Beschreibungen/Notizen

• The photoheterotrophic H₂ production of Rhodobacter sphaeroides was significantly increased through disruption of the genes coding for uptake hydrogenase and poly-β-hydroxybutyrate (PHB) synthase (Lee et al., Appl. Microbiol. Biotechnol. 60: 147-153, 2002). In this work, we further removed the B800-850 light-harvesting (LH) complex from the strain and found an increase in H₂ production at the light-saturating cell growth (greater-than or equal to 10 Watts [W]/㎡). Neither the mutant nor the wild-type produced more H₂ at the brighter light.
