Samenvatting:

The presence of a genetically modified microorganism (GMM) or its DNA, often harboring antimicrobial resis- tance (AMR) genes, in microbial fermentation products on the market is prohibited by European regulations. GMMs are currently screened for through qPCR assays targeting AMR genes and vectors, and then confirmed by targeting known specific GM constructs/events. However, when the GMM was not previously characterized and an isolate cannot be obtained, its presence cannot be proven. We present a metagenomics approach cap- able of delivering the proof of presence of a GMM in a microbial fe…
