## 2 Microbiome-Based Interventions for Ecosystem Sustainability
### Successful Environmental Microbiome Projects  
Several successful projects integrating microbiome-based interventions into environmental damage management have demonstrated the significant potential of bioremediation and phytoremediation techniques. Microbial communities, which reside both internally and externally on plants, play diverse and crucial ecological roles, contributing to the effectiveness of these remediation strategies. One example is the microbial response to the _Deepwater Horizon_ oil spill in the Gulf of Mexico, where naturally occurring hydrocarbon-degrading bacteria such as _Alcantivorax_ and _Pseudomonas_ helped to degrade oil components, thereby facilitating faster recovery of the marine ecosystem [27]. The use of these microbes highlights the role of microbial diversity in bioremediation, whereby microbial metabolism of hydrocarbons converts them into less toxic substances that are easier to process by the biogeochemical cycle. A deeper analysis of the _Deepwater Horizon_ case reveals that microbial taxa such as _A. borkumensis_ and _Cycloclasticus_ were enriched in oil-contaminated zones. Metagenomic data indicated the upregulation of genes linked to hydrocarbon degradation (alkB, CYP153). Comparatively, a study by [PERSON] et al. [41] found similar microbial patterns in the Ixtoc I oil spill, suggesting conserved functional adaptations among marine microbiomes. Furthermore, nutrient enrichment strategies, including nitrogen and phosphate amendments, significantly accelerated biodegradation in both cases, underscoring the synergy between microbial consortia and nutrient availability in bioremediation. This case is in line with the findings of [PERSON] et al. [27], who highlight the significance of microbial biodiversity in marine ecosystems for maintaining resistance to environmental perturbations, especially in regions directly affected by oil exploration and spills. Another success story comes from the Perez Zeledon landfill in Costa Rica, where bioremediation was used for the treatment of leachate, a highly contaminated liquid made by the decomposition of waste [42]. This leachate can reach underground water tables or even the sea, covering large areas with pollutants. In the project, microbial consortia helped reduce the concentration of the pollutants, improving water quality and decreasing environmental impact. This shows how microbial communities can be used in waste management to deal with complex environmental problems such as leachate from landfills, which represents an important threat to water quality. In parallel to the Perez Zeledon landfill project, [PERSON] et al. [42] published an article on the role of microbial interventions in waste sanitation and environmental management. Lastly, microbiome-assisted phytoremediation in contaminated agricultural soils is another successful example of microbiome-based intervention. _Sedum alfredii_ and its microbiome were used for the remediation of heavy metals (cadmium and zinc) in polluted soils to reduce soil toxicity and produce safe crops [43]. This also demonstrates the emerging trend of combining plants with a microbial community for sustainable remediation efforts. As described by [PERSON] et al. [43], phytoremediation systems are highly effective and economical. Microbiome-assisted plant remediation can be used as a cost-effective solution for the restoration of contaminated farmlands. While microbiome interventions offer promising solutions for environmental sustainability, their long-term ecological consequences remain underexplored. For example, large-scale soil microbiome engineering could unintentionally disrupt native microbial diversity, potentially altering nutrient cycling and soil fertility over time [27]. Additionally, introducing genetically modified microbial strainsfor bioremediation may lead to the horizontal gene transfer of antibiotic-resistance genes, as observed in a decade-long monitoring study by [PERSON] et al. [44].
