pDawn-LKD-T1

Description

This composite part is a generator consisting of pDawn (cI-LVA) (BBa_K1075044) and LKD (BBa_K4325004).

Usage

The pDawn (cI-LVA) blue light corresponding system (BBa_K1075044) and the lysis gene LKD (BBa_K4325004) were inserted into the pSEVA331 expression vector, which was inserted into E. coli TOP10 and screened out bacterial colony that grew in the dark but did not grow under blue light. Finally, the pSEVA331-pDawn (cI-LVA) -LKD-T1 plasmid was extracted and inserted into G. hansenii ATCC53582, after which we verified the responsiveness of pDawn (cI-LVA) to blue light.

Characterization

1.Batch screening of pDawn(cI-LVA)-LKD-T1-pSEVA331 in response to blue light lysis in E. coli TOP10.

As shown in Figure 2, except for the 16th bacterial colony,almost all of the plaque did not grow under blue light. To further show the lysis effect of pDawn (cI-LVA) -LKD-T1-pSEVA331-TOP10, we measured the OD 600 values of pSEVA331-pDawn (cI-LVA) -LKD-T1-TOP10 periodically and ploting the growth curve diagram . As shown in Figure 3, pSEVA331-pDawn (cI-LVA) -LKD-T1-TOP10 was not excellent.
