BHP Patent Landscape

This page will have links to many of the patents which cover the BHP. We will start with the basics such as those surrounding hydrogenase and the various model organisms and then continue by addressing patents for each of the strategies outlined by Royd.

There is an idea that increasing the rate that protons are allowed out of the thylakoid membrane will increase the efficiency of H2 production. I don’t know much about it yet, but there is a newly published patent
