Diauxic growth e coli

WebDiauxic Growth Diauxic growth is a diphasic growth represented by two growth curves intervened by a short lag phase produced by an organism utilizing two different substrates, one of which is glucose. When E. coli grows in a medium containing both glucose and lactose, it uses glucose preferentially until the glucose is exhausted. WebThe following shows the dauxic growth curve when E. coli are grown in a mixture of glucose and lactose. - Lactose used Short lag phase Bacterial density Glucose used Time (hours) FIG. 19.3. Diauxic or diphasic growth curve of E. coli grown with a mixture of glucose and lactose. Glucose is first used, then lactose.
