Περίληψη
The attachment of Pseudomonas (P.) putida onto well (KGa-1) and poorly (KGa-2) crystallized kaolinitewas
investigated in this study. Batch experiments were carried out to determine the attachment isotherms of
P. putida onto both types of kaolinite particles. The attachment process of P. putida onto KGa-1 and KGa-2
wasadequately described by a Langmuir isotherm. Attenuated Total Reflection Fourier Transform Infrared
Spectroscopy 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 than
KGa-1. It was shown that electrostatic interactions and clay mineral structural disorders can influence
the attachment capacity of clay mineral particles.
