Abstract Bioremediation using plants and microorganisms effectively mitigates heavy metal soil contamination improves conditions. Phytoremediation with leguminous rhizobacteria enhances bioavailability promotes plant growth. This study evaluates microbial community structure in soils varying concentrations of tailings from the Fundão Dam disaster Mariana, MG, Brazil. Microbial diversity was measured by fluorescent situ hybridization treatments different presence Leucaena leucocephala. Higher proportions reduced bacterial densities, pure ore (T100%) showing lowest bacteria percentage. However, after 14 months leucaena cultivation, this treatment had highest number prokaryotes. The modified densities Bacteroidetes Pseudomonas genus. Experimentation time influenced Actinobacteria, Acidobacteria, Firmicutes. interaction between legume sampling altered density Proteobacteria Gallionella ferruginea. results show that iron impact rhizosphere, offering insights for bioremediation strategies to restore quality mining-affected areas.

The application of beneficial microbial consortium can effectively improve plant disease resistance and its growth. Various fungi were compounded with Bacillus velezensis LJ02 applied to watermelon plants in this paper. results showed that the T2 (compounded Aspergillus aculeatus 9) control gummy stem blight powdery mildew watermelon, while effect reached 83.56% 70.93%, respectively (p < 0.05). Compound treatment improved diversity richness rhizosphere community structure, relative abundance Caulobacterales Xanthomonadaceae significantly increased after applying soil. Meanwhile, internode length was decreased 28% 0.05), maximum leaf 10.33% In addition, delays maturity vegetables. By studying effects on seedlings, our study provides a theoretical basis for popularization compound inoculant.

Mine-tailing dumps are one of the leading sources environmental degradation, often with public health and ecological consequences. Due to complex ecosystems generated, they ideal sites for exploring bacterial diversity specially adapted microorganisms. We investigated concentrations trace metals in solid copper (Cu) mine tailings from Ovejería Tailings Dam National Copper Corporation Chile used high-throughput sequencing techniques determine microbial community using 16S rRNA gene-based amplicon sequence analysis. The detected were highest following order: iron (Fe) > Cu manganese (Mn) molybdenum (Mo) lead (Pb) chromium (Cr) cadmium (Cd). Furthermore, analysis identified 12 phyla, 18 classes, 43 orders, 82 families, 154 genera at three sampling points. phylum Proteobacteria was most dominant, followed by Chlamydiota, Bacteroidetes, Actinobacteria, Firmicutes. Genera, such as
