本研究では、炭素固定菌株Bacillus cereus SRを担持したバイオ炭が、土壌有機炭素（SOC）含有量を36.38%～136.34%増加させ、CO2排出を削減することを示した。500℃で調製したバイオ炭は持続的にSOCを増加させる可能性があり、微生物群集の共生関係を強化した。これらの結果は、微生物ベースのバイオ炭によるSOC隔離の改善に理論的基盤を提供する。
English
This study demonstrates that biochar loaded with carbon-fixing bacterium Bacillus cereus SR increases soil organic carbon (SOC) by 36.38% to 136.34% and reduces CO2 emissions. The 500°C biochar variant sustainably enhances SOC and improves microbial community symbiosis. These findings provide a theoretical basis for microorganism-based biochar in SOC sequestration improvement.

📄 Abstract（原文）
Microorganism-based biochar has been mainly used for plant growth promotion and pollution management, but its role in soil fertility has been neglected. In this study, we used biochar loaded with Bacillus cereus SR, a carbon-fixing strain, to achieve a stable inoculation and increase soil organic carbon (SOC) content. Compared with the control group, microorganism-based biochar was more effective in increasing SOC content and reducing CO2 emissions, with SOC content increasing by 36.38% to 136.34%. Biochar treatment alone inhibited soil enzyme activities but biochar carrying Bacillus cereus SR alleviated the inhibitory effect. The 500 °C strain-containing biochar exhibits the potential to sustainably increase SOC, as its ribulose-1,5-bisphosphate carboxylase/oxygenase enzyme activity was 53.38% and 45.77% higher than the control group on the 24th and 63rd days, respectively. This phenomenon may be attributed to the moderate available organic carbon content of 500 ℃ biochar. Microorganism-based biochar increased the abundance of Firmicutes, Bacilli, Bacillaceae, Bacillales, and Bacillus at each taxonomic level. These modifications enhanced symbiotic relationships and community stability among soil bacteria. These results provide a theoretical basis for the application of microorganism-based biochar in improving SOC sequestration.
