This study assessed QS in 22 biofilm samples from full-scale wastewater treatment plants in China. Results showed that the concentration of acyl-homoserine lactones (AHLs) in various biofilm bound forms, ranged from 15.63 to 609.76 ng/g. The highest concentration of AHLs was found in the tightly bound biofilm fraction, while the lowest concentrations were observed in the surface biofilm fraction. Environmental variables, C/N ratio and temperature, were found to be significant factors influencing biofilm AHL distribution (p < 0.01). Higher C/N ratios (ranging from 3 to 12) and low temperatures contributed to the higher concentration of AHLs in biofilms. Dominant AHLs (C10-HSL and C12-HSL) were significantly associated with biofilm activity (R<sup>2</sup> = 0.98/0.97, p < 0.05), with the tightly bound biofilm fraction (TB-biofilm) presenting the highest activity (ATP concentration). Biofilm aging and re-formation processes were more active in the surface biofilm layer (S-biofilm), while the stable structure of the TB-biofilm layer which is attached to the surface of bio-carriers ensures high biofilm activity. This study furthers our understanding of the roles of AHLs in the regulation of mature biofilm activities.","is_dataset_classified":null,"base_score":3.4011973816621555,"endowment":3.4011973816621555,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"31228833","pmcid":null,"openalex_id":"https://openalex.org/W2948279684","authors":[],"funders":[{"funder_name":"Science and Technology Major Project of Guangxi","grant_id":"2017ZX07202003","title":null}],"total_grants":1,"fwci":1.5169,"citation_percentile":0.82763857,"influential_citations":0,"citation_trend":[{"year":2019,"count":1},{"year":2020,"count":6},{"year":2021,"count":4},{"year":2022,"count":9},{"year":2023,"count":1},{"year":2024,"count":3},{"year":2025,"count":2},{"year":2026,"count":3}],"oa_status":"closed","license":"https://www.elsevier.com/legal/tdmrep-license","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0045653519312275?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0045653519312275?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.chemosphere.2019.06.007","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/31228833","host_type":"repository"}],"fields_of_study":["Bacterial biofilms and quorum sensing","Water Treatment and Disinfection","Legionella and Acanthamoeba research","Acyl-Butyrolactones","Biofilms","Carbon","China","Nitrogen","Quorum Sensing","Temperature","Wastewater","Water Purification"],"mesh_terms":["Carbon","China","Nitrogen","Temperature","Biofilms","Water Purification","Quorum Sensing","Acyl-Butyrolactones","Wastewater"],"keywords":["Biofilm","Quorum sensing","Chemistry","Microbiology","Homoserine","Bacteria","Wastewater","Extracellular polymeric substance","Environmental chemistry","Food science","Biology","Environmental engineering","Environmental science","Activity","Quorum Sensing (Qs)","Mature Biofilm","Acyl-homoserine Lactones (Ahls)","Full-scale Wastewater Treatment Plants"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-26T12:50:06.065840Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
