Electric field light scattering as a means of studying the effects of additives on bacteria

摘要: Abstract Bacteria in suspension may be oriented by the action of applied electric fields owing to presence dipole moments that are associated with bacteria. For polydisperse suspensions nonspherical bacteria, these changes followed observing accompanying either turbidity, or intensity light scattered from suspension. From such observations size and direction apparent permanent induced can evaluated. The moment has been found extremely sensitive small amounts additives, whether they polar, ionic, surface active, nonsurface active additives. Illustrative data presented for effect alcohols, antibiotics, urea, formaldehyde, cetyltrimethylammonium bromide, sucrose, on organism Escherichia coli. possibility using electrical parameters study interactions is considered.
