Antibiotic effect on E. coli. a OD curves and b CFU counts of E. coli cultures exposed to solvents and antibiotics with bacteriostatic, bactericidal and cell wall affecting mode of action in a concentration of 100 μM. Antibiotics affecting the cell wall resulted in significantly decreased OD values indicating that a substantial amount of cells were lysed over time course. After an incubation time of 30 min normal CFU counts were obtained for all antibiotics
