ABSTRACT
In mineral salts medium, supplementing with betaine in combination with increased production of endogenous osmoprotectant from a second copy of the trehalose biosynthetic genes (otsBA) improved growth of E. coli and increased the MIC for xylose, glucose, sodium lactate and NaCl. With these compounds, this combination was more effective than either betaine or trehalose alone. With succinate, this combination was no more effective than betaine alone. Neither approach improved tolerance to ethanol. A combination of betaine and increased trehalose may improve strain productivity for many bioproducts by promoting growth in the presence of high sugar concentrations.
