GMU:Synthetic Biology/Product Screening

2009 Wiki - possible products

Aberdeen_Scotland

"Pico Plumber", a strand of bacteria that can find leaks and corrosion in pipes, reaching them by chemotaxis (although how this would work in real-life is not clear from their wiki, since the bacteria need an attractant. would need to be some kind of chemical that is released from pipes when they break). Upon reaching high density at the leaking site, they start producing a glue enzyme (not really specified, they mention tropoelastin, a protein that makes blood vessels elastic. can't tell from their wiki if that's their "glue"). Can be something you can use on a small scale at home for your water pipes.

British Columbia

E.coli Traffic Light

A strand of E.coli bacteria that senses chemicals of choices and gives a green, yellow or red fluorescent output. Could show a potentially dangerous rise in concentration for pollutants. Same as Cambridge, but with fluorescent proteins, which is very unhandy for at home use.

Brown

Allergene

A naturally occurring bacterium in the human nasal flora, Staphylococcus epidermidis, is used as a vehicle for the delivery of an anti-allergic drug that is produced only upon allergic reaction. This would come in the form of a nasal spray, I assume.

Cambridge

E. chromi

The E. Chromi strain of bacteria can be used for out- and indoor sensing of chemicals (i.e. pollutants) and gives a colour output in form of visible dye that can be directly analysed without fancy laser equipment. Plus the sensor is concentration sensitive.

Chiba

E. coli timer

A timer that is triggered by a chemical and depending on concentration gives an output after a certain time. Could be used together with E. chromi, or for boiling eggs.

Cornell

again a biosensor in form of a bacteria. It can sense the toxic heavy metal cadmium (very important for agriculture). Output is a fluorescent protein.

UAB-Barcelona and uChicago

A bio senser for the recognition and removal of water pollutants (Trihalomethanes, Nitrite, Nitrate and orthophosphate ions), i.e. chloroform. The bio sensor runs in E. coli or yeast and has (for detection purposes) a GFP fluorescent protein as output. This product could be used in order to perform an easy water-quality test at home and thereby to minimize health-risks.

UCSF

They planned to program mammalian cells to perform a certain movement according to chemical gradients. They call it nano-bot in robot analogy. As future product possibilities they state: "Imagine, for example, therapeutic nano robots that could home to a directed site in the body and execute complex, user-defined functions (e.g., kill tumors, deliver drugs, guide stem cell migration and differentiation)."

UC Davis

This team envisions a medical product for curing Celiac Disease. Celiac Disease is the disease where people are unable to digest gliadin, a protein present in gluten. So they have to stick to a strong gluten-free diet. The team wants to engineer a micro-organism able to produce the enzyme for digesting gliadin. Therefore they work on

1. an enzyme secretion part
2. a pH detection part in order to limit the production of the enzyme to the stomach, where the digestion should be performed

ULB-Brussels

Development of a synbio-Glue produced by an engineered E. coli strain. This project takes advantage of a natural, bacterial glu, that has the following properties:

1. three times stronger than actual glues
2. glue that is able to strongly bind a wet surface

UNIPV-Pavia

Production of Ethanol from waste, i.e. toxic left over during cheese production. In general the approach to produce energy (i.e. ethanol) from energy-rich waste (i.e. plants, natural products) is one big goal of synthetic biology and would have a huge impact on energy production and the energy market.

UNIPV-Pavia

Beating obesity by approaching the topic as follows: Our goal is to engineer a strain of Lactobacillus to express the enzymes required for the synthesis of cellulose (a bio-polymer which is non-toxic and non-digestible for humans) from glucose (sugar) in an attempt to reduce the caloric intake of obese individuals.

Uppsala-Sweden

Biofuel (ethanol, butanol) production from sun light. Approach: using cyanobacteria (being able to use light as energy source) for the production of those biofuels.

Valencia

Lightnig Cell Display: Building of a bio-screen consisting of yeast being able to sense electric stimuli and produce light. Although such a display seems to have no advantage over normal, classic display, it has indeed some interesting properties:

1. dot-size is equal to the size of single cells (super-high resolution)
2. no electricity needed for color production --> energy saving
3. cells have interesting properties (can move etc.), which may lead to new possibilities in computer-screen engineering

please address questions according to those projects to Dominik
