Rhizosphere microbiome engineering with PGPR to combat soil-mediated climate change
AI summary Read the abstract
This review pulls together existing research on beneficial soil bacteria that help plants grow while also cleaning up polluted soil, breaking down heavy metals, microplastics, and other contaminants, and locking more carbon into the ground instead of the atmosphere. This matters because healthier soil means safer, more nutritious food and fewer harmful pollutants working their way up the food chain to us, all while helping fight climate change. The authors also suggest combining these soil bacteria with AI and smart sensors to make this approach more reliable for farms in the future.
The synergistic effects of accelerated climate change and anthropogenic land-use shifts increasingly compromise the functional integrity of terrestrial ecosystems. To preserve soil health and ensure global food security, a transition toward biointensive, climate-smart agriculture is imperative. This review provides a comprehensive synthesis of the multifaceted role of plant growth-promoting rhizobacteria (PGPR) as “rhizosphere architects,” bridging global biogeochemical cycles with intricate molecular and digital interventions. Microbe mediated mitigation of atmospheric stressors is evaluated by monitoring increases in soil carbon sequestration and concomitant reductions in greenhouse gas (GHG) emissions. Central to ecosystem recovery is the physiochemical regeneration of marginal and polluted soils, where PGPR facilitate the detoxification of xenobiotics, including heavy metals, microplastics, and organic contaminants, while promoting the structural restoration of degraded edaphic environments. At the tripartite plant-microbe-soil interface, the synergistic regulation of root system architecture (RSA) is investigated alongside the emerging role of epigenetic modifications, such as DNA methylation and histone acetylation, as critical drivers of transgenerational stress memory against extreme climatic conditions. These molecular and structural shifts are functionally correlated with rhizosphere enzymatic activity, including specific enzyme fluxes (e.g., urease, phosphatase, and dehydrogenase), which serve as biochemical proxies for soil health restoration. To address the historical inconsistency of field inoculants, a translational framework is proposed that integrates Industry 4.0 technologies, such as AI-assisted bioformulation design and IoT-based precision monitoring, for real-time microbiome management. By discussing the translational hurdles of microbial competition and regulatory frameworks, this synthesis underscores how the fusion of microbial ecology and digital agriculture provides a robust pathway toward resilient terrestrial ecosystems and sustained agricultural productivity in the Anthropocene.

Rhizosphere Engineering for the Degradation of Recalcitrant Xenobiotic Contaminants from Agricultural Soils
AI summary Read the abstract
This review paper looks at how the zone around plant roots (called the rhizosphere) uses natural bacteria and fungi to break down stubborn pollutants in farm soil—things like pesticides, industrial chemicals, and even microplastics. This matters because these contaminants can build up in crops and eventually end up in our food, so harnessing these natural soil cleanup processes could mean safer produce and healthier soil for growing our food long-term. The authors summarize existing research on how this works rather than presenting new experiments, and point to future tools that could help farmers use these natural cleanup crews more effectively.

This review examines how rhizosphere bioengineering — manipulating plant-microbe interactions — can promote plant growth and soil health under climate change conditions including elevated temperature, drought, and pollution stressors such as microplastics.
Microbial and multi-omics approaches for bioremediation of emerging contaminants: environmental impact and future engineering solutions
AI summary Read the abstract
This research review summarizes how scientists are using helpful microbes (bacteria, fungi, and algae) to clean up dangerous pollutants in our water and soil, including pharmaceuticals, pesticides, and microplastics that can harm human health. The study shows that these tiny organisms can naturally break down and remove many toxic chemicals from the environment. This matters because it could lead to cheaper, eco-friendly ways to clean up contaminated areas and protect our drinking water and food supply.
Green technologies for soil remediation: a systematic review
AI summary Read the abstract
Soil pollution from things like heavy metals, oil residues, microplastics, and pesticides doesn't just hurt the environment, it can work its way into the food we grow and eat, potentially raising risks of cancer and other health problems. This review rounds up existing research on eco-friendly cleanup methods, like using special plants, charcoal-like soil additives, and natural minerals to soak up or break down these toxins without harsh chemicals. The takeaway: safer, greener ways to clean contaminated soil already exist and could help protect both farmland and the safety of our food supply.
