<p>Since we propose using B. subtilis as a chassis for our waste water treatment bacteria, we first set about determining the concentration of different metal ions that the non genetically altered chassis can cope with. We initially observed cell density of cultures after 8 hours incubation with varying metal concentrations. Following this we recorded culture density every hour to obtain growth data for appropriate concentrations of metals, as indicated by the initial 8 hour cultures. These experiments continue...

[edit] Chronological notebook

  • 27th of June:

Fluorescence We did blabla, no fluorescence.

  • 1st of July:

Headline EtOH resistance assay was continued in a narrow concentration range (Jan).

E. coli (DH5alpha) cells were transformed using BioBricks required for EtOH production (Aleksandra).

O/N cultures of E. coli and B. subtilis were set up to continue with the experiments tomorrow (Harry).
