Do bacteria in batch culture follow four growth phases
Question asked:
“When bacteria are cultivated in a closed system, such as a batch culture, they typically exhibit a characteristic growth curve comprising four distinct phases: lag, exponential, stationary, and death.”
Summary
In batch (closed) bacterial cultures, growth follows a characteristic curve with four sequential phases: lag, exponential (log), stationary, and death (decline). This pattern is consistently described in microbiology literature.

NO2− is then rapidly decomposed via NO to N2O to become N2, which is safe for bacteria (Ruan et al., 2020, Chaudhari et al., 2017). Through analysis of experimentally measured data with our current model, the detailed growth dynamics of P. balearica were revealed. It was also found that P. balearica rapidly degraded products during the stationary phase, which was not anticipated in the previous study.
