[Demonstration of hormonal actions on Escherichia coli K 12 by potentiometry in the presence of lipoic acid; correlation with measurements of microbial growth and glucose consumption].
The action of hormones on Escherichia coli K 12 was followed by potential-time measurements in the presence of lipoic acid (LA), photometric determinations of growth and glucose titrations. Bovine growth hormone (5 to 60 IU/1) increased O2 consumption. The (10 IU/1) insulin-facilitated transport of LA was stimulated by glucose. Adrenaline (0.5 to 15 mg/l) increased more glucose and O2 consumption than growth.
