The experimental study of methylene blue and crystal violet adsorption by dead microorganisms (Saccharomyces cerevisiae, Sarcina lutea, Serratia marcescens and Bacillus subtilis) leads to the conclusion that unimolecular or multimolecular layers of dyes can be formed, depending on the relative values of the cell and dye concentrations.Obviously, the adsorption method for specific cell area measurement proposed by Borzani^<9〜10)> can be applied only when unimolecular layers are formed.When the experimental conditions lead to multimolecular layer adsorption, the applicability of the physico-chemical laws of Freundlich and Lagmuir is only formal.In such cases, the results obtained until now do not make if passible to test the applicability of other adsorption laws.
