Abstract excerpt

Trehalose transport and metabolism in Escherichia coli are induced by trehalose in the growth medium but only at low osmolarity. In contrast, synthesis of internal trehalose as an osmoprotectant occurs only at high osmolarity, independent of the carbon source. The synthesis of internal trehalose...
