A strain of E.coli
commonly used in lab
work to amplify some protein
you want produced in large ammounts. The construction of this strain is rather clever since it apart from the protein you make it produce also expresses a lysozyme
which after freeze-thawing the bacteria results in their lysis
Yes, this is intelligent but I still feel as if were exploiting the poor coli, cheating it into producing a substance which ultimately will lead to its own destruction. Lets just say I´m glad I don´t have to experiment on animals.
