Collection Summary: | After 18h of culture, the sample pellet was isolated. The bacterial pellets harvested from 50 mL of broth culture were mixed with 1.2 mL 80% ice-cold methanol (added to internal standard 0.001mg/ml 4-chloro-DL-phenylalanine), then vortexed for 30 s, and placed on dry ice for 30 min. The samples were centrifuged at 18000 × g for 15 min at 4 °C. The frozen samples were ground with beads and the homogenates were centrifuged at 18000 × g for 15 min at 4 °C. The supernatant was mixed with 800μL ice-cold acetonitrile, and then left to stand for 20 minutes in an ice bath. After centrifugation at 18000 × g 4℃ for 15 min, the supernatant was removed and filtered through 0.22μm membrane. |
