Collection:
| Collection ID: | CO001163 |
| Collection Summary: | Replicate cultures of Acidithiobacillus ferrooxidans (American Type Culture Collection strain 23270) were grown in 1 L of Tuovinen and Kelly (1973) liquid medium ([FeSO4·7H2O] = 33.4 g/L; 0.3 % (w/v) (NH4)2SO4; MgSO4·7H2O; K2HPO4, pH 2.5). Cells were incubated on a gyratory shaker at 180 rpm and 30 °C. Cells harvested for the metabolomic comparison of two points in the growth curve were in late exponential growth phase (OD425 = 0.85) or in early exponential growth phase (OD425 = 0.65). The cells were harvested via centrifugation at 14,000 x g for 5 min at 4 °C then transferred into a 1.5 mL centrifuge tube. |
| Sample Type: | Bacterial cells |
Treatment:
| Treatment ID: | TR001183 |
| Treatment Summary: | After the cells were concentrated into a 1.5ml centrifuge tube, the cellular metabolism was quenched using 40ul of 60% MeOH and 40% H2O (v/v) with 0.85% (w/v) of Ammonium Formate, adjusted to pH 2.5 and cooled to -20 °C. The quenched cells were centrifuged for 5 minutes at 2,319 x g at 4 °C. The cells were then placed on dry ice, the cell supernatant was removed and an isopropanol:methanol:water (IMW) (3:3:2) extraction solution that was cooled to -20 °C was added. These solutions were then vigorously vortexed and then centrifuged at 15,682 x g for 10 min. The extraction liquid was then collected and placed at -80 °C until further analysis. |
Sample Preparation:
| Sampleprep ID: | SP001176 |
| Sampleprep Summary: | Immediately prior to analysis the extraction solution was evaporated to dryness and reconstituted in 80:20 Acetonitrile:Water. The samples were normalized based on Gcdw. |
