| Study Title | Investigation of age-dependent changes in the gut of honeybee workers using targeted metabolomics for SCFA determination |
| Study Summary | To determine changes in the metabolic activity of the gut microbiota, we measured the concentrations of seven short-chain fatty acids (SCFA) and lactate. All SCFA showed low concentrations in newly emerged workers. We found that acetate, propionate and butyrate are the main SCFA in the honeybee gut and peak in 5-day old and in-hive workers. Lactate showed an inverse trend with highest concentrations in 1-day old workers and a significant decrease on all subsequent days (Kruskal Wallis test, p <0.05). |

| Collection Summary: | Workers were pooled to obtain a final sample number of n = 5. The brain(s) and gut(s) from the same workers were assigned the same sample names. In total, we had 15 samples from each age group, with the exception of the foraging stages, where owing to the lack of foragers from Hive 1, we only had 11. All sampled bees were placed directly in liquid nitrogen to prevent changes in the metabolic profile. They were then decapitated in the laboratory so that the head and body of each bee were kept in a separate Eppendorf tube (Eppendorf, Germany) for later dissection. Worker guts were dissected on Petri dishes. Sternite 6 and the stinger apparatus were gently pulled using tweezers, which allowed extraction of the entire gastrointestinal tract. The stinger apparatus and venom sac were carefully excised and the honey crop was removed. |
