Figure 3From: Could petroleum biodegradation be a joint achievement of aerobic and anaerobic microrganisms in deep sea reservoirs? Total ion chromatograms (GC-MS) of hydrocarbon fractions from oils (Pampo Sul Field, Campos Basin) undergoing in vitro (aerobic consortium, 3C; anaerobic consortium, 3D; mixed aerobic and anaerobic consortium, 3E) and in reservoir (level 1-2, 3A; level 4, 3B) biodegradation.
