Its anti-virulence properties were evaluated against Escherichia coli O157: H7, Listeria monocytogenes, Pseudomonas aeruginosa, Salmonella enterica sub. enterica serovar Typhimurium and Staphylococcus aureus. The bismuth complex was characterized by NMR, UV-Vis, FTIR, ESI/MS and TG. Furthermore, Bi-edtabz complex at 0.25–1 mM presented better antibiofilm properties against E. coli O157: H7 and S. aureus with values of biomass reduction of 30.1–57.1% and 37.8–55.5%, respectively, compared with the ligand edtabz. While biofilm formation of L. monocytogenes, P. aeruginosa and Salmonella Typhimurium was most impaired by edtabz (biomass reduction of 66.1–100%, 66.4–88.0% and 50.9–67.1%), respectively. Additionally, Bi-edtabz inhibited the swimming motility of E. coli O157: H7 (12.5%) and colony spread of S. aureus (47.2%) at 1 mM and inhibited violacein production, a quorum-sensing related pigment of the biosensor strain Chromobacterium violaceum. Hence, edtabz and the Bi-edtabz complex can be used as novel anti-virulence agents against pathogenic bacteria.","PeriodicalId":103253,"journal":{"name":"PeerJ Inorganic Chemistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130838102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jiang-Gu fractionation gave similar Ca bounded P to that Tiessen-Moir did at low P level but greater contents at high P level. The two methods extracted much comparable total inorganic P. However, Tiessen-Moir method accounted less total organic P than ignition or Jiang-Gu method (the organic P (Po) estimated by subtract the total inorganic P (Pi) in Jiang-Gu fractionation from the total).
