TL;DR
This study investigates how two Arthrobacter bacterial species absorb silver ions (Ag I), determining their biosorption constants through dialysis and atomic absorption analysis to understand their interaction mechanisms.
Contribution
It provides the first comparative analysis of Ag I biosorption constants for Arthrobacter globiformis and Arthrobacter oxidas, revealing differences in their biosorption capacities.
Findings
Biosorption constants are 65.0 x10^-4 for Arthrobacter globiformis.
Biosorption constants are 35.0 x10^-4 for Arthrobacter oxidas.
The study characterizes the interaction nature between Ag I and bacterial species.
Abstract
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.
