Modulation of sulfate permease for photosynthetic hydrogen production

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. The alga is cultured in a sealed environment in a liquid or solid 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.

Regulatory Factors Controlling Oil Biosynthesis In Microalgae And Their Use

The production of transgenic plant oils is described by transfecting plant host cells with heterologous transcription inducers. Such inducers are specific for endogenous biosynthetic plant oil genes, such that the inducers induce an overexpression of the plant oil genes. The overexpressed gene product (i.e., for example, diacylglycerol transferase) thereby results in a increased intracellular production of a plant oil (i.e., for example, triacylglycerol). In one embodiment, the transfected plant host cell can be a plant algae species (i.e., for example, Chlamydomonas reinhardtii).
