Its oxidation generates electrons to obtain energy and carbon that is obtained by fixing CO2 from the air. During this aerobic mineral oxidation, metals are solubilized or biodegraded. Metal bioleaching usually is used in biomining and urban biomining approaches to recovery metals such as copper, gold and zinc. Several species of bacterial genus Acidithiobacillus display a great bioleaching activity. Bacterial attachment and biofilm formation are the initial requirements to begin a successful bioleaching process. Biofilm formation in Acidithiobacillus bacteria is strongly regulated by cell to cell communication system called Quorum Sensing. The goal of this chapter is to review the Quorum Sensing system mediated by the autoinducer N-acyl- homoserine-lactones in the Bacterium Acidiothiobacillus ferroxidans, in order to enhance and to boost the bioleaching technologies based in the use of this bacterium. The main applications of the cell-to-cell communication system concepts in A. ferrooxidans are reviewed in this chapter. It is that the addition of synthetic autoinducers molecules, which act as agonist of quorum sensing system, especially those with long acyl chains, both as single molecules (C12-AHL, 3-hydroxy-C12-AHL, C14-AHL, and 3-hydroxy-C14-AHL) or as a mixture (C14-AHL/3- hydroxy-C14-AHL/3-oxo-C14-AHL) increased the adhesion to sulfur and pyrite and enhance the metal bioleaching in urban biomining approaches.","PeriodicalId":121856,"journal":{"name":"Acidophiles - Fundamentals and Applications [Working Title]","volume":"203 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116180362","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}

L. acidophilous is one of the most common probiotics and is used for the treatment of various gastrointestinal, metabolic and inflammatory disorders. L. acidophilous produces antimicrobial compounds, maintains gut permeability and prevents dysbiosis. L. acidophilus also shows various other properties such as: it is anticarcinogenic, lowers serum cholesterol level and improves lactase metabolism of host. One of the most significant property of L. acidophilous is that it modulates the immune system and can prevent various inflammatory disorders. L. acidophilous influences several immune cells such as Th17 cells and Tregs. Various studies reported that inflammation induces bone loss and leads to several bone pathologies such as osteoporosis, rheumatoid arthritis and periodontitis. Recent studies have shown the potential of probiotics in preventing inflammation mediated bone loss. L. acidophilous is one of these probiotics and is found capable in inhibition of various bone disorders. L. acidophilous restores the dysregulated immune homeostasis and prevents inflammatory bone loss. Thus, L. acidophilous can be a potential therapeutic for the management of various bone pathologies. In this book chapter we reviewed various immunomodulatory properties of L. acidophilous along with its efficacy in preventing dysbiosis and maintaining gut permeability. We also discussed the potential role of L. acidophilous as a therapeutic for the management of inflammation induced bone disorders.","PeriodicalId":121856,"journal":{"name":"Acidophiles - Fundamentals and Applications [Working Title]","volume":"330 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116123769","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}
