Summary The oxidation of branched C5-dicarboxylates has been studied with microorganisms obtained from enrichement cultures with each of these acids. Bacteria grown on itaconate, mesaconate or methylsuccinate oxidize most of these compounds rapidly; (+) citramalate is oxidized 2–4 times as rapidly as (-) citramalate; and citraconate only feebly. Citraconate-grown cells do not oxidize itaconate and oxidize feebly mesaconate and methylsuccinate; they oxidize (-) citramalate 3–4 times faster than (+) citramalate. Cell-free extracts of various strains grown on different C5-dicarboxylates contain pronounced mesaconase activity, varying amounts of citraconase and hardly any itaconase activity.
