The cell surface net charge of the bacteria was examined by microelectrophoresis, which measures zeta potentials of microorganisms in the stationary phase.
As described by Brianezi [46], the study of comets is the degree of DNA fragmentation and its migration by microelectrophoresis. Currently, this method is a widely used genotoxicity test of industrial, pharmaceutical, and agrochemical products for damage and DNA repair in individual cells.
Using laser doppler microelectrophoresis to measure zeta potential, an electric field is applied to a solution of molecules or a dispersion of particles, which then move with a velocity related to their zeta potential.

The [zeta]-potential was measured on a Zeta Sizer Nano ZS90 (Malvern Instrument, Worcs, UK) by using laser doppler microelectrophoresis. In this technique, an electric field was applied to the micelles, which then moved with a velocity related to their [zeta]-potential.
After standing for 3 days, the zeta potential was measured using JS94G+ microelectrophoresis apparatus (Shanghai Zhongchen Digital Technique Equipment Ltd Co., Shanghai, China) and the values of zeta potential were calculated using a computer with specific software (Hou et al.
