摘要：

Heavy metal-resistant bacteria secrete extracellular proteins (e-PNs). However, the role of e-PNs in heavy metal resistance remains elusive. Here Fourier Transform Infrared Spectroscopy implied that N-H, C=O and NH(2)-R played a crucial role in the adsorption and resistance of Ni(2+) in the model organism Cuprividus pauculus 1490 (C. pauculus). Proteinase K treatment reduced Ni(2+) resistance of C. pauculus underlining the essential role of e-PNs. Further three-dimension excitation-emission matrix fluorescence spectroscopy analysis demonstrated that tryptophan proteins as part of the e-PNs inc...
