The world is changing and so are the energy needs of humanity. Fossil fuels aren’t endless and it is clear that a transition to clean sustainable energy has to be made. We believe synthetic biology can be an important catalyst in this process. Specifically, we engineer a Bacillus subtilis biofilm to function as a cation exchange membrane. Such a membrane can be used in Reverse Electrodialysis (RED), a technique to generate energy where salt and fresh water mix, for example where rivers flow into the sea. We call this application of the bacterial biofilm Blue Bio Energy. It is estimated that it can meet 4-7 % of the world energy demand.

Biofilm ion selectivity
Cras rutrum lobortis ante nec ornare. Duis laoreet, eros vel imperdiet vehicula, justo est finibus sapien, nec cursus justo purus sit amet nisl. Fusce ac lorem vel magna pellentesque convallis et sit amet nulla. Pellentesque augue nulla, gravida non ante vel, hendrerit rutrum nulla. Nunc malesuada sapien volutpat nibh faucibus.

Rigidity of the biofilm
Ut tortor urna, malesuada a nisi ac, suscipit sagittis lorem. Cras maximus, diam nec finibus venenatis, leo ante efficitur mauris, rhoncus condimentum metus ipsum et lectus. Quisque sapien felis, sodales a tempus sit amet, feugiat sit amet felis.

Integrate bacteria into local environment
Cras pellentesque rutrum est quis ultrices. Phasellus sodales eros in purus auctor eleifend. Proin sit amet odio non dolor commodo viverra. Nulla a urna finibus, posuere purus sed, posuere dui. In elit nunc, pretium non mi sit amet, blandit gravida nibh. Donec quis arcu dui. Sed aliquam fermentum nisl nec auctor. Integer felis magna, mollis eu facilisis non.

Self-sustainability
Curabitur condimentum hendrerit eleifend. Sed fermentum ornare faucibus. Cras justo orci, malesuada in venenatis eget, pharetra a orci. Duis odio nunc, faucibus at pulvinar mattis, luctus vitae turpis. Phasellus id augue elementum eros sodales facilisis non quis elit.

And Yes
Donec ut interdum diam. Nullam malesuada erat vitae orci efficitur, ac finibus augue sollicitudin. Curabitur ornare augue at viverra commodo. Fusce efficitur neque dolor, nec rhoncus mauris mollis eget. Donec faucibus semper felis, quis feugiat dolor scelerisque sit amet. Morbi hendrerit sem quam, nec pharetra metus finibus vitae..
