Response of indigenous Cd-tolerant electrochemically active bacteria in MECs toward exotic Cr(VI) basedon the sensing of fluorescence probes

Xia Hou, Liping Huang, Peng Zhou, Hua Xue, Ning Li

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 4, doi: 10.1007/s11783-018-1057-4

Abstract:

Cell membrane of indigenous Cd-tolerant EAB harbored more cadmium than chromium.

Indigenous Cd-tolerant EAB cytoplasm located more chromium than cadmium.

Simultaneously quantitatively imaging Cd(II) and Cr(III) ions in EAB was achieved.

Current accelerated the harboring of cadmium in EAB at an initial 2 h.

Current directed the accumulation of more chromium in EAB over time.
