Abstract excerpt
The effect of the addition of trimethylamine N-oxide (TMAO) in the growth medium on Escherichia coli anaerobic fermentative and respiratory pathways was examined. Formate dehydrogenase H (FDH-H) activity was totally repressed by the addition of 40 mM TMAO, whereas the overall hydrogenase (HYD) ac...
