Bioavailability of Ag(I) with Arthrobacter oxidas and Arthrobacter globiformis

The biosorption of Ag(I)_ Arthrobacter species (Arthrobacter globiformis 151B and Arthrobacter oxidas 61B) was studied at simultaneous application of dialysis and atomic absorption analysis. The biosorption constants and nature of interaction for Ag(I) -Arthrobacter oxidas and Ag(I) -Arthrobacter globiformis were determined. The biosorption constants for Ag(I)- -Arthrobacter globiformis and for Ag(I) -Arthrobacter oxidas equal to 65.0 x10-4 and 35.0 x10-4 respectively.
