Anastasios Melis

Anastasios Melis is a Greek biologist at the University of California, Berkeley who is researching the possibility of creating hydrogen from algae. Hydrogen power is considered one of the key ways of producing electricity without continuing to use up fossil fuels. The added bonus of using algae in this way is that they could consume carbon dioxide in the atmosphere.

In 1997 Professor Anastasios Melis discovered, after following Hans Gaffron's work, that the deprivation of sulfur will cause algae to switch from producing oxygen to producing hydrogen. The enzyme, hydrogenase, he found was responsible for the reaction.
