Figure 1From: Combined inactivation of the Clostridium cellulolyticum lactate and malate dehydrogenase genes substantially increases ethanol yield from cellulose and switchgrass fermentationsDiagram of the mdh and ldh genes with markerless intron insertions in the sense orientation. The 933-bp mdh gene (Ccel_0137) contains an intron inserted between bases 216 and 217. The 951-bp ldh gene (Ccel _2485) contains an intron inserted between bases 516 and 517.Back to article page
