Picocyanobacteria (Prochlorococcus or Synechococcus) and picoeukaryote (Micromonas and Ostreococcus) cell concentrations and hydrogen peroxide (HOOH) concentrations during batch culture at the University of Tennessee, Knoxville

These data include picocyanobacteria (Prochlorococcus or Synechococcus) and picoeukaryote (Micromonas and Ostreococcus) cell concentrations and hydrogen peroxide (HOOH) concentrations during batch culture. Cultures were either amended with ~400 nanomolar (nM) HOOH on day 0 or left unamended, and cell counts and HOOH concentrations were quantified over several days of incubation. The ability of Synechococcus and picoeukaryotes to protect Prochlorococcus from HOOH was addressed and compared to the protection conferred by the 'helper' heterotroph Alteromonas macleodii EZ55.本数据集涵盖分批培养（batch culture）过程中，微微型蓝细菌（picocyanobacteria，包含原绿球藻属*Prochlorococcus*与聚球藻属*Synechococcus*）、微微型真核生物（picoeukaryote，包含微单胞藻属*Micromonas*和奥斯塔藻属*Ostreococcus*）的细胞浓度，以及过氧化氢（hydrogen peroxide，HOOH）的浓度数据。实验设置两组培养体系：一组于第0天投加约400纳摩尔（nanomolar，nM）的过氧化氢，另一组不做投加处理作为对照；在多日孵育培养期间，对细胞计数与过氧化氢浓度进行定量测定。本研究同时探究了聚球藻与微微型真核生物对原绿球藻抵御过氧化氢的保护能力，并将其与“辅助”异养生物（heterotroph）麦克氏交替单胞菌EZ55（Alteromonas macleodii EZ55）所提供的保护效果进行了对比。
