Project Description

Overview

For commercial shellfish farmers and recreational hunters alike, marine biotoxins pose a significant threat to health and welfare. With this project, we aim to create an inexpensive and easy-to-use test kit for the detection of the shellfish toxin okadaic acid using engineered yeast strains and DNA aptamers on a paper device. We also hope that this project paves the way for a new class of biosensors capable of detecting a wide range of small molecules.

What is the context of this research?

Marine toxins are an increasing problem in Washington State waters. Produced in high concentrations by microorganisms during algae blooms, they are ingested by filter-feeding shellfish, causing illness and death in human consumers. Biotoxins are also difficult to detect; contrary to popular belief, algal blooms are not always the striking crimson of “red tides.” Thus, blooms may not be discovered until after a poisoned shellfish is found. The Washington State Department of Health and commercial shellfish farmers conduct periodic surveys of local beaches to catch contaminations early, but these methods are costly, time-consuming, and not always effective. This can especially pose a dilemma for individual shellfish hunters, who do not have the resources to screen their shellfish for toxins.

What is the significance of this project?

Our project aims to combine the emerging fields of synthetic biology and paper diagnostics to create an affordable, accessible, and accurate diagnostic test kit that would allow farmers and the public to test shellfish for common biotoxins. This “lab on a strip” will be a critical step forward in marine toxin detection, as it will cut nearly 20 hours off the time needed to obtain results, allowing farmers to screen at a lower cost and empowering individual hunters to confirm the safety of their shellfish. This is also the first project to attempt to grow yeast on a paper device, and if successful, could open the door to a wide range of similar biosensors. Such sensors would have applications in medicine, food, and the environment worldwide.

What are the goals of the project?

1. Develop a paper microfluidic device that houses yeast; it will provide adequate nutrients for cell growth, but will also be freeze-dried for long-term storage.

2. Create a detection system for the plant hormone auxin in which yeast produce a color in response to an auxin input; test it in cells growing on normal media.

3. Clone each part from this system into standard plasmids for submission to BioBrick registry.

4. Show that when grown on paper, yeast can reliably detect auxin.

5. Use aptamers (short DNA sequences) to detect for okadaic acid, a shellfish toxin that causes Diarrhetic Shellfish Poisoning.

6. Show that the aptamer system for detection can be implemented on our paper platform and reliably detect for okadaic acid.

7. Improve safety of shellfish consumers in the NW and the world!

See tips on how to edit your wiki on the Template Documentation page.

Templates

This year we have created templates for teams to use freely. More information on how to use and edit the templates can be found on the Template Documentation page.

Tips

This wiki will be your team’s first interaction with the rest of the world, so here are a few tips to help you get started:

• State your accomplishments! Tell people what you have achieved from the start.
• Be clear about what you are doing and how you plan to do this.
• You have a global audience! Consider the different backgrounds that your users come from.
• Make sure information is easy to find; nothing should be more than 3 clicks away.
• Avoid using very small fonts and low contrast colors; information should be easy to read.
• Start documenting your project as early as possible; don’t leave anything to the last minute before the Wiki Freeze. For a complete list of deadlines visit the iGEM 2015 calendar
• Have lots of fun!

Inspiration

You can also view other team wikis for inspiration! Here are some examples:

Uploading pictures and files

You can upload your pictures and files to the iGEM 2015 server. Remember to keep all your pictures and files within your team's namespace or at least include your team's name in the file name.
When you upload, set the "Destination Filename" to Team:YourOfficialTeamName/NameOfFile.jpg. (If you don't do this, someone else might upload a different file with the same "Destination Filename", and your file would be erased!)
