| − | The project involves the manipulation of non-pathogenic <em>E.coli </em> (E.coli DH5 alpha and <em>E.coli </em> BL21DE3) so it is currently being developed in safety level 1 molecular biology laboratory. In order to fulfill biosafety rules, we wear lab coats, rubber gloves and sometines cotton masks. All biologial waste has to be treated with chlorine and there is a special section for liquid waste treatment. In molecular Biology organic acids, alkaline solutions and other corrosive reagents will be carefully monitorized and only authorized personal manipulate it. It is imperative that all the members of the group read the disposal protocols for every kind of solid and liquid waste. We have protocols of use of acids, alkaline solutions, liquid nitrogen and sterilization of biological material. It is of course forbidden to eat or drink in the laboratory.</p> | + | <p>The project involves the manipulation of non-pathogenic <em>E.coli </em> (<em>E.coli </em> DH5 alpha and <em>E.coli </em> BL21DE3) so it is currently being developed in safety level 1 in the molecular biology laboratory.

This system is arabinose-dependent: the culture medium contains arabinose, which inhibits the apoptosis process. If bacteria escape, the lack of arabinose will trigger the death cell mechanism.</p> |
