Study TitleTranscriptomic and lipidomic analysis unravels the response of Faecalibacterium prausnitzii to calcium palmitate
Study SummaryInfant formula is a suggested alternative to human milk if breastfeeding is not an option; vegetable oil blends are commonly used in infant formula (IF) to replace dairy fat, which can induce the formation of the poorly soluble soap calcium palmitate (CP) in the infant’s gut. Previously, we observed that CP at a low concentration of 0.01 mg/ml inhibits the growth of dominant infant bacteria such as Faecalibacterium prausnitzii both during the exponential phase as well as in the stationary phase. Here, we investigate the underlying mechanism of the CP inhibition on infant-gut bacteria using F. prausnitzii as a model by analysing its growth at a transcriptomic and lipidomic level.

Collection:

Collection ID:CO002061
Collection Summary:Lipids were extracted using the MTBE method (Gil et al., 2018). The bacterial cell pellet was resuspended into 75 μL water, then it was incubated with 200 μL methanol and 625 μL MTBE (methyl tert-butyl ether) for 1 h on a shaker. The bacteria/methanol/MTBE mixture was further incubated with 100 μL water to induce phase separation. After 10 min centrifugation at 1000 × g, the upper organic phase was collected. The lower phase was re-extracted with 250 μL MTBE/methanol/water 10:3:2.5 v/v/v and incubated on a shaker for 30 min. After 3 min centrifugation at 1000 × g, the upper organic phase was collected. The combined organic phases containing the lipids were dried in a vacuum centrifuge at 30 ºC and then dissolved in 25 μL CHCl3/methanol/water 60:30:4.5 v/v/v. 75 μL isopropanol/acetonitrile/water 2:1:1 v/v/v was added to dilute the lipid solution.
Sample Type:Bacteria
Collection Location:University Medical Center Groningen (UMCG)

Treatment:

Treatment ID:TR002080
Treatment Summary:The diluted lipid solution was separated using a Zorbax Eclipse Plus C18 column (1.8 μm, 50 × 2.1 mm) on an Acquity UPLC system (Waters, Manchester, UK). Mobile phases consisted of 10 mM ammonium formate in water/acetonitrile/formic acid 2:3:0.005 v/v/v (eluent A) and 10 mM ammonium formate in isopropanol/acetonitrile/formic acid 9:1:0.01 v/v/v (eluent B). Linear gradient elution was as follows: 0– 2 min from 40 to 43% eluent B, 2–12 min from 50 to 54% eluent B, 12-18 min from 70 to 99% eluent B, and 18–20 min 40% eluent B.. The column temperature was set at 55 °C, and the flow rate was 0.4 mL/min. One μL of sample was loaded to MaXis plus high-resolution QTof mass spectrometer (Bruker, Bremen, Germany), Lipids were detected by electrospray ionization in positive (ESI+) and negative mode (ESI-).

Sample Preparation:

Sampleprep ID:SP002074
Sampleprep Summary:F. prausnitzii A2-165 (DSM 17677) was inoculated in YCFAG medium (Lopez-Siles et al, 2012), without (CP0) and with 0.01 mg/mL CP (CP2) (Wang et al., 2021) in an anaerobic chamber (80% N2, 12% CO2, and 8% H2) and incubated in the same chamber at 37°C.
