Question

Microbes that exhibit a low tolerance or have become adapted to low concentrations of soluble heavy metals in the leach suspension should be selected for bioleaching.

(a) True

(b) False

I got this question in class test.

My doubt stems from Microbes in Bioleaching Process topic in portion Bioleaching and Biomining for Recovery of Resources of Environmental Biotechnology

Answer 1

The correct answer is (b) False

The explanation: Microbes that exhibit a high tolerance or have become adapted to high concentrations of soluble heavy metals in the leach suspension should be selected for bioleaching. This is because microbes of different genus or different strains of same species show different sensitivities to different heavy metals.
