www.reachcambridge.combacterial growth. •Only transformed bacteria that contain the plasmid and express beta-lactamase can grow on plates that contain ampicillin. Only a very small percentage of the cells take up the plasmid DNA and are transformed. Untransformed cells cannot grow on the ampicillin selection plates. Important points

assets.thermofisher.comThe standard phases of bacterial culture growth (lag, log, stationary, and death) are well documented, with the log phase recognized as the point where bacteria divide as rapidly as possible(1). Using a spectrophotometer to measure the optical density at 600 nm (OD600) of a bacterial culture to

These schemes utilize the bacterial morphology and staining properties of the organism, as well as O 2 growth requirements of the species combined with a variety of biochemical tests. For clinicians, the environmental reservoir of the organism, the vectors and means of transmission of the pathogen are also of great importance.
