Microbial carbon and nutrient utilization strategies in the Outokumpu drill hole at (a) 600, (b) 1500 and (c) 2300 m depth predicted from MG-RAST annotations of 454 shotgun metagenomes. Pathways that differed statistically significantly (P<0.05) between metagenomes are indicated in bold. Solid lines indicate pathways from which all genes were detected in the respective metagenomes. The lithology column represents the drill hole and shows rock types intersected by the drill hole (blue: metasedimentary mica schists; green and orange: ophiolite-derived serpentinites, skarn rock and quartz rock; pink: pegmatitic granite).
