Light scattering by bacteria

摘要: Abstract E. coli is a short rod-like bacterium which, in aqueous suspension, scatters visible light such way that peaks are encountered the angular scattering diagram. With polydisperse sample this fine structure lost. Because of this, it has been possible to make meaningful interpretation measurements changes scattered when suspensions were subjected either pulsed or continuous direct current and alternating electric fields. Apart from indicating particle size, electrical properties bacteria revealed. The characterized by predominant permanent dipole moments across induced dipoles along their major axis. seem be better accounted for terms Maxwell-Wagner type surface polarization rather than bulk process. These compared with results other workers.
