|Shenzhen_SFLS is the first time to take part in iGEM High School Competition and 2013 is the first year there are 4 chinese teams entered the lists. SFLS is one of the top high schools in Shenzhen and there are all the best students in Shenzhen, China. With the guidance from BGI-Shenzhen, we aim to build fantastic and useful genetic circuits.

Shenzhen_SFLS iGEM team was set up in October 2012, after the iGEM Collegiate Division in Asia. The team leader watched the jamboree and he was deeply attracted by the great game. He found 7 students who followed him overcame the difficulties and obstacles. In october 2013, they went to BGI to study how to make a gene circuit。

===Project===
+
-
Pollution caused by development and expansion of human society is an enormous problem that has been discussed for centuries. The negative effects of ruining the environment can be seen readily all around the world, especially in nations growing as rapidly as China. One common type of pollution that has been increasing with the advent of large-scale industrialization is known as eutrophication. In eutrophication, water supplies experience a heightened concentration of phosphorus and nitrogen due to human activity. One consequence of such a shift in balance is an increase in the biomass of phytoplankton, resulting in a higher incidence of toxic mutants and a lower concentration of oxygen in the water, killing other life present in the pond and severely changing local ecosystems and fishing economies.　
+
-
 
+
-
One clear example of eutrophication can be the 2008 Beijing Olympic games.The enormous growth of China’s industrialization somehow created sharp problems for the environment. Waste water from factories contains high concentration of phosphate and nitrogen. These elements gathered in water and finally created water-blooms that caused a huge catastrophe. The windsurfing games, however, were terribly affected by the water-blooms , costing huge amount of money of the China Official.
+
-
 
+
-
Our home city of Shenzhen, China, is a relatively new city undergoing large amounts of growth due to its status as a special economic zone. As the population increases, pollution worsens, especially in locations deemed desireable by families. In Dameisha, one subdistrict of Shenzhen, the eutrophication seen in the water at the beach has driven tourists away, effectively limiting the economic growth the area could otherwise be experiencing. At SFLS, we therefore decided that our project should concern itself with eutrophication. Finally we've decided to use bioengineering as a tool to limit the damage humans will inevitably cause to their own water supplies.
+
-
 
+
-
Our project involves the creation of two connecting devices, Devices 1 and 2. Device 1 contains a promoter which will be induced by phosphate starvation, supressors lac or tetR, and an RFP system. This device is activated in the absence of phosphate and acts as a sensor. It serves to let us know phosphate levels are safe by prompting host bacteria to emit a red fluorescence.
+
-
 
+
-
Device 2, on the other hand, includes a promoter which is limited by the suppressor protein featured in Device 1, which means that Device 2 is not active while Device 1 operates. Most importantly, it includes a coding sequence called PPK that is key in digesting phosphate and a GFP player that allows the bacteria to emit a green fluorescence while it is doing so. We've also included an LVA element that quickly dampens green fluorescence production once Device 2 has successfully cleared the surrounding water of sufficient amounts of phosphate and begins to shut down, allowing the red fluorescence produced by Device 1 to shine uninhibited and making it easy for us to know we've successfully purified the water.
+
-
 
+
-
In a nutshell, when there is too much phosphorus in the water, Device 1 won't be active. This allows Device 2 to operate unsuppressed, and our bacteria will produce PPK, which allows the bacteria to digest phosphate and emit a green fluorescence. When the concentration of phosphate decreases, Device 1 will be activated, stopping Device 2's activities via a suppressor protein and allowing the bacteria to glow red via RFP. Our product is automatic and environmentally friendly!

-
What safety precautions did your team take? Did you take a safety training course? Were you supervised at all times in the lab?
+
-
Safety Questions
+
-
1. Would any of your project ideas raise safety issues in terms of: researcher safety, public safety, or environmental safety?
+
-
No. Before doing the experiments, all of our team members have already listened to the laboratory safety talk given by advisor. Our design is based on the commonly used nonpathogenic E. coli K.12strain and genes we manipulated are original genes in E. coli. .To guarantee the safety of our researchers and lab personnel, we especially emphasized protection while doing experiments related to bacteria, toxic reagents, fire or electricity. All of us were required to clean up the experiment area to ensure that there was no harmful things left.

-
===Backgrounds===
+
-
Too much phosphorus in the body can be just as harmful as having too little. Likewise, too much phosphorus in lakes and streams can have negative side effects on the surrounding environment, it will make the water eutrophication.
+
-
 
+
-
Water eutrophication can be human-caused or natural. Untreated sewage effluent and agricultural run-off carrying fertilizers are examples of human-caused eutrophication. However, it also occurs naturally in situations where nutrients accumulate (e.g. depositional environments), or where they flow into systems on an ephemeral basis. Eutrophication generally promotes excessive plant growth and decay, favouring simple algae and plankton over other more complicated plants, and causes a severe reduction in water quality. Phosphorus is a necessary nutrient for plants to live, and is the limiting factor for plant growth in many freshwater ecosystems. The addition of phosphorus increases algal growth, but not all phosphates actually feed algae.[2] These algae assimilate the other necessary nutrients needed for plants and animals. When algae die they sink to the bottom where they are decomposed and the nutrients contained in organic matter are converted into inorganic form by bacteria. The decomposition process uses oxygen and deprives the deeper waters of oxygen which can kill fish and other organisms. Also the necessary nutrients are all at the bottom of the aquatic ecosystem and if they are not brought up closer to the surface, where there is more available light allowing for photosynthesis for aquatic plants, a serious strain is placed on algae populations. Enhanced growth of aquatic vegetation or phytoplankton and algal blooms disrupts normal functioning of the ecosystem, causing a variety of problems such as a lack of oxygen needed for fish and shellfish to survive. The water becomes cloudy, typically coloured a shade of green, yellow, brown, or red. Eutrophication also decreases the value of rivers, lakes, and estuaries for recreation, fishing, hunting, and aesthetic enjoyment. Health problems can occur where eutrophic conditions interfere with drinking water treatment.

-
===Human Practices===
+
-
Even though our human practises have just started. We have already done something.
+
-
We invited the school's TV&Broadcast Center to shoot an advertising video for our team.
+
-
This can make contribution to us and let more people know iGEM, as well as Synthetic Biology.
+
-
 
+
-
More human practises are preparing. Please do look forward to it.
