Biohydrogen- Worth a closer look.

I spent today collecting new samples of strains of fast growing microalgae with Travis Leogrande one of our field researcher.

We are looking into a very insidious form of algae to "repurpose".

We also came across this interesting snippet courtesy of the Wikipedia:
"Algae can be grown to produce biohydrogen. In 1939 a German researcher named Hans Gaffron, while working at the University of Chicago, observed that the algae he was studying, Chlamydomonas reinhardtii (a green-alga), would sometimes switch from the production of oxygen to the production of hydrogen.[7] Gaffron never discovered the cause for this change and for many years other scientists failed to repeat his findings. In the late 1990s professor Anastasios Melis, a researcher at the University of California at Berkeley, discovered that if the algae culture medium is deprived of sulfur it will switch from the production of oxygen (normal photosynthesis), to the production of hydrogen. He found that the enzyme responsible for this reaction is hydrogenase, but that the hydrogenase lost this function in the presence of oxygen. Melis found that depleting the amount of sulfur available to the algae interrupted its internal oxygen flow, allowing the hydrogenase an environment in which it can react, causing the algae to produce hydrogen. [8] Chlamydomonas moeweesi is ... a good strain for the production of hydrogen.

We believe we can create a similar effect from Lyngbya sp. but we need further consultation. We are going to attempt to verify some information with a USF professor.

I have not yet spoken with him, but intend on contacting him.

We also believe we are a good candidate for a particular grant with our Non-profit
side of Venturi Industries.
