Process for the separation of heavy metals, use of the process and use of a system for the purification of heavy metals contaminated waters or for the detection of heavy metals in waters

摘要

Process for the separation of heavy metals, comprising the following steps: a. Contacting a solution containing a minimal medium and metabolically active biomass from Gram-negative bacteria with a solution containing heavy metals, wherein metabolically active bacterial biomass from bacteria of the strain Pseudomonas fluorescens CCUG 32456 A is used, b. Adjusting the phosphate concentration to 0.2 mmol / l to 0.5 mmol / l after contacting the solution, whereby a molar ratio of phosphate: heavy metals of at least 1:10 is reached, wherein phosphate induces the formation of a precipitating heavy metal cell agglomerate.
