Application

Application Comment Organism
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

catechol + O2 compared to the enzyme from Sphingobium yanoikuyae XLDN2-5, the recombinant Escherichia coli BL21 overexpressed C23O exhibits higher catalytic activity towards catechol. The whole cells provided a better environment for C23O to maintain its catalytic activity and stability compared with crude enzyme Sphingobium yanoikuyae 2-hydroxymuconate-6-semialdehyde
