I'm using Sporosarcina pasteurii to remove heavy metals from wastewater by producing metal carbonates. The issue I encounter is that high metal concentrations (i.e. Co 2g/L) strongly inhibit bacterial growth and activity.

One of the existing solutions is to isolate another already metal-tolerant strain (such as Lysinibacillus sphaericus). (source :

I have read that it is possible to adapt a bacterial culture to a high concentration of metals by serial acclimatisation, where the bacteria are successively grown in a medium of increasing metal concentration. (source : 10.1016/j.wasman.2018.07.010)

Can this method be adapted to ureolytic bacteria? Are there any examples?

If not, what other methods would you suggest?

Thank you !!
