Nice old review on aromatic degradation. I think there are more recent references available

Decent review article talking about natural degradation pathways on a global level; doesn't go into specific metabolism much. Does cover redox potential and real challenges in the field, though.

Very old review outlining some states of hydrocarbon degradation in the environment. Interesting old facts like number of plasmids typical (2.5), mostly bacterial in nature, utility of dispersants, and physical states needed for degradation.

Nice review of known anaerobic aromatic degradation pathways. Most seem to shuttle things through benzoyl-coA and b-oxiation via acetyl-coA
