  abstract = {{T}he effects of grazing pressure and inorganic nutrient availability on the direct carbon transfer from freshly produced phytoplankton exudates to heterotrophic bacteria biomass production were studied in {M}editerranean coastal waters. {T}he short-term incorporation of {C}-13 (({HCO}3)-{C}-13) in phytoplankton and bacterial lipid biomarkers was measured as well as the total bacterial carbon production ({BP}), viral lysis and the microbial community structure under three experimental conditions: (1) {H}igh inorganic {N}utrient and {H}igh {G}razing ({HN}+{HG}), (2) {H}igh inorganic {N}utrient and {L}ow {G}razing ({HN}+{LG}) and (3) under natural in situ conditions with {L}ow inorganic {N}utrient and {H}igh {G}razing ({LN}+{HG}) during spring. {U}nder phytoplankton bloom conditions ({HN}+{LG}), the bacterial use of freshly produced phytoplankton exudates as a source of carbon, estimated from {C}-13 enrichment of bacterial lipids, contributed more than half of the total bacterial production. {H}owever, under conditions of high grazing pressure on phytoplankton with or without the addition of inorganic nutrients ({HN}+{HG} and {LN}+{HG}), the {C}-13 enrichment of bacterial lipids was low compared with the high total bacterial production. {BP} therefore seems to depend mainly on freshly produced phytoplankton exudates during the early phase of phytoplankton bloom period. {H}owever, {BP} seems mainly relying on recycled carbon from viral lysis and predators under high grazing pressure.},
