P & P
Projects first and foremost must be important to people. We answer why our project is important and what we have done to involve communities.
DRYLAB
A dry lab is a laboratory where computational or applied mathematical analyses are done on a computer-generated model to simulate a phenomenon in the physical realm.
WETLAB
A wet lab is a type of laboratory in which a wide range of experiments are performed, for example, characterizing of enzymes in biology, titration in chemistry, diffraction of light in physics, etc. - all of which may sometimes involve dealing with hazardous substances.
ABOUT US
Our project focuses on demonstrating flotation of Escherichia coli using gas vesicle proteins (GvPs) as a novel cellular separation technique for bioremediation processes. Previous iGEM teams have demonstrated gas vesicle production and flotation in mammalian and yeast cells using GvPs from various bacterial species. Shapiro et al., (2018) engineered a GvP-producing plasmid using arg1 from Aphanizomenon flos-aquae and Bacillus megaterium to synthesize these echogenic structures and observed that high expression enabled E. coli to float. Our goal is to replicate and improve their flotation results by modifying arg1 to achieve consistent flotation using a specific induction protocol. We propose that using this technique may be a cost-effective separation technique for various bioremediation processes. Upon sorption or uptake of pollutants or valuable materials, this technique could allow for simpler extraction of pollutant-harboring or heavy metal-bound bacteria. We have developed a bioreactor model to investigate this claim.
