Simplified schematic representation of ethanol and biomass formation by an engineered strain of Saccharomyces cerevisiae by heterologous expression of genes encoding the Calvin-cycle enzymes PRK and RuBisCO. Black: biosynthetic reactions with a net input of ATP and a net production of CO2 and NADH. Blue: redox-neutral conversion of glucose to ethanol by glycolysis, pyruvate decarboxylase and alcohol dehydrogenase. Blue: NAD(P)H-dependent conversion of acetaldehyde into acetate. Orange: non-oxidative pentose phosphate pathway, heterologously expressed PRK/RuBisCO pathway and subsequent NADH-requiring ethanol formation. Grey: native glycerol reduction pathway
