By searching for genetic sequences similar to regA in the burgeoning databases of genes that now exist, they found one in a unicellular alga called Chlamydomonas reinhardtii.
The C. reinhardtii chloroplast foreign gene expression system has been utilized successfully to produce a variety of recombinant proteins including human therapeutic proteins.

Organisms other than cyanobacteria, such as the alga Chlamydomonas reinhardtii, also produce hydrogen at similar rates, says Olaf Kruse of Bielefeld University in Germany, who works with the species.
