Collection:
| Collection ID: | CO001483 |
| Collection Summary: | P. aeruginosa isolates were collected from 81 individuals with cystic fibrosis, and obtained from Seattle Children's Hospital Cystic Fibrosis Isolate Core. Bacterial isolates were stored as pure glycerol stocks at -70 degrees Celsius. |
| Sample Type: | Bacterial cells |
Treatment:
| Treatment ID: | TR001503 |
| Treatment Summary: | Liquid cultures of lysogeny broth (Lennox) were inoculated with P. aeruginosa from pure glycerol stocks and incubated aerobically at 37 degrees Celsius for 24 hours in triplicate. Cultures were centrifuged through a 0.2 µm filter to remove cells, and filtrates were transferred to GC headspace vials. |
Sample Preparation:
| Sampleprep ID: | SP001496 |
| Sampleprep Summary: | Filtrate samples were heated to 50 degrees Celsius with agitation, and volatiles were sampled for 10 minutes using solid-phase microextraction (SPME) and analyzed using comprehensive gas chromatography coupled to time-of-flight mass spectrometry. |
| Processing Storage Conditions: | Described in summary |
| Extraction Method: | Solid-phase microextraction (SPME) |
