WebWordSense Dictionary: diauxic growth - spelling, hyphenation, synonyms, translations, meanings & definitions. WebDec 1, 2002 · When glucose becomes limiting, the cells transiently arrest growth and switch to a respiratory mode of energy production. This period of transition is known as the ‘diauxic shift’. During the subsequent post-diauxic growth period, the cells grow rather slowly and utilize the ethanol that was produced during the previous period of fermentation.

The idea behind the diauxic growth experiment (literally meaning double growth) is very simple – we put E. coli in a medium with two types of sugars, one that it can directly metabolize (for example glucose) and a second sugar
Webdiauxic growth (uncountable) ( biology ) growth of an organism that is governed by two auxins and, thus, has two phases of growth Retrieved from " … WebJan 1, 2016 · CONCLUSION The dynamic metabolic model developed for the heterotrophic diauxic growth of Chlorella sorokiniana on acetate and butyrate achieved a so far unequalled accuracy. The model efficiently fits the dynamic experimental data and correctly predicts the biomass yields for a broad range of experimental conditions.
WebKeyword: diauxic shift. Description. The switch from rapid fermentative growth in the presence of a rich carbon source to slower exponential growth by aerobic respiration using ethanol once the preferred carbon source has been exhausted.
