Burkholderia Fungorum, A promoter biological tool for heavy metals bioresorption

Abstract

In this work, we studied the effect of Burkholderia fungorum strain Bf01 bacterium on three heavy metals bioresorption: cadmium, copper and zinc. The heavy metals bacterium resistance was studied in liquid minimum standard medium, added with increasing metals concentrations. Furthermore, the Burkholderia fungorum strain Bf01 was monitored during its growth for its capacity to reduce high metals. The strain Bf01 showed high Minimal Inhibitory Concentrations about (1500 mg/L, 400 mg/L and 50 mg/L) for Cadmium, Zinc and Copper, respectively. Therefore, it was assumed that Burkholderia fungorum strain Bf01 had a high metals resistance degree especially for cadmium and it exhibited a high adsorption affinity and removal metals from bacterial suspensions. As a result, Burkholderia fungorum strain Bf01 presents an excellent biological tool for heavy metals bioresorption for its efficiency, reliability and low cost.
