| Abstract | ||
| A total of 50 P. aeruginosa isolates are leading reasons of hospital acquired infections (burns) were collected from AL-Kindy Hospital. This study focused on the quick synthesis of silver nanoparticles by this bacteria as assay for periplasmic nitrate reductase enzyme. The silver nanoparticles were described by using Atomic Force Microscopy (AFM) and found the average size was 93.55nm. From the screening profile of 50 isolates enlisted in this study the percent of napA gene positive encoding periplasmic nitrate reductase was 100%. Results revealed that nitrogen bases sequencing for PCR product of one isolate correspond reaching up to 88% as compared with nitrogen base sequence of the napA gene of P. aeruginosa strain of National Center for Biotechnology Information (NCBI). | ||
