Scanning electron microscopy of Corynebacterium glutamicum MG cells in phosphate-limiting continuous culture. 0.1 h -1 - Source:4Aerobic heterotroph
Corynebacterium are mycolic acid-containing actinomycetes and a member of the mycolata. Their association with highly hydrophobic members of this group, has implicated them as foamers in activated sludge, however this has not been shown for the genus 5. Species belonging to Corynebacterium are chemoorganotrophs with a fermentative metabolism 6. Growth for many species occurs under facultatively anaerobic conditions, however some may be strictly aerobic 6. Denitrification has been shown by some species in pure culture, with the ability to reduce NO3- to N2O via NO2- 7 8. Polyphosphate accumulation 9 4 and formation 10 has been demonstrated by some species under phosphate limiting conditions, however this has not been determined in situ. Similarly, glycogen accumulation has also been shown in C. glutamicum under phosphate limitation 4. Cell morphology of the genus is short to medium length rods, which may appear straight or slightly curved 6.
