  abstract = {{A}lexandrium tamarense ({M}. {L}ebour) {B}alech strains isolated in spring 2007 from a single bloom in {T}hau lagoon have been grown in nonaxenic artificial media. {F}or three strains showing large oscillations in biomass (crashes followed by recoveries) on a scale of several days, a significant relationship was observed between changes in cell densities (as in vivo fluorescence) and changes in nitrate concentrations. {I}ncreases in cell densities were accompanied by decreases in nitrate, while decreases in cell densities corresponded to increases in nitrate, presumably due to nitrification. {N}et increases in nitrate could reach up to 15 mu mol {N} . {L}-1 . d(-1) indicating a very active nitrifying archaeal/bacterial population. {H}owever, following population crashes, algal cells can recover and attain biomass levels similar to those reached during the first growth phase. {T}his finding indicates that those archaea/bacteria do not compete for nutrients or do not hamper algal growth under those conditions. {I}n contrast to diatoms, dinoflagellates such as {A}. tamarense do not excrete/exude dissolved organic matter, thus preventing excessive bacterial growth. {T}his mechanism could help explain the recovery of this species in the presence of bacteria.},
