Summary
The immobilization intensity of cells of Penicillium frequentans and Candida parapsilosis on materials such as granular clay, granular clay + aquifer sand and aquifer sand alone, was followed by scanning electron microscopy (SEM). The results demonstrate that the granular clay was the best adsorbent for both organisms, followed by the mixture of both granular clay and aquifer sand. Poor adhesion of cells was detected on using aquifer sand alone with C. parapsilosis.
The highest degree of degradation of the alkane mixture (C12−C18) used was achieved by cells immobilized on granular clay, followed by those cells adsorbed on clay and sand. The weakest degradation was observed with cells immobilized on the sand alone.
