文摘
- •
We characterized arsenic resistant Rhizobium in a metal contaminated soil.
- •
Cell morphology, protein expression and EPS production was examined in Rhizobium.
- •
FTIR and SEM-EDS analyses demonstrated arsenic-EPS interactions.
- •
Arsenate uptake (biosorption) by in EPS was significantly higher compared to whole cell.
- •
The results contribute to better understanding of cellular and metabolic changes in Rhizobium.
