Dynamics of glucose-lactose diauxic growth in E. coli
We present a mathematical model of glucose-lactose diauxic growth in Escherichia coli including both the positive and negative regulation mechanisms of the lactose operon as well as the inducer exclusion. To validate this model, we first calculated the time evolution of βgalactosidase for only the lactose nutrient and compared the numerical results with experimental data. Second, we compared th...
متن کاملBacterial gene regulation in diauxic and non-diauxic growth.
When bacteria are grown in a batch culture containing a mixture of two growth-limiting substrates, they exhibit a rich spectrum of substrate consumption patterns including diauxic growth, simultaneous consumption, and bistable growth. In previous work, we showed that a minimal model accounting only for enzyme induction and dilution captures all the substrate consumption patterns [Narang, A., 19...
متن کاملDiauxic Growth of Azotobacter vinelandii on Galactose and Glucose: Regulation of Glucose Transport by Another Hexose.
The growth curve of Azotobacter vinelandii was biphasic when the organism was grown in a medium containing a mixture of galactose and glucose. Galactose was the primary carbon source; glucose was also consumed, but the rate at which it was consumed was lower than the rate at which galactose was consumed during the first phase of growth. Metabolic pathways for both sugars were induced. Cell cult...
متن کاملDIAUXIC GROWTH OF Geotrichum candidum AND Penicillium camembertii ON AMINO ACIDS AND GLUCOSE
The purpose of this work was to examine physiological differences between the yeast Geotrichum candidum and the mould Penicillium camembertii, organisms involved in the industrial process of cheese ripening. Three groups of amino acids had previously been characterized, based on their carbon assimilation and dissimilation by the two fungal species. For both of them, a diauxic growth phase had b...
متن کاملAlteration of glucose transport and diauxic growth in 5-thio-D-glucose-resistant mutants of Azotobacter vinelandii.
Spontaneous mutants of Azotobacter vinelandii defective for glucose utilization were selected as resistant to 5-thio-D-glucose. Mutant strains AM2, AM38, and AM39 exhibited longer generation times than the wild type when grown on glucose. Mutant strain AM2 also exhibited an altered Km and Vmax for glucose uptake. During acetate-glucose diauxie, glucose utilization in the 5-thio-D-glucose-resist...
