The pH response over time was again measured but this time, we used liquid cultures which were already saturated (i.e. in the stationary phase).  The results will be put up soon.

Today we tested the timed pH response in 2 cell cultures:  1 with the LacZ gene, which was activated by IPTG, and one that had this gene absent.

The colonies transformed on the 6th made it this time, and we isolated the plasmid DNA from three individual colonies for each biobrick. We also transformed some E. coli with

When bacteria with the lacZ gene inserted are present in a medium containing lactose, the pH does drop significantly.

Unfortunately the colonies we plated on the 4th did not survive due to a problem with the competent cells we used, so today we repeated transforming and plating colonies containing the following parts:
