A novel bio-sorbent comprising encapsulated Agrobacterium fabrum (SLAJ731) and iron oxide nanoparticles for removal of crude oil co-contaminant, lead Pb(II)

A novel adsorbent, iron oxide nanoparticles and A. fabrum strains encapsulated in calcium alginate, was prepared for the removal of lead. The crude oil degrading strain was isolated from core samples from Assam Oilfield, India and was able to resist lead up to 2900 mg L−1 thus proving to be a highly lead tolerant. Chemically synthesized Fe3O4 magnetic nanoparticles (10–20 nm) by co-precipitation method were characterized using various...
