Treatment:

Treatment ID:	TR002927
Treatment Summary:	All samples were initially inoculated with a mixed culture of L. kefiri and L. kefiranofaciens inoculum blended from 3-day cultures. 20 mL MRS medium was inoculated with 0.5 mL of the combined inoculum and incubated for 3 days, one set of 10 at 30°C, and another set of 10 at 37°C. For controls, L. kefiri and L. kefiranofaciens were inoculated in triplicate for each temperature. The tubes were removed from the incubator after 3 days, and 0.1 mL of each sample was placed in a 96 well plate for OD (600 nm) analysis. Samples were then centrifuged (3000×g, 4°C, 10 min), and the supernatant was removed and frozen for further analysis. The pellet was washed in fresh MRS (pH 5.5), divided in three aliquots, re-pelleted in microcentrifuge tubes, and frozen at -80°C for subsequent metabolomic analysis.
