biostudies-literatureUnknown35Disi ZACrude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and bio-accumulation. Biomineralization, performed through many microbial processes, can lead to the immobilization of heavy metals in formed minerals. The potential of the microbially carbonate-induced precipitation (MICP) in removal by biomineralization of several heavy metals was investigated. A collection of diverse 11 bacterial strains exhibited ureolytic activity and tolerance to heavy metals when growing in Luria-Bertani (LB) and urea medium. Determination of the minimum inhibitory concentrations (MIC) revealed that heavy metal toxicity was arranged as Cd > Ni > Cr > Cu > Zn.Biotechnology reports (Amsterdam, Netherlands)e00747https://www.ebi.ac.uk/biostudies/studies/S-EPMC9218142biostudies-literatureImmobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria.PMC9218142Disi ZAAttia EZouari NAhmad MIfalseImmobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria.Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals.
