Metabolic reprogramming of Pseudomonas aeruginosa by phage-based quorum sensing modulation.
resulting in decreased levels of PQS and its precursor 2-heptyl-4(1H)-quinolone. The lack of a functional PqsD enzyme impairs LUZ19 infection but is restored by external supplementation of ...
Pyrrolizidine alkaloids in herbs and related foodstuffs (PASHERBS)
available on the Belgian market. The project yielded many interesting results and highlighted a recurrent contamination of herb mixes, sometimes with very high PA s/ PANO s concentrations (ppm levels). The ...
Food contamination with pyrrolizidine alkaloids: the expected and the unexpected
has been established for more than 1,200 samples available on the Belgian market. The analytical results showed that PA s/ PANO s contamination in food is recurrent, with maximum levels ranging from ...
