Hypothesis
Inoculation with strain PM1 will reduce selenium contamination and promote soil ecological stability by increasing microbial diversity.
Conclusion
Strain PM1 significantly enhances sodium selenite degradation and mitigates its negative effects on soil microbial communities.
Supporting Evidence
- Sodium selenite significantly reduced microbial diversity and altered community composition.
- Inoculation with strain PM1 partially reversed the negative effects of sodium selenite.
- Strain PM1 enhanced the complexity of microbial co-occurrence networks.
- Stochastic processes dominated the assembly of bacterial communities under selenium stress.
Takeaway
This study shows that a special bacteria can help clean up selenium pollution in soil, making it healthier for plants and animals.
Methodology
High-throughput 16S rRNA gene sequencing was used to analyze soil samples treated with sodium selenite and strain PM1.
Limitations
The study was conducted under controlled laboratory conditions, which may not fully replicate field environments.
