Detailed explanation-1: -The bacterium Escherichia coli can divide every 20 min in the laboratory under aerobic, nutrient-rich conditions.
Detailed explanation-2: -Literature states that a generation time of E. coli at optimal conditions amount to 20 min [38], which corresponds to the generation time of the negative control observed in this study. As expected, generation times were mostly increasing with increased tannin concentrations.
Detailed explanation-3: -In E. coli a single round of genome replication lasts about 40 min and it must be accomplished about 20 min before cell division. To achieve such fast growth rates bacteria perform multiple replication rounds simultaneously. As a result, when the division time is as short as 20 min E.
Detailed explanation-4: -One cells takes 80 minutes to form 16 cells. If 2 cells undergoes division simultaneously, it take 160 minutes (2 hours 40 minutes) to form 32 cells. Step by step video & text solution for Given that the average duplication time of E. coli is 20 minutes.
