Title |
Planktonic cells - cells grown in LB 1 |
Sample type |
SRA |
|
|
Source name |
Lab culture
|
Organism |
Pseudomonas aeruginosa |
Characteristics |
strain: PAO1 cell type: Planktonic cells protocol: LB
|
Treatment protocol |
Persister cells (plusCiprolLarge) were isolated by centrifuging the culture and washing with 0.85% NaCl three times before incubating the cells with ciprofloxacin (50 µg/ml) in 0.85% NaCl (persister, plusCiproLarge) or 0.85% NaCl alone (stationary, minusCiproLarge) for 3.5 hours. Following incubation, the cells were again washed three times with 0.85% NaCl and plated on LB agar. The 18-hour culture was used to inoculate fresh LB which was incubated until the OD600 reached 0.5 (planktonic). Biofilms were formed in LB on borosilicate glass discs as described previously. Each treatment condition was performed twice.
|
Growth protocol |
An 18-hour culture of P. aeruginosa PAO1 was grown in Luria-Bertani (LB) broth at 37°C.
|
Extracted molecule |
total RNA |
Extraction protocol |
RNA was isolated from untreated and persister cells using the RNeasy Kit (QIAgen) according to manufacturer’s instructions and treated twice with TURBO DNase (Ambion, Grand Island, NY) to remove any contaminating DNA (5, 6). Ribosomal RNA was depleted using the Ribo-Zero Magnetic kit (Epicentre, Madison, WI) Directional library was generated using the NEXTflex directional RNA-seq kit (Bioo Scientific, Austin, TX)
