Biosorption of direct scarlet dye on magnetically modified Saccharomyces cerevisiae cells
|
Abstract:
We prepared the nano-sized magnetic fluid in aqueous phase solution to modify the killed yeast cells (Saccharomyces cerevisiae). Subsequently, the yeast cells with good magnetic response was obtained.The infrared spectroscopy analysis showed that the modified yeast cells increased obviously the absorption at the Fe-O characteristic peak of 581 cm?1. Moreover, the transmission electron microscopy picture indicated the magnetic nanoparticles presented individually or aggregately on the yeast cell surface. Und...
