The enzyme D-lactate dehydrogenase from Megasphaera elsdenii catalyzes the oxidation of D-lactate to pyruvate, with an electron-transferring flavoprotein serving as the ultimate oxidant. Its reaction is similar to the first step of the lactate oxidase reaction, but the two enzymes use enantiomeric substrates, leading to the proposal that the two enzymes utilize similar mechanisms but bind their substrates in opposite orientations (Ghisla et al., 1976). Incubation of o-lactate dehydrogenase with d-13 leads to enzyme inactivation with a partition ratio of 5 (Olson et al., 1979). A novel pink chromophore formed concomitantly...

MEferm is assumed to be 0.1 ME for silages and 0.05 ME for brewery and distillery by-products, and MEfat is 35 MJ/kg. The assumption made here for silage must be suspect. The major fermentation product in well-made silages is lactate, and there is evidence that several rumen bacteria, notably Megasphaera elsdenii (see Table 8.3 in Chapter 8), are able to utilise lactate with the production of propionate. The microbial crude protein yield (g) is calculated as follows ...
