analysis | a highly sensitive microbial biosensor is constructed using the recombinant Escherichia coli BL21-C23O cell as bio-recognition element for catechol detection. Based on the synergistic effect of catechol 2,3-dioxygenase and nanoporous gold, the resulting microbial biosensor exhibits good performance for catechol detection with high sensitivity, strong anti-interference and good stability | Sphingobium yanoikuyae |
