The adsorption of modified polyacrylamide polye!ectrolytes and their efiect on the flocculation of negatnrly charged polystyr:ne latex were investigated. Conditions were chosen so mat the adsorbed poly;ncrs approached cquilibrlum configuration before the occurrence of appv-iable flocculation. Polyme
Flocculation of micro-organisms in their complex media is shown to be difficult. The natural cationic flocculant chitosan can successfully flocculate yeast from a complex broth. The difficulty caused by complex media is believed due to the flocculant preferentially complexing with anionic polymers i
The strength of floes formed by the chitosan induced flocculation of yeast depends on the nature of the suspending medium. The addition of anionic polymers to the medium prior to flocculation by the cationic polyelectrolyte chitosan can increase the resilience of the floes.
