| Discovery Information | |
| Isolation Host | Arthrobacter globiformis NRRL B-4425 |
| Found By | Sarah Sadat |
| Year Found | 2025 |
| Location Found | Ottawa, Canada |
| Finding Institution | University of Ottawa |
| Program | Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science |
| From enriched soil sample? | No |
| Isolation Temperature | 30°C |
| GPS Coordinates | 45.42826 N, 75.6755 W Map |
| Discovery Notes | Isolated from a soil sample taken from a city-maintained flower bed on Laurier Ave E in downtown Ottawa. The bed was densely planted with seasonal flowers, suggesting nutrient-rich soil. |
| Naming Notes | The name "Mahtaab" (مهتاب), meaning "moonlight" in Farsi, was chosen to reflect the phage's emergence from the soil, a dark environment. Just as the moon provides a beacon in the night sky, this phage emerges as a new entity from the darkness. |

| Plaque Notes | The plaques are clear, circular, and approximately 2–3 mm in diameter, a morphology characteristic of a strictly lytic phage infecting A. globiformis. Their moderate size likely reflects efficient diffusion through the agar and a modest burst size relative to phages that form smaller plaques. The consistent plaque formation observed across assays suggests that Mahtaab maintains high infectivity and strong replication efficiency. |
