Time courses of anaerobic, denitrifying growth of C. defragrans strains 65Phen (●), Δldi (□), Δldi comp (■), Δgeo A (▵) and Δgeo A comp (▴) on different carbon sources, namely (A) 4 mM α-phellandrene, (B) 4 mM limonene, and (C) 4 mM β-myrcene. Negative controls without inoculum or without substrate did not show an increase in turbidity (data not shown).
