DISColi:Bio-photolithography in Device Engineering Using Different Wavelengths of Light
The DISColi project aims to design and construct a novel bio-photolithographic system for the engineering of biofilms into functional 2D and 3D structures and devices in response to different patterns and wavelengths of light
In this project we worked with light responsive promoters, a novel biofilm-forming synthetic biology chassis, E. coli Nissle 1917, and novel biobricks including several designed for biofilm dispersal and fluorescent reporters with wider utility than GFP.
The main aims of our project can be separated into three light-controlled components: the designed sculpting of biofilms; 3D printing for encapsulation of cells; and the controlled modular synthesis of a variety of products.
Applications
Build your own nano-biofactory - Use the DISColi system to form a biofilm then use different colours of light to select from a range cellular products from a single strain. Having the products only in the biofilm cells allows for easy purification of the products in the amount you require. Personalised nutritional supplements and and pharmaceuticals - In remote locations which are difficult/costly DISColi system can be used. This means that from a single culture can selectively product a range of useful compounds from a common precursor, such as opioids and isopenoids, tailored to exactly what is needed. Microfluidics - Grow a microfluidics platform using biofilm to form the channels. These channels can be dispersed resetting the system and allowing the formation of new channels. Tissue Engineering - Use precises laser light to form tiny 3D structures out of biofilm that can be used as a scaffold for tissue culture. Light Controlled Multicellularity - Use different colours of light to control dispersal of different strains of microbes allowing the precise construction of a mixed community biofilm. Clean Bioreactors - Biofilms are costly to clean from pipes and bioreactors. Using the DISColi system of light based dispersal of biofilms can stop the build up and even break down excisting biofilms in pipes and bioreactors. Simply shine light of the right colour to trigger the dispersal mechanism will start production surfactant proteins that have been shown to disperse biofilm.
Highlights!
In the course of our project we have created many noteworthy biobricks and have made a series of very interesting discoveries. Here are our personal highlights, including our favourite biobricks, our new chassis, and our public presence. Have a look!
Judging Criteria
In this section we explain why we deserve a gold medal in accordance with the iGEM judging criteria. If you have very little time, this may be exactly what you are looking for!
E.coli Nissle 1917
Our new transformable, non-pathogenic, biofilm-forming chassis!LOV2 and iLOV Reporters
LOV2 and iLOV are our incredible new reporters. Not only are they smaller, florescene brighter and recover from photobleaching faster than GFP but it also functions in anaerobic conditions! Try tagging your favorite proteins.c-di-GMP Phosphodiesterase
c-di-GMP Phosphodiesterase breaks down c-di-GMP, which is a secondary messenger which regulates many behaviours such as motility and biofilm formation. Over-expressing this phosphodiesterase should decrease the levels of c-di-GMP, increasing cellular motility and causing biofilm dispersal. c-di-GMP has many more functions making this biobrick useful in a wide range of applications.Ranaspumin2

Multiple Cloning Site Biobrick
We were slowed down due to repeated rounds of restrictions and ligations to put multiple different coding regions with the same promoter, RBS and terminator combo. So we designed this handy multiple cloning site biobrick to speed up that process.Sponsors
With many thanks to our generous sponsors, without whom this project would not have been possible.
