[The electro-optical investigation of suspensions of Escherichia coli K-12 cells metabolizing glucose, lactose, and galactose].
The electro-optical characteristics of suspensions of Escherichia coli K-12 cells metabolizing glucose, lactose, and galactose were studied my measuring the suspension turbidity as a function of cell alignment in an orienting electric field whose frequency was varied from 10 kHz to 10 MHz. In a frequency range of 10 kHz to 1 MHz, the orientational spectra of E. coli K-12 cells grown on glucose and lactose considerably changed after their incubation in the presence of the sugars. These changes likely reflect alterations in the polarizability of the cells induced by sugar metabolism.
