  abstract = {{T}here is growing evidence that microbial populations associated with rocks may be involved in weathering processes; in particular they may play a role in the degradation of fossil organic carbon widely present in sedimentary rocks. {I}n this study, we investigate the microbial diversity associated with two organic-rich rocks exhibiting contrasted organic chemical structure: a typical type {I} aliphatic carbon-rich kerogen ({A}utun shale) and a coal rich in aromatic carbon ({G}raissessac coal). {I}n both rocks, the mineralogy and the geochemistry of the organic matter were investigated. {M}oreover, the microbial diversity associated with these rocks was characterized using bacterial 165 r{RNA} gene analysis. {I}n the {A}utun shale, one dominant species is observed ({R}alstonia) whereas a larger microbial diversity is retrieved from the {G}raissessac coal. {A}ltogether, we conclude that potential hydrocarbonoclastic microorganisms detected by the presence of nag-like genes potentially encoding dioxygenase may be associated with a possible biodegradation of fossil organic carbon in the two samples. {W}e conclude that under favorable conditions, aerobic biodegradation could occur and oxidize a minor fraction of these two different kerogens using a similar enzymatic process.},
