Project Ideas
This is a list of the ideas that have been covered during the course of the first iGem meetings. Included within some of the paragraphs are links to articles which gave inspiration for that particular idea
Ideas discussed for iGEM
MAN-SCAN
Last year the Newcastle team used bacteria to detect bacteria. How about using a similar approach to detect humans? Maybe we can come up with a less androgynous title. I visualised a lawn of B. subtilis onto which you place a body part (eg hand or foot) and later an image of it appears in light.
SYNCHRO-BAC
One large colony is glowing in the dark and send a message to other colonies to do the same.
HAPPY-BACTY - general environmental monitor.
B. subtilis seems to be quite good at detecting and responding to environmental stresses (is there a thing called a stressosome?). We could ask simple questions of the colonies - is your environemnt Nice, average or poor? maybe get a three colour output (traffice lites). This kind of thing is an environmentalist dream - to detect an average of environmental stressors in theis way, such as pollutants maybe the environmental monitor uses synchro-bac to tell the others what they are "feeling" and if they were motile the other could move to a nice area, or away from a bad one.
Trapping of heavy metals then sporolate to fix them indefinatley
Metal Resistance in Acidocella Strains and Plasmid-Mediated Transfer of This Characteristic to Acidiphilium multivorum and Escherichia coli
Biological memory
Bacillus subtilis is a sporulating bacteria and can survive for years in its spore form. Also, we can make them respond to external stress such as electro-magnetic fields. Use these two features to engineer bacterias capable of storing information for years. This could become an immortal and unlimited memory. We could use bacterias in some way so that bacteria are 0 or 1 and use this to make a bacterial hardware or memory that is capable of storing octets and therefore that has memory.
Allergen detection and removal
Using bacteria as quality control and disabling of allergens by detection of peptides found to elicit allergic response in food, such as nut, shell fish, egg, dairy traces etc. Samples from batches could in theory be tested with a fluorescent output.
Calculator : Implementation of a simple calculator to add numbers
Soil Enhancer
Detection of nutritions on the soil and freeing up the minerals for the plants ([http://www.bcmicrobials.com/products_biostart.php?PHPSESSID=6e2f9df3e98e0bec71c2aa406a9f0ef0 Article]) - maybe detect the N, P, K elements in soil and give different feedback like colour or flourescence , adjust it's metabolism system to generate a product which can be absorbed by plants easily.
Fast bacteria
Engineering the movement of bacteria with feedback systems like rockets ([http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=193742 Article])
Inflammatory disease treatment
This idea is a little similar to the allergen detector and corrector system - it involves using Bacillus subtilis in humans to target and deal with a particular allergen particle before the immune system sets in and creates the damaging effects of inflammation. Would make use of receptors which are able to bind to 1)IgE molecules and 2) the allergen particles themselves.
Gastric Inflammation
Treatment and prevention of H. pylori(stomach ulcer) - engineer a B. subtilis that can live and grow happily in stomach acidity (pH2) - an acidophilic strain will also be needed for the heavy metal trapping.
Skin repairer
Using the production of hyaluronic acid (HA) an important glycosaminoglycan which is found in synovial fluid, extracellular matrix and very important in wound healing. It was found by Widner et al. 2005 that the HasA gene for Hyaluronan synthase could be expressed successfully in B. subtilis. It could maybe be put into a plaster or gauze used to dress wounds? (The bacteria should be friendly to the human body and generate a growth factor like HA or another product to help skin cells grow; or maybe generate skin like material which can grow together with healthy skin)
([http://www3.interscience.wiley.com/journal/121633568/abstract?CRETRY=1&SRETRY=0 Article])Idea came up in meeting 19/02/09- using a bacterial lawn to produce antibiotics within a plaster to protect a healing wound- OR- to produce S. aureus signal proteins which would prevent communication between S. aureus thus preventing infection.
Cosmetic bacteria
Can we use the bacteria to fill up the wounds, scratches, wrinkles etc. for a couple of hours.
Sticky bacteria
Again for filling or sticking items for example to a wound.
Hair / filament producing bacteria allied to skin repair idea - may provide scaffold.
B. subtilis produces flagella. can we engineer it to produce large filaments of eg keratin which will stabilise a wound dressing?
Bacterial microscopy
Can they magnify very small objects for us?
MVC
Implemantation of model view controller software pattern to bacteria. One group of colony is responsible only for the view,via fluorescent proteins etc, one gives commands to model poulation. At some point we may decide to add another command type population without breaking the whole pattern because all the command type bacteria have the same interface. This could also be implemented in a different way as service oriented bacteria having bacteria population that only does one job at a time. Another colony uses the services to do a certain task. ([http://www.pnas.org/content/104/5/1456.full Article 1]) ([http://www.ncbi.nlm.nih.gov/pubmed/18675483 Article 2])
Timed Germination
Can we engineer bacteria to start germination at a specific time.
They correspond to signals to start or stop germination without the nutrition
([http://www.nature.com/nrmicro/journal/v7/n1/full/nrmicro2060.html Article 1])
([http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WSN-4TT8K22-J&_user=224739&_rdoc=1&_fmt=&_orig=search&_sort=d&_docanchor=&view=c&_acct=C000014659&_version=1&_urlVersion=0&_userid=224739&md5=3c2b44fd89005cb37a6ed55b08ef230a Article 2])
Path finding
Simulating the ant colony ([http://en.wikipedia.org/wiki/Ant_colony_optimization Article]). Bacteria will move intelligently tracking the pheromenes that are left by the others ([http://portal.acm.org/citation.cfm?id=1389095.1389115 Article]).
Or safe walk. Others will tell if it is safe to continue in a direction
King bacteria. Other bacteria will guide king bacteria on a safe path
Chaperone producer
Depending on the conditions, some chaperiones like Hsp70, Hsp60 will be secreted. It might be used to cure Alzheimer disease ([http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2533148 Article]).
Glucose sensing bacteria
Bacteria capable of sensing the level of glucose in a blood sample. This could be a cheap way of testing for glucose level in blood sample.
Freezer
To store nutrients using sporulation depending on the input functions and release them when needed upon a forced germination
SPOT THE ROT
Spores go red on germination when conditions go from v. cold to warm to indicate spoilage on food or medical product packaging.
Bacterial automation
Using electronic sensors to connect computer directly to start a process for the bacteria. E.g Start DNA uptaking. The output function of electronic circuit should match to the input of the bacteria
Bacterial tattos
Using bacteria to have temporary tattos.
Bacterial compass
Can we use bacteria to find our direction? Can we use magnetosomes for this purpose? ([http://www.scientificblogging.com/news_releases/magnetic_crystals_are_bacterial_compass_say_researchers Article])
Bacterial sensor which tells you how it "feels" by the rate of flashing. Maybe responding to environmental stress.
It would be much easier to use than having to measure the intensity of fluroescence. Or maybe we could have a traffic light effect.
Back in the days when I did ecotoxicology (late 80's early 90's) our dream was for a fish on a stick, you just dip it in the water and it tells you how it feels!
The closest we had then was a system called Microtox based on a phosphorescent marine bacterium Vibrio fischeri. There are tons of data relating the response of Microtox to environmental factors.
Cleaner bacteria
Eco-friendly, producing enzymes,proteins for cleaning purposes (toothpaste???)([http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V24-4VBM49J-3&_user=224739&_rdoc=1&_fmt=&_orig=search&_sort=d&_docanchor=&view=c&_searchStrId=950885605&_rerunOrigin=google&_acct=C000014659&_version=1&_urlVersion=0&_userid=224739&md5=c747408865efc0bec1a88605aa318756 Article])
Eco-friendly bacteria produce celullase in large quantities to aid bio-fuel production see

Bacteria gum
It is a little bit like bacteria toothpaste, to prevent decay of teeth, it can generate sweet material when we chew it.
Rock bacteria
Bacteria can sense sound and use sound to communicate with others, can we make bacteria change it's color or other behaviour according to the different sound ([http://www.jstage.jst.go.jp/article/jgam/44/1/44_49/_article Article]).
Finger sensor
Using the pressure sensitivity, perhaps a fingerprint impression could be made in a bacterial lawn, with varying pressures from the grooves of the fingerprint giving different responses.
World with bacterial communities as the countries
Bacteria populations that can speak to each other but also have interactions with other populations. Each population trade with others and live in a world.
