As for the anode, the biopolymers were degraded into small molecules due to electrochemical

oxidation, which greatly reduced the impact of DOM on dewatering effect. Therefore, the opera
ting conditions (voltage, pH and ionic strength) caused changes in electrochemical effects, which

played a crucial role in compartmentalization of sludge
EPS dissolution and consequently sludge electro-dewatering behavior. (C) 2017 Elsevier

摘 要 ：Heavy metal contamination is a global environmental issue as it poses a
significant threat to public health, and exposure to metals above a certain threshold level can
cause deleterious effects in all living organisms including microbes. To survive in such harsh

environments, some microbes evolved a few defence mechanisms to metabolize and transform
heavy metal into a less hazardous form,

resulting in the formation of heavy-metal-
resistant microbes. Heavy-metal-resistant

microbes can be used in bioremediation
to remediate the contaminated areas.

Bioremediation uses natural biological
activities, is relatively low-cost, and has high

public acceptance. Herein, we summarize
the interactions and mechanisms that occur

between the microbes and heavy metal, including stress responses and defence mechanisms,
which involve aggregation and biofilm formation, production of extracellular polymeric

substances (EPS), and development of resistance genes and signalling pathways against heavy
metals.
