We transferred the plasmid pBAD-MazF into E.coli DH5α. The bacteria in the experimental group were cultured in the liquid LB-ampicillin medium supplemented with L-arabinose. The concentration of L-arabinose is 1.5μM/L. The bacteria liquid was then diluted and spread on solid medium. 24 hours later, no obvious colony was observed in the group with L-arabinose, but the bacteria in the blank control group grew normally. It is proved that the growth of bacteria is inhibited in the case of MazF expression.

E.coli BAD +MazF

This is a suicide switch controlled by an arabinose operon. When arabinose is present, the bacteria activate the suicide switch and die.

Characterization

We transferred the plasmid pBAD-MazF into E.coli DH5α. The bacteria in the experimental group were cultured in the liquid LB-ampicillin medium supplemented with L-arabinose. The concentration of L-arabinose is 1.5μM/L. The bacteria liquid was then diluted and spread on solid medium. 24 hours later, no obvious colony was observed in the group with L-arabinose, but the bacteria in the blank control group grew normally. It is proved that the growth of bacteria is inhibited in the case of MazF expression.
