Περίληψη

The attachment of Pseudomonas (P.) putida onto well (KGa-1) and poorly (KGa-2) crystallized kaolinitewasinvestigated in this study. Batch experiments were carried out to determine the attachment isotherms ofP. putida onto both types of kaolinite particles. The attachment process of P. putida onto KGa-1 and KGa-2wasadequately described by a Langmuir isotherm. Attenuated Total Reflection Fourier Transform InfraredSpectroscopy and Nuclear Magnetic Resonance were employed to study the attachment mechanisms of P.putida. Experimental results indicated that KGa-2 presented higher affinity and attachment capacity thanKGa-1. It was shown that electrostatic interactions and clay mineral structural disorders can influencethe attachment capacity of clay mineral particles.
