Metabarcoding: 16S V3V4. 10^0 CFU Salmonella-spiked chicken feed enriched overnight in BPW
DNA extracted with DNeasy PowerSoil Pro Kit (Qiagen). V3-V4 variable regions amplified by PCR with primers 341F-785R (Klindworth 2013) and sequencing libraries were prepared according to the 16S Metagenomic Sequencing Library Preparation protocol.
