Project background

The digestive tract of earthworm is a small "culture room" for the growth and reproduction of many bacteria and actinomycetes. When the earthworm ingests organic matter containing a large number of microorganisms, microorganisms and nutrients are finally discharged into the earthworm dung through the digestive tract, which makes the earthworm feces rich in bacteria, actinomycetes, fungi and other microbial groups. Because of the rich nutrients in the earthworm manure, the number of bacteria discharged from the earthworm dung will double in the first week. The rich nutrients in earthworm manure and the large surface area brought by the aggregate structure provide excellent environmental conditions for the stable survival and mass reproduction of microorganisms. Therefore, the earthworm feces with vigorous microorganisms become the transmission center of soil microorganisms and the decomposition center of soil organic matter. In addition, earthworms absorb a large amount of organic matter in the soil during their life, and then further condense to form humus under the action of phenol oxidase secreted by intestinal cells and microbial secreted enzymes after initial decomposition. Therefore, vermicompost also contains a lot of humus. The inherent colloidal properties of humus can improve the structure of soil, which is conducive to aeration, water retention and buffer capacity of soil. At the same time, a large number of studies have shown that humic acid itself is a strong adsorbent, which can adsorb soluble heavy metals and affect the bioavailability of heavy metals.

Welcome to iGEM 2020!

Your team has been approved and you are ready to start the iGEM season!

Before you start

Please read the following pages:

Styling your wiki

You may style this page as you like or you can simply leave the style as it is. You can easily keep the styling and edit the content of these default wiki pages with your project information and completely fulfill the requirement to document your project.

While you may not win Best Wiki with this styling, your team is still eligible for all other awards. This default wiki meets the requirements, it improves navigability and ease of use for visitors, and you should not feel it is necessary to style beyond what has been provided.

Uploading pictures and files

You must upload any pictures and files to the iGEM 2020 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 T--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!)

Wiki template information

We have created these wiki template pages to help you get started and to help you think about how your team will be evaluated. You can find a list of all the pages tied to awards here at the Pages for awards link. You must edit these pages to be evaluated for medals and awards, but ultimately the design, layout, style and all other elements of your team wiki is up to you!

Editing your wiki

On this page you can document your project, introduce your team members, document your progress and share your iGEM experience with the rest of the world!

Use WikiTools - Edit in the black menu bar to edit this 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 2020 calendar
  • Have lots of fun!
