✦ Synopsis

13 Alternative energy supplies (biofuels and bioconversion energy)

Lack of B875 complex following in-frame deletion of pufBA (mutant PUF1) not only slowed photoheterotrophic growth but also decreased H2 production, indicative of the essential requirement of the complex for LH process. However, the pucBA-deleted mutant, PUC1 lacking of B800 850 complex, increased H2 production in comparison with its parental cell by approximately twofold, given irradiated with light (10 W/m 2) saturating the growth of wild type. The H_~ production of PUC1 did not increase in proportion to the light intensity, which is also observed with wild type. Thus, the authors suggest that light is not limited for the H2 production of the cells under the experimental conditions employed in this work, but the cellular energy to be used for the formation of B800-850 complex may flow into the metabolism leading to the H2 production in PUC1.
