Slow growing bacteria
Webb23 apr. 2024 · If slow-growing bacteria are more susceptible, the population wave advances far into the inhibitory zone, leaving a trail of dead bacteria in its wake. In contrast, if fast-growing bacteria are more susceptible, the wave is blocked at a much lower concentration of antibiotic, but a large population of live bacteria remains behind the front. WebbAbstract. Commonly used culture systems, e.g., batch culture and the chemostat, work poorly for defining the behavior of slowly growing bacteria, i.e., cultures with mass …
