respectively, in P-Fe o and P-Fe d after 90 days, with the maximum value comparable to those without FeS in P after 30 days. This suggests that the crystalline iron in P-Fe o and the residual, small amount of non-crystalline iron in P-Fe d could reduce DPAA thionation by forming FeS, and such effect seems to depend on both the composition and the amount of iron in paddy soil. The results would deepen our understanding of the “As-Fe-S” interactions in soil.

The mathematical model of lithium iron phosphate prepared by hydrothermal method was established by factor experimental design. The effect of individual variables and their interactions were studied by the main effects plot and Interaction plot. The influence of ascorbic acid dosage on the discharge specific capacity was greater than the hydrothermal time and the hydrothermal temperature, and the influence degree of the latter two was equivalent and the interaction effect of hydrothermal time and ascorbic acid dosage has the greatest influence on the discharge specific capacity in three interaction effects. The optimized hydrothermal condition was hydrothermal time of 9 hours, hydrothermal temperature of 210°C and ascorbic acid dosage of 1.5 mmol in the experimental design range, with the initial discharge specific capacity of 0.1 C as 152.5 mAh g −1 . The corresponding characterization was performed using electrochemical methods, XRD, SEM, and TEM. This study provided a protocol to factorially design better experiments to achieve excellent battery criterion in the context of lithium iron phosphate preparation.

To reduce the pollution during the pyrolysis recovery of chlorine-containing plastic waste from different sources, effects of the interaction between different plastics and polyvinyl chloride (PVC) on the transformation of chlorine at low temperature were investigated by thermogravimetry-Fourier transform infrared (TG-FTIR) and fixed-bed pyrolysis experiments. Results showed that the proportions of chlorine in chars were all <0.04 %, indicating that almost all chlorine was released after pyrolysis. However, the chlorine forms in volatiles were significantly changed with mixing different plastics. HCl production was significantly inhibited due to the addition of other plastics, while the organic chlorinated compounds (OCCs) formation was promoted, which increased the distribution of chlorine in liquid products. During PVC pyrolysis, chlorine was mainly distributed in gas (93.09 %) in the form of HCl, only a small amount of aliphatic chlorides were generated and distributed in liquid (6.89 %). After the addition of polystyrene (PS), polyethylene (PE) and polyethylene terephthalate (PET), the chlorine distribution in liquid increased to 8.86 %, 11.98 % and 25.99 %, respectively. The formation of OCCs was significantly affected by the difference in thermochemical reaction characteristics of plastics. Specifically, the production of aromatic chlorides was promoted by PS, while the generation of aliphatic chlorides and aromatic chloroesters was significantly promoted by PE and PET, respectively. Therefore, the release form of chlorine could be significantly altered by the interaction between PVC and other waste plastics, which provides a reference for the regulation of chlorine-containing pollutants in the recovery and utilization of plastic waste.

Acrylamide (AA) and ochratoxin A (OTA) are contaminants that co-exist in the same foods, and may create a serious threat to human health. However, the combined effects of AA and OTA on intestinal epithelial cells remain unclear. The purpose of this research was to investigate the effects of AA and OTA individually and collectively on Caco-2 cells. The results showed that AA and OTA significantly inhibited Caco-2 cell viability in a concentration- and time-dependent manner, decreased transepithelial electrical resistance (TEER) values, and increased the lucifer yellow (LY) permeabilization, lactate dehydrogenase (LDH) release and reactive oxygen species (ROS) levels. In addition, the levels of IL-1β, IL-6, and TNF-α increased, while the levels of IL-10 decreased after AA and OTA treatment. Western blot analysis revealed that AA and OTA damaged the intestinal barrier by reducing the expression of the tight junction (TJ) protein. The collective effects of AA and OTA exhibited enhanced toxicity compared to either single compound and, for most of the intestinal barrier function indicators, AA and OTA combined exposure tended to produce synergistic toxicity to Caco-2 cells. Overall, this research suggests the possibility of toxic reactions arising from the interaction of toxic substances present in foodstuffs with those produced during processing.Keywords:acrylamide;ochratoxin A;Caco-2 cells;tight junction;interactive effects

In this study, the co-pyrolysis of pig manure with cellulose and glucose were investigated at various heating rates. The results demonstrated that potential cross-interaction of the volatiles from the co-pyrolysis facilitated the cracking reaction, resulted in the formation of less charry products and less tarry compounds in the co-pyrolysis. The volatiles interaction also enhanced the evolution of the organics with the π-conjugated ring structures in the bio-oil and remarkably affect the char properties. The dehydration and condensation reactions were promoted during the fast co-pyrolysis of manure with cellulose and glucose, leading to the increased carbon content (from 20.0%–46.5 and 43.0 %), the higher thermal stability, and the enhanced crystallinity of carbon structure in the char formed. In addition, the in-situ Diffuse Reflection Infrared Fourier Transform Spectroscopy (DRIFTS) characterization indicates that the interaction of volatiles in the co-pyrolysis obviously affected the evolution of the functionalities of the char and the reaction network. Additionally, the HHV (37.2 and 37.9 vs 28.0 MJ/Kg) and the energy yield (66.3 and 68.2 vs 66.2 %) of the char from the co-pyrolysis was higher than that of the manure, which was beneficial for the utilize of the char as solid fuel.
