  abstract = {{D}ue to increasing atmospheric pollution, it has become highly important to investigate how anthropic chronic contaminations may affect ecosystem functioning. {T}o explore the effect of polycyclic aromatic hydrocarbons ({PAH}s) on indigenous microbial activities, anthracene was used as a model {PAH} in a mesocosm experiment with {P}inus halepensis litter from the {M}assif of {M}arseilleveyre ({M}arseille, {F}rance). {T}he effects of anthracene on microbial activities were followed after 1- and 3- month incubations by: {C}atabolic {L}evel {P}hysiological {P}rofile ({CLPP}) using {ECO} and {FF} plates and four enzyme activities (cellulase. beta-glucosidase, acid phosphatase and lipase), {M}oreover the chemical variations in organic matter were evaluated by solid-state {C}-13 {NMR} and {C}/{N} ratio. {T}hese experiments revealed an increase in cellulase, beta-glucosidase and phosphatase activities and a decrease in lipase activities after a 3-month incubation in the presence of anthracene. {P}rincipal {C}omponent {A}nalysis ({PCA}) from {CLPP} showed that bacterial catabolic diversity is more influenced than that of fungal communities by anthracene. {C}orrelation between both chemical and biological indicators revealed that the increase in lignocellulolytic enzymes (cellulase, laccase and beta-glucosidase) was significantly correlated to the decrease in phenolic compounds. {I}n addition, aromaticity ratio also decreased in the presence of anthracene suggesting that transformation of the recalcitrant part of organic matter was enhanced. {O}ur results highlight the difference in sensitivity of bacterial and fungal communities to {PAH}s, the later especially active while exposed to high concentrations of pollutant. {T}his suggests that microbial communities inhabiting {P}. halepensis litters in {M}editerranean coastal areas may resist to chronic pollution involving {PAH}.},
