Combining microdilution with MicroResp™: Microbial substrate utilization, antimicrobial susceptibility and respiration

► A modified MicroResp™ system is introduced. ► It allows studying effects of compounds and mixtures on microbial growth in microplates. ► An indicator plate facilitates assessment of the respiration of the microbial strain. ► Dose-response effects are explored by curve fitting of various hormetic non-linear models.
