Adaptive laboratory evolution of cadmium tolerance in Synechocystis sp. PCC 6803.

ABSTRACT:

Background

Cadmium has been a significant threat to environment and human health due to its high toxicity and wide application in fossil-fuel burning and battery industry. Cyanobacteria are one of the most dominant prokaryotes, and the previous studies suggested that they could be valuable in removing Cd²⁺ from waste water. However, currently, the tolerance to cadmium is very low in cyanobacteria. To further engineer cyanobacteria for the environmental application, it is thus necessary to determine the mechanism that they respond to high concentration of cadmium.

Results

In this study, a robust strain of Synechocystis PCC 6803 (named ALE-9.0) tolerant to CdSO₄ with a concentration up to 9.0 µM was successfully isolated via adaptive laboratory evo
