+ | Every year, one third of global food production -1.3 billion tons of food- is thrown away, partially due to the “best before” dating system. | ||
+ | <z7>iGEM Groningen 2012</z7> seeks to provide an alternative method of assessing edibility: the <z7>Food Warden</z7>. It uses an <z7>engineered strain</z7> | ||
+ | of <i>Bacillus subtilis</i> to detect and report volatiles in spoiling meat. The introduced <z7>genetic construct</z7> uses a promoter to trigger | ||
+ | a pigment coding gene. This promoter, <z7>identified by microarray analysis</z7>, is significantly upregulated in the presence of | ||
+ | <z7>volatiles from spoiling meat</z7>. The activity of the <z7>promoter</z7> regulates the expression of the <z7>pigment reporter</z7> and will | ||
+ | be visible to the naked eye. For safe usage of the system, spores of our engineered strain are placed into one half of a semi-permeable | ||
+ | <z7>capsule</z7>, the second containing a calibrated amount of nutrients. Breaking the barrier between the two compartments allows | ||
+ | <z7>germination and growth</z7>, thereby activating the <z7>spoiling-meat sensor</z7>. | ||

2.We explored the definition of spoiled meat and ways to check meat spoilage. We identified various compounds present in spoiled meat. |
3. We identified spoiled meat sensors by transcriptome analysis. |
4. Backbone Psac-cm: easy cloning in B. subtilis, the BioBrick way, for the first time! It's easy to check, biobrick compatible, E. coli compatible, stabily inserted into the B. subtilis chromosome |
|
6. Most importantly: we developed a construct which makes Bacillus subtilis sense spoiled meat and produce an output in the form of a yellow or purple pigment visible by naked eye. |
