| Abstract: |
| Soil organic matter(SOM), especially relatively stable organic matter, is a critical factor in controlling the sorption and sequestration of pollutants, particularly organic contaminants. Organic matter products produced by microorganisms are called organic carbon in the"microbial carbon pump"(MCP)process, which plays a significant role in the stable carbon pool. This contradicts the traditional view that the stable carbon pool is dominated by the complex molecular structures of plant derivatives. Therefore, understanding the mechanism of organic carbon stability under the action of the MCP and its interaction with pollutants has become a new challenge for environmental geoscience research. This paper reviewed the compositions, properties, and stabilization mechanism of microbial-derived carbon, as affected by different microbial communities and mineral properties. In addition, the interaction between stable organic carbon and pollutants in the MCP process was emphasized. Finally, we proposed several research prospects for SOM stabilization in the future, providing new ideas for improving soil carbon sequestration capacity, realizing carbon sequestration and emission reduction measures, and aiding soil pollution remediation and governance. |
