Using the opportunistic human pathogen\n            <jats:italic>Pseudomonas aeruginosa<\/jats:italic>\n            , we show that increasing the number density of bacteria, on agar containing aminoglycoside antibiotics, can non-monotonically impact the survival of antibiotic-resistant mutants. Notably, at high cell densities, mutant survival is inhibited. A wide range of bacterial species can inhibit antibiotic-resistant mutants. Inhibition results from the metabolic breakdown of amino acids, which results in alkaline by-products. The consequent increase in pH acts in conjunction with aminoglycosides to mediate inhibition. Our work raises the possibility that the manipulation of microbial population structure and nutrient environment in conjunction with existing antibiotics could provide therapeutic approaches to combat antibiotic resistance.\n          <\/jats:p>","DOI":"10.1098\/rsif.2015.0018","type":"journal-article","created":{"date-parts":[[2015,5,13]],"date-time":"2015-05-13T09:00:08Z","timestamp":1431507608000},"page":"20150018","update-policy":"http:\/\/dx.doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["The spatial profiles and metabolic capabilities of microbial populations impact the growth of antibiotic-resistant mutants"],"prefix":"10.1098","volume":"12","author":[{"given":"Karishma S.","family":"Kaushik","sequence":"first","affiliation":[{"name":"Department of Molecular Biosciences, University of Texas, Austin, TX 78712, USA"},{"name":"Center for Nonlinear Dynamics and Department of Physics, University of Texas, Austin, TX 78712, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nalin","family":"Ratnayeke","sequence":"additional","affiliation":[{"name":"Center for Nonlinear Dynamics and Department of Physics, University of Texas, Austin, TX 78712, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parag","family":"Katira","sequence":"additional","affiliation":[{"name":"Center for Nonlinear Dynamics and Department of Physics, University of Texas, Austin, TX 78712, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vernita D.","family":"Gordon","sequence":"additional","affiliation":[{"name":"Center for Nonlinear Dynamics and Department of Physics, University of Texas, Austin, TX 78712, USA"},{"name":"Institute of Cellular and Molecular Biology, University of Texas, Austin, TX 78712, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2015,6,6]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1586\/ecp.10.46"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1208747"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2007.0640"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1117716109"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.109.088101"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0032118"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0036313"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.26.1.42"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkn554"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1128\/mBio.00202-10"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1309729110"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.mi.49.100195.003431"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.122.1.219"},{"key":"e_1_3_3_15_2","first-page":"1811","article-title":"Aminoglycosides: a practical review","volume":"58","author":"Gonzalez US","year":"1998","journal-title":"Am.
