Study TitleMetabolic Adaptations of Microbacterium sediminis YLB-01 for Survival in the Challenging High-Pressure of the Deep Sea
Study SummaryBy using NMR-based metabolomic analysis, we investigated the metabolic adaptations of Microbacterium sediminis YLB-01 in response to high-pressure conditions. We recorded the 600 MHz 1D 1H-NMR spectra on aqueous extracts from YLB-01 cells, and then assigned resonances of 31 metabolites. The distinct metabolic separation between the HPLT and NPLT groups highlighted the significant effect of high-pressure treatment on the metabolism of YLB-01 cells.

Sample Preparation:

Sampleprep ID:SP002917
Sampleprep Summary:After culturing the YLB-01 cells, each 100 mL of the culture was transferred into a 250-mL centrifuge bottle and centrifuged at 4°C (6000 g, 5 min). The supernatant was carefully decanted, and the cell pellets were rapidly cooled to -40°C using 100 mL of a buffer composed of a 3:2 methanol/water mixture containing 0.85% (wt/vol) NaCl. The mixture was centrifuged again at 4°C (6000 g, 5 min). The cell pellets were washed three times with 5 mL of cold phosphate-buffered saline (PBS) and centrifuged at 4°C (6000 g, 5 min) after each wash. Finally, the cell pellets were stored at -80°C until further use. Initially, 600 μL of a cold extraction buffer consisting of a 1:1 mixture of distilled water and acetonitrile was added to homogenize the samples. The mixtures were then sonicated on wet ice for 180 cycles, with each cycle consisting of 2 seconds of ultrasound followed by a 3-second pause. After centrifugation at 4°C (12000 g, 10 min), the supernatants were collected and lyophilized, resulting in an extract powder that was stored at -80°C for further analysis.
