Currently, bioremediation employing microorganisms is garnering significant interest due to its effectiveness. The present investigation aimed to isolate actinobacterial strains from an Italian mine and to characterise them for heavy metals resistance and plant growth-promoting characteristics. The different samples were processed for DNA extraction and 16S rRNA gene metabarcoding to investigate the bacteria and archaea communities. Cultivable microbiota were isolated and evaluated for heavy metals tolerance and different PGP traits. The most pertinent strains were tested for compatibility, merged into a consortium, and tested on Lemna minor L. Metabarcoding analysis revealed that amplicon sequence variants (ASVs) at the phylum level were mostly assigned to proteobacteria and bacteroidota. Uncultured and unknown taxa were the most prevalent in the samples at the genus level. A total of ten strains were obtained from the culture-dependent approach exhibiting interesting heavy metals tolerance and plant growth-promoting traits. The best strains (MTW 1 and MTW 5) were selected and further characterised by 16S barcoding. These strains were identified as Streptomyces atratus (99.57% identity). An in planta experiment showed that the metal-tolerant consortium MTW 1-5 improved plant physiology by significantly optimising plant growth and tolerance to heavy metals. The experiment conducted provided evidence for the possibility of using actinobacteria as bioaugmentation agents to improve the phytoextraction abilities of L. minor.<\/jats:p>","DOI":"10.3390\/plants14223467","type":"journal-article","created":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T12:57:13Z","timestamp":1763038633000},"page":"3467","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Microbial Consortium of Streptomyces spp. from Mining Environments Enhances Phytoremediation Potential of Lemna minor L."],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9614-1956","authenticated-orcid":false,"given":"Rihab","family":"Djebaili","sequence":"first","affiliation":[{"name":"Department of Life, Health and Environmental Sciences, University of L\u2019Aquila, Via Vetoio 1, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4202-0352","authenticated-orcid":false,"given":"Beatrice","family":"Farda","sequence":"additional","affiliation":[{"name":"Department of Life, Health and Environmental Sciences, University of L\u2019Aquila, Via Vetoio 1, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9201-8895","authenticated-orcid":false,"given":"Oscar","family":"Gialdini","sequence":"additional","affiliation":[{"name":"Department of Life, Health and Environmental Sciences, University of L\u2019Aquila, Via Vetoio 1, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria","family":"Vaccarelli","sequence":"additional","affiliation":[{"name":"Molecular Ecology Group (MEG), Water Research Institute (IRSA), National Research Council (CNR), Corso Tonolli 50, 28922 Verbania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1060-0264","authenticated-orcid":false,"given":"Younes","family":"Rezaee Danesh","sequence":"additional","affiliation":[{"name":"Department of Plant Protection, Faculty of Agriculture, Van Yuzuncu Yil University, Van 65090, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0073-9935","authenticated-orcid":false,"given":"Marika","family":"Pellegrini","sequence":"additional","affiliation":[{"name":"Department of Life, Health and Environmental Sciences, University of L\u2019Aquila, Via Vetoio 1, 67100 L\u2019Aquila, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"789","DOI":"10.1016\/j.scitotenv.2018.06.094","article-title":"Urbanization Strategy and Environmental Changes: An Insight with Relationship between Population Change and Fine Particulate Pollution","volume":"642","author":"Han","year":"2018","journal-title":"Sci.
