Our Goal and Process of the ExperimentOverall Target: Decompose dioxin in the plant and the microorganisms.Change the characteristics on the microorganisms, and make it just like the plant cells, so that it will not be rejected.Increase microorganisms ability of defensing the rejectionExperiment1

Microbiologically Degrade the Dioxin,

Through the Use of Symbiosis between Microorganism and Plants Increase the Efficiency of the Degradation Process

InnovationGreenEssentialityAdvantagesIt can completely decompose the pollution, instead of just separating it and storing it.It is the first time of artificially making two types of organisms symbiotic.1.The carbon dioxide produced by the organisms can be used during the process of photosynthesis.

2.Our plant can be planted on the polluted land which used to be barren, and the plant can do photosynthesis and something else good for the environment.Thanks for Dr. Xu Hao, Dr. Cai, Ms. Liu Ming, and our group members: Wang Chengwei, Yang Anrui, Li Yuanlin, Qi Yaxin.

Thanks for listening!

The schema of restore the ecotope in smoggy days ASK:Why you do this?ANSWER:Because now ,Smog influence a lot of first-tier cities in China as well as many cities all over the world.And everybody wants to meke the air fresh!ASK:So what's your ideal?ANSWER:I will show you.ASK:So have you got any trouble?ANSWE:Yes,of course!I cannot save sunlight.But I have already thought for it!Here we go!

I want to change the CO2 to the O2! And now we konw photosynthesis. And we also know if we want to chang CO2 to o2,we must find a way to find light. Sunlight is the best way to do phootosynthesis! But how could we find sunlinght? So we can save it! If we have this skill to make sunlight slowly or stop it. The we can make the air fresh in our class room!
