Biodegradation involves microbes which occur at shallow depths (Connan, 1984), near faults or near unconformities, degrade hydrocarbons (consuming parafins and lighter ends) leaving behind napthenes and asphaltenes (gas chromatograms show parafin spikes missing). Surface (meteoric) water is the main vehicle that brings microbes in contact with pooled hydrocarbons.
Microbes that can metabolize oil include fungi, yeast, and both aerobic and anaerobic bacteria, with aerobic bacteria considered to be the most effective of the group.
