(A) Examples of diauxic shift phenotypes. The growth experiments executed by Eve revealed a wide variety of phenotypes: lower/faster growth rates (in fermentative/respiratory metabolism), and lower/greater growth yields. Each growth curve is made up of the mean OD₅₆₀ readings for a strain (from a minimum of eight replicates) over 45 h, vs. wild type BY4741 (WT) with paired starting culture OD values. (B) An example of a glucose metabolism phenotype. Glucose consumption takes place most rapidly during the fermentative growth phase, with glucose levels generally depleted before the second period of slower growth.
