MODULATION OF SULFATE PERMEASE FOR PHOTOSYNTHETIC HYDROGEN PRODUCTION

Title:

MODULATION OF SULFATE PERMEASE FOR PHOTOSYNTHETIC HYDROGEN PRODUCTION

Document Type and Number:

WIPO Patent Application WO2003067213

Kind Code:

A3

Abstract:

Sustained hydrogen production is obtained by the culturing of a genetically modified algae, where the ability of the chloroplasts to intake sulfate is reduced or eliminated compared to wild-type algae (Figure 6). The genetically modified algae are cultured in a sealed environment in a liquid or solid culture medium that contains sulfur, and hydrogen is generated continuously. Alternatively, the algae may be cultured in the presence of bacteria that also produce hydrogen gas. The hydrogen produced can be collected and used as a clean energy source.
