초록/요약
The N2O-reducing rhizobacterium, Pseudomonas sp. M23, was isolated from maize rhizosphere soil. The maximum N2O reduction rate of the strain M23 was 15.6 mmol·g-dry cell weight-1·h-1. Its N2O reduction activity was not inhibited by diesel contaminant, and it was enhanced by the addition of the root exudates of maize and tall fescue. The remediation efficiency of diesel-contaminated soil planted with maize or tall fescue was not inhibited by inoculating with the strain M23. Root weights in the soil inoculated with the strain M23 were greater than those in the non-inoculated soil. These results suggest that Pseudomonas sp. M23 is a promising bacterium to mitigate N2O emissions during the remediation of diesel-contaminated soil. © 2023 Korean Society for Microbiology and Biotechnology. All rights reserved.
