Patent ID: 8753837

Claim:
A method for photobiological production and harvesting of ethanol comprising growing a transgenic oxyphotobacterium or oxyphotobacterial cells in a liquid medium, wherein the oxyphotobacterium or oxyphotobacterial cells are genetically engineered with a set of DNA constructs to express a set of enzymes consisting of NAD-dependent glyceraldehyde-3-phosphate dehydrogenase comprising SEQ ID NO: 40 or 53, pyruvate decarboxylase, and NAD(P)H-using alcohol dehydrogenase comprising SEQ ID NO: 7 or 17 that act on an intermediate product of the Calvin cycle and convert the intermediate product into ethanol using photosynthetic reducing power NADPH; and recovering ethanol from said liquid medium with a special greenhouse distillation system.
