Title: Synthesis of hyper-flagellated phototaxic ''E. coli''.
 +
 +
Purpose: To create a bacteria that can induce a micro-flow regulated by light.
 +
 +
Host: Bacteria, ''E. coli''.
 +
 +
Strains: Mg1655 and TOP10.
 +
 +
Donor:
 +
Coding regions amplified from naturally occurent organism.
 +
Photosensor: ''N. Pharaonis'', ''S. Enterica serovar typhimurium''. These create a fusion protein. Sr2 + Htr2 fra N. P. tar CheW from S. E.
 +
Retinal: ''D. Melanogaster'' fra cDNA gen ninaB?
 +
Flagella: ''E. Coli'': gen flhDC
 +
 +
Vektors:
 +
pSB3TS
 +
pSB3CS
 +

Risk-assessment
 +
 +
Host:
 +
Bacteria:
 +
''E. coli'' is naturally occurring and the strains used for amplifying vector-DNA/proteins is not reported pathogenic
 +
Al material used in bacterial work is autoclaved and/or Inactivated with Iodofor
 +
 +
Stains:
 +
A cell-culture from a higher eucaryot which does not contain any endogene vectors that would be able to mobilize parts of the transferred genetic material
 +
The strains used have not been reported pathogenic
 +
The cellular strain is very fragile and is unable to procreate or survive outside of laboratory conditions, as they need the correct temperature, humidity, pH, CO2, O2 and nourishment
 +
Al material used in bacterial work is autoclaved and/or inactivated with iodofor
 +
 +
Donor:
 +
Naturally occurring healthy genes of insect origin and it is not believed to be able to transform/infect human cells in vitro/vivo. The risk is therefore considered to be minimal. The S.E. gene has homology in E. coli and is therefore not considered to pose any threat.
 +
Vector:
 +
Vectors are of pUC or pOt2 origin and nothing from the vector has human recombinations/infection potential and the risk of working with these strains are therefore believed to be minimal.
 +
Our vector is in addition equipped with resistance to antibiotics and cannot exist without it. Should discard the resistance if not within a antibiotic environment.
 +
 +
Insert:.
 +
Is naturally occurring genes with well-defined tags and it is believed that they cannot transform/infect human cells in vitro/vivo. The fusion-protein has had limited testing, but is also considered safe. The risk is therefore believed to be minimal.
 +
 +
Health-aspects of the final GMO:
 +
Bacteria not exposed to antibiotics will discard the plasmids within a very short timespan.
 +
The bacteria are modified with plasmids, and will return to a non-GMO state within a short time-span. The modification is not infective/self-reproductive in humans. It is not believed to pose any threat towards human health.
 +
We have at no point worked with any self-reproductive or pathogenic material
 +
 +
Assessment: Class 1
