[EN] This article presents a microbiological system composed of a " BT" bioassay (Beta-lactams and Tetracyclines) and a " QS" bioassay (Quinolones and Sulfonamides). The " BT" bioassay contains spores of Geobacillus ...
Aims: A microbiological bioassay using Geoacillus stearothermophilus was optimized to detect betalactams at concentrations near to the Maximum Residue Limits (MRLs), with low cross-specificity for tetracycline. Methods and ...
