| Abstract: | In this study, Arthrobacter luteolus, isolated from rare earth environment of Chavara (Quilon district, Kerala, India), were found to produce catechol-type siderophores.
The bacterial strain accumulated rare earth elements such as samarium and scandium. The siderophores may play a role in the
accumulation of rare earth elements. Catecholate siderophore and low-molecular-weight organic acids were found to be present
in experiments with Arthrobacter luteolus. The influence of siderophore on the accumulation of rare earth elements by bacteria has been extensively discussed. |
