The kinetics of biocide uptake in a model biofilm

摘要: Abstract A theoretical analysis of the uptake biocides by biofilms is presented, together with results experiments on copper a model biofilm composed agar-agar. The show that partition coefficient between and water varies concentration rate not proportional to its concentration. In 10 mM aqueous sulphate agar biphasic. indicate three separate processes are involved in agar: solution intersitial gel, ionic binding chelation. from determines length time necessary achieve biocidal concentrations within biofilm. Further systematic studies kinetics needed select those which best suited for elimination sessile organisms.
