Abstract
This study shows the experimental results of the rare earth element and Y (REY) distribution patterns between heterotrophic bacteria and water under acidic pH conditions for five different bacterial strains (Microbacterium sp., Curtobacterium sp., Bacillus subtilis, Pseudomonas putida, Bacillus pumilis) which are widespread in natural and technogenic ground- and surface waters of the Far East of the Russian Federation. The insignificant distribution pattern between heavy and light REE, a negative Ce and Dy anomalies and a positive Eu anomaly were found. It was discovered the selectivity of the REY biosorption by the Gram-positive and Gram-negative bacteria and the time response of the biosorption process in a more acid environment.
