摘要：

The aim of this study was to assess the effect of Pseudomonas fluorescens (P) application on isofetamid (IS) dissipation; the number of specific genes of archaea, bacteria and ammonia-oxidizing bacteria (AOB); and the activity of beta-Glucosidase, phosphomonoesterase, N-acetyl-glucosaminidase and arylsulfatase. It was observed that the IS concentration was lower in the P+IS than in IS throughout the entire study period, which indicates the potential of P. fluorescens to decompose isofetamid faster. IS+P application significantly influenced N-acetyl-glucosaminidase, arylsulfatase and phosphomonoesterase activity in soil compared to the control by approximately 29%, 72% and 6.5%, respectively. Moreover, it was observed that on day 21 in IS+P, the number of bacterial genes was significantly higher than in the control and IS and than on day 1, by 10% and 20%, respectively. On day 21, the number of archaea was significantly higher in all variants and ranged from 3.61 (control) to 6.88 log10 gene copies/g dm (IS+P). Correlation analysis showed a positive correlation between IS and TOC, while there was a negative correlation between IS and beta-Glu and the number of archaea and AOB genes. The tested strain has the potential to be a biofertilizer and an agent in the bioremediation of contaminated soils.
