Sistema microbiológico de cinco bioensayos para la detección de residuos de antibióticos
Five-assay microbiological system for the screeningf antibiotic residues

Rev. argent. microbiol; 51 (4), 2019
Abstract A novel microbiological system in microtiter plates consisting of five bioassays is presented for the detection and classification of antibiotic residues in milk. The bioassays were optimized for the detection of beta-lactams (Bioassay B: Geobacillus stearothermophilus), macrolides (Bioassay M: ...
