“…However, when the concentrations of metal ions are high, they become cytotoxic. The current research in the literature on the direct toxicity of metal ions to APM mainly focuses on Ag + , Li + , Co 2+ , Ni 2+ , Hg 2+ , Bi 3+ , and Cu 2+ (Huang et al 2020 ; Liu et al 2020a , b ; Wu et al 2018 ).…”

In modern societies, the accumulation of vast amounts of waste Li-ion batteries (WLIBs) is a grave concern. Bioleaching has great potential for the economic recovery of valuable metals from various electronic wastes. It has been successfully applied in mining on commercial scales. Bioleaching of WLIBs can not only recover valuable metals but also prevent environmental pollution. Many acidophilic microorganisms (APM) have been used in bioleaching of natural ores and urban mines. However, the activities of the growth and metabolism of APM are seriously inhibited by the high concentrations of heavy metal ions released by the bio-solubilization process, which slows down bioleaching over time. Only when the response mechanism of APM to harsh conditions is well understood, effective strategies to address this critical operational hurdle can be obtained. In this review, a multi-scale approach is used to summarize studies on the characteristics of bioleaching processes under metal ion stress. The response mechanisms of bacteria, including the mRNA expression levels of intracellular genes related to heavy metal ion resistance, are also reviewed. Alleviation of metal ion stress via addition of chemicals, such as spermine and glutathione is discussed. Monitoring using electrochemical characteristics of APM biofilms under metal ion stress is explored. In conclusion, effective engineering strategies can be proposed based on a deep understanding of the response mechanisms of APM to metal ion stress, which have been used to improve bioleaching efficiency effectively in lab tests. It is very important to engineer new bioleaching strains with high resistance to metal ions using gene editing and synthetic biotechnology in the near future.

“…For example, EPS produced by Sulfobacillus thermosulfidooxidans have strong adsorption properties for copper, nickel, zinc, and cadmium. The deprotonation of carboxyl and phosphoryl groups in EPS also contributes to the adsorption of heavy metal ions (Huang et al 2020 ).…”
