To elucidate the physiological adaptation of Escherichia coli due to cra gene knockout, a total of 3,911 gene expressions were investigated by DNA microarray for continuous culture. About 50 genes were differentially regulated for the cra mutant. TCA cycle and glyoxylate shunt were down-regulated, while pentose phosphate (PP) pathway and Entner Doudoroff(More)
BACKGROUND Most bacteria can use various compounds as carbon sources. These carbon sources can be either co-metabolized or sequentially metabolized, where the latter phenomenon typically occurs as catabolite repression. From the practical application point of view of utilizing lignocellulose for the production of biofuels etc., it is strongly desirable to(More)
The metabolism of Gluconacetobacter oboediens was investigated in relation to different carbon sources for the continuous cultures at the dilution rate of 0.05 h−1. The 13C-flux result implies the formation of metabolic recycles for the case of using glucose and acetate as carbon sources. When glucose and ethanol were used as carbon sources, the specific(More)
