[PMID: 38901697 DOI: 10.1016/j.chemosphere.2024.142640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/20/2024] [Accepted: 06/16/2024] [Indexed: 06/22/2024]
Abstract
Exogenous quorum sensing (QS) molecular can regulate the activity and granulation process of anaerobic sludge in anaerobic digestion process, but would be impractical as a standalone operation. Here we demonstrated that application of 1 mg L-1 boric acid assisted in an upflow anaerobic sludge blanket (UASB) reactor recovery from volatile fatty acids (VFAs) accumulation. After VFAs accumulation, the chemical oxygen demand (COD) removal suddenly reduced from 78.98% to 55.86%. The relative abundance of acetoclastic methanogens decreased from 55.79% to 68.28%-23.14%∼25.41%, and lead to the acetate accumulate as high as 1317.03 mg L-1. Granular sludge disintegrated and the average size of sludge decreased to 586.38 ± 42.45 μm. Application of 1 mg L-1 boric acid activated the interspecies QS signal (AI-2) and then induced the secretion of intraspecies QS signal (N-acyl-homoserine lactones, AHLs). AHLs were then stimulated the growth of syntrophic acetate oxidizing bacteria and hydrogenotrophic methanogen. Moreover, the concentration of acetate decreased to 224.50 mg‧L-1, and the COD removal increased to 75.10% after application of 1 mg L-1 boric acid. The activated AI-2 may induce multiple quorum-sensing circuits enhance the level of AI-2 and AHLs in parallel, and in turn assisted in anaerobic digestion recovery from VFAs accumulation.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 905:167031.

Abstract
Antibiotic resistance residual in piggery wastewater poses serious threat to environment and human health. Biological treatment process is commonly installed to remove nutrient from piggery wastewater and also effective in removing antibiotics to varying degrees. But the specific pathways and mechanisms involved in the removal of antibiotic resistance are not yet well-understood. An integrated anaerobic-aerobic biofilm reactor (IAOBR) has been demonstrated efficient in removing conventional nutrients. It is here shown that the IAOBR effectively removed 79.0% of Sulfonamides, 55.7% of Tetracyclines and 53.6% of Quinones. Antibiotic resistance bacteria (ARB) were simultaneously inactivated by ~0.5 logs. Antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) were decreased by 0.51 logs and 0.42 logs, respectively. The antibiotics were mainly removed through aerobic compartments of the IAOBR. The mass loss of antibiotics in the reactor was achieved by biodegradation and adsorption, accounting for 52.1% and 47.9%, respectively. An obvious accumulation of ARGs was observed in the activated sludge. The potential host of ARGs was analyzed via microbial community and network. Partial least squares-structural equation model and correlation analysis revealed that the enrichment of ARGs was positively affected by MGEs, followed by bacterial community and ARBs, but the effect of antibiotics on ARGs was negative. Outcomes of this study provide valuable insights into the mechanisms of antibiotic resistance removal in biological treatment processes.

Abstract
An analytical method for the simultaneous extraction and determination of eight veterinary antibiotics in swine wastewater and activated sludge was developed and validated based on the instrumental determination by liquid chromatography tandem quadrupole mass spectrometry. Ultrasound-assisted extraction and solid-phase extraction were introduced into the pretreatment procedure of the two complex environmental matrices. The critical steps involved in the sample pretreatment procedure and the instrumental analysis conditions were optimized progressively. Recoveries of the optimized method were good with 75.3-118.2% in wastewater and 82.8-130.1% in sludge. The absolute deviations of methods were lower than 11.7%, presenting a high reproducibility and precision. The limits of quantification for the eight pharmaceuticals in wastewater and sludge were 5-15 ng·L-1 and 2-6 ng·g-1, showing high sensitivity of the methods. The developed method has been successfully applied to evaluate the actual concentration levels of tetracyclines, quinolones, and sulfonamides in actual swine wastewater (maximum detected concentration of 87.377 μg·L-1) and activated sludge (maximum detected concentration of 51242.3 ng·g-1).

Insight into the effect of N-acyl-homoserine lactones-mediated quorum sensing on the microbial social behaviors in a UASB with the regulation of alkalinity. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 800:149413.

Abstract
N-acyl-homoserine lactones (AHLs)-mediated quorum sensing (QS) has been reported as the inducers of microbial social behaviors in anaerobic digestion (AD) processes. However, it is not well understood that how to intentionally change the secretion of AHLs by conventional engineering control such as the regulation of alkalinity. The present research investigated the effect of endogenous AHLs-mediated QS on the microbial social behaviors in an upflow anaerobic sludge bed (UASB) reactor with the influent alkalinity decreased from 2800 mg/L to 700 mg/L by stages. The results showed that the alkalinity of 1800-2200 mg/L was more favorable for the AD in the UASB, with an excellent specific methanogenic activity (SMA) and better microbial aggregation statuses. The alkalinity out of the favorable alkalinity range would decrease the SMA with the accumulation of VFAs in the reactor. It was found that signal molecule C4-HSL was always the dominant AHL in the UASB along with the decrease of influent alkalinity, while 3-oxo-C6-HSL, 3-oxo-C12-HSL and C14-HSL were remarkably improved only within the favorable range of alkalinity. Pearson correlation concluded that the dominant signal molecule C4-HSL was the specific AHL in enhancing the synthesis of extracellular polysaccharide and the metabolism of acidogens. The co-occurrence network revealed that Mesotoga, Sulfurospirillum and Methanoregula were the key hubs in the microbial interaction network, and the AHLs-mediated QS indirectly facilitated the methanogenic metabolism. The present work provided a revealing insight into the effect of AHLs-mediated QS on the microbial social behaviors in AD process with the regulation of alkalinity.

Abstract
In this study, porous spherical carriers were fixed around the hollow fiber membrane module to mitigate membrane biofouling. Two MBRs (R1 without carriers, R2 with carriers) were operated for 31 days under identical operating conditions to investigate the effects of the carriers on the reactor performances, the production of extracellular polymeric substances (EPS), the level of N-acyl-homoserine lactones (AHLs), and the microbial communities. The results showed that the presence of carriers in MBR was conducive to nitrogen removal and decreased the total membrane filtration resistance by about 1.7 times. Slower transmembrane pressure (TMP) rise-up, thinner bio-cakes, lower EPS production, and fewer tryptophan and aromatic proteins substances on the membrane surface were observed in R2. The polysaccharides secretion of EPS in bio-cakes was mainly regulated by C4-HSL and 3OC6-HSL in the presence of carriers. The microbial community analysis revealed that carriers addition reduced the relative abundance of EPS and AHL producing bacteria in the membrane bio-cakes and enriched the accumulation of functional bacteria conducive to nutrient removal in the mixed liquor. This study provided an in-depth understanding for the application of porous spherical carriers to alleviate membrane biofouling.

Abstract
To understand the microbial social behaviors regulated by acyl-homoserine lactones (AHLs) in the upflow anaerobic sludge blanket (UASB) during the restored process after a shock loading, the correlation analyses of AHLs and components of extracellular polymeric substances (EPS), AHLs genes and microbes, and AHLs and microbes were investigated. The results showed that the performance could be restored by regulating influent organic loading rate stage-by-stage. A variation in microbial community and endogenous AHLs was also found during the restoration process. It was found that C14-HSL had improved the synthesis of protein in EPS and resulted in better aggregation of microbes. C4-HSL, as well as C8-HSL and 3-oxoC14-HSL, could prompt the metabolism of acidogenic fermentation bacteria. While 3-oxoC6-HSL was identified as the key signal molecule in enhancing methanogenesis. The present work advanced the understanding of microbial social behaviors and provided an attractive strategy for the restoration of anaerobic digestion after shock loadings.

Abstract
Anammox as a novel biological process in natural nitrogen cycle has been introduced into wastewater treatment process. However, the regulation mechanism of anammox metabolism remained to be investigated. In this study, the specific quorum sensing (QS) signaling molecules for mediating anammox were identified in anammox activity tests. Anammox was valve-regulated by the collaboration of QS signaling molecules N-butyryl-homoserine lactone (C14-HSL) and N-(3-oxotetradecanoyl)-homoserine lactone (3-oxo-C14-HSL), and prompted with the C14-HSL/3-oxo-C14-HSL mole ratio above 1.0. Moreover, the ratio of chemical oxygen demand to total nitrogen (C/N) was identified as an effective regulator for the distribution of C14-HSL and 3-oxo-C14-HSL. An engineering method for control anammox through regulating C/N ratio was proposed and demonstrated based on the performance of two microaerobic reactors treating piggery wastewater and anammox activity tests. The discovery should be of great significance to understanding the social behaviors of anammox bacteria in organic wastewater treatment processes.

Abstract
The primary challenge of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) surviving in wetlands are the rapid and unpredictable environmental changes. To adapt to a fluctuant environment, ammonia oxidizers have to communicate with each other via acyl-homoserine lactones (AHLs). In this study, AOA and AOB in the soil samples taken from Zhalong wetland were incubated. Dynamics of AHLs during the incubation of ammonia oxidizers were measured. Then, the specific AHLs of AOA and AOB were identified, respectively. The results showed that AOA secreted N-butyryl-dl-homoserine lactone (C4-HSL) and N-octanoyl-l-homoserine lactone (C8-HSL) to cope with nitrite accumulation, while they secreted N-(3-oxododecanoyl)-dl-homoserine lactone (OXOC12-HSL) to regulate their ammonium metabolism activity. AOB secreted N-hexanoyl-dl-homoserine lactone (C6-HSL), N-dodecanoyl-l-homoserine lactone (C12-HSL), N-tetradecanoyl-dl-homoserine lactone (C14-HSL) and N-(3-oxododecanoyl)-tetradecanoyl-dl-homoserine lactone (OXOC14-HSL) only to enhance the metabolism activity. The dominant AOA belonged to the Nitrososphaera lineage, while the dominant AOB grouped into the Nitrosomonas lineage. The AHLs receptor homologs were identified in both AOA and AOB, which confirmed that AOA and AOB had the QS system. The present work was the first study that elucidated the QS system of AOA and AOB in multidimensional, and confirmed the role of QS system in ammonia oxidizers' metabolism.

Abstract
A series of dominant functional floras involved in anaerobic digestion was obtained by subculturing anaerobic sludge with specific substrates, respectively, and their specific quorum sensing signals (AHLs) were identified. It was found that most of the AHLs were secreted in starvation of the functional floras. One or two AHLs were found to have a significant positive correlation with the behavior of hydrolytic-fermentative bacteria, homoacetogens, syntrophic propionate-oxidizing bacteria, syntrophic butyrate-oxidizing bacteria and aceticlastic methanogens, respectively. Hydrogenotrophic methanogens had a various self-organization means and broader relations with the other populations, which was induced by six AHLs at least. Performance of an upflow anaerobic sludge blanket in the startup process revealed that the dominant populations involved in anaerobic digestion would secret specific AHLs to induce K-strategy in resource-limited situation for reproduction and regulating their cooperation. This work presents a novel perspective on the social behaviors of microbial populations in anaerobic digestion.

Abstract
Bacteria communicate with one another using chemical signal molecules called autoinducers, and the most prevalent autoinducers used by Gram-negative bacteria are N-acylated homoserine lactones (AHLs). However, AHLs are hardly detected in Shewanella baltica, the specific spoilage organism of Pseudosciaena crocea. In this study, we applied ultrahigh-performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry to determine AHLs. This method enabled the quantification of up to 11 AHLs within 5.6 min with excellent sensitivity (ng/mL level) and linearity (r2 > 0.99), which further detected 9 AHLs produced by S. baltica. Furthermore, by using a biofilm formation assay and statistical analysis, the biofilm-inducing activity of AHL in S. baltica was first revealed. Our results elucidated the physiological role of AHL in S. baltica and provided a satisfactory method to detect AHLs and a statistical model to predict food spoilage properties.
