                    <p>Heavy metals (Cu2+, Cd2+, etc.) influence every aspect of human life. Although they are important to chemical, medical, and manufacturing industry, exposure to them has caused lots of hazards to humans.</p>
  
                  <ellipse transform="matrix(0.9781 -0.2079 0.2079 0.9781 -11.9408 31.1644)" fill="none" stroke="#979797" stroke-width="0.2" stroke-miterlimit="10" cx="142.284" cy="72.387" rx="10" ry="25"/>
+
<p>With the rapid development of global industrialization, heavy metal pollution has become a severe problem threatening everyone's health. Thanks to the global collaboration with more than 20 teams involved, our principals for human practice and model has completed a world map for some heavy metals' pollution. The result illustrates a serious situation we are faced with.</p>

<p>After actuality investigation with government, companies and NGOs, three key questions have been summed up. How can microorganism survive from a relatively high concentration of heavy metals? How can we separate different metals with fewer reactions? How can we monitor the water quality after treatment in real time?</p>
  
                  <ellipse transform="matrix(0.9613 -0.2756 0.2756 0.9613 -60.8751 60.7838)" fill="none" stroke="#979797" stroke-width="0.2" stroke-miterlimit="10" cx="185.812" cy="246.966" rx="10" ry="25"/>
+
<p>For these questions, we chose to use a brand-new strategy, synthetic life, to answer them. Within the framework of <a href="http://syntheticyeast.org/sc2-0/"> Sc2.0</a> project, scientists from all over the world work together to build the world's first synthetic eukaryotic genome - <i>Saccharomyces cerevisiae</i>'s genome. Chinese team from Tianjin University has completed two synthetic chromosomes, and we are very lucky to use the synthetic yeast to solve these questions.</p>

+
<p>We used a particular genome evolution system, SCRaMbLE (Synthetic Chromosome Recombination and Modification by LoxP-mediated Evolution), to rapidly obtain the budding yeast with tolerance of high concentration of heavy metals. To answer the second question, we also boldly and creatively designed a orthogonal switcher with the SCRaMbLE system, based on the change of yeast's mating type which determine the sexuality. We also improved and created many parts to build a biosensor for Cu ions with higher sensitivity and wider response range.</p>

/* OVERRIDE IGEM SETTINGS */

Description


Heavy metals (Cu2+, Cd2+, etc.) influence every aspect of human life. Although they are important to chemical, medical, and manufacturing industry, exposure to them has caused lots of hazards to humans.

With the rapid development of global industrialization, heavy metal pollution has become a severe problem threatening everyone's health. Thanks to the global collaboration with more than 20 teams involved, our principals for human practice and model has completed a world map for some heavy metals' pollution. The result illustrates a serious situation we are faced with.

The pollution of cadmium worldwide

After actuality investigation with government, companies and NGOs, three key questions have been summed up. How can microorganism survive from a relatively high concentration of heavy metals? How can we separate different metals with fewer reactions? How can we monitor the water quality after treatment in real time?

For these questions, we chose to use a brand-new strategy, synthetic life, to answer them. Within the framework of Sc2.0 project, scientists from all over the world work together to build the world's first synthetic eukaryotic genome - Saccharomyces cerevisiae's genome. Chinese team from Tianjin University has completed two synthetic chromosomes, and we are very lucky to use the synthetic yeast to solve these questions.

We used a particular genome evolution system, SCRaMbLE (Synthetic Chromosome Recombination and Modification by LoxP-mediated Evolution), to rapidly obtain the budding yeast with tolerance of high concentration of heavy metals. To answer the second question, we also boldly and creatively designed a orthogonal switcher with the SCRaMbLE system, based on the change of yeast's mating type which determine the sexuality. We also improved and created many parts to build a biosensor for Cu ions with higher sensitivity and wider response range.

Let's get started with Design and Demonstrate.
