Polyphosphate in bacteria Alteromonas sp., Vibrio sp., and Photobacterium ganghwense under phosphorus and organic carbon limitations

Three marine heterotrophic bacteria species were cultured under phosphorus (P) and organic carbon limitations and monitored for their dynamics of growth (optical density and viable cell counts), cellular polyphosphate (polyP), total biomass P (TPP), activities of alkaline phosphatase, and the relative expression levels of polyP metabolic genes including ppk1, ppk2, and ppx. The medium concentrations of phosphate, glucose, and dissolved organic carbon (DOC) were also measured.本数据集选取三种海洋异养细菌（marine heterotrophic bacteria），分别在磷（P）限制与有机碳限制两种培养条件下对其进行培养，同步监测其生长动态（包括光密度（optical density）与活菌计数（viable cell counts））、细胞内多聚磷酸盐（polyphosphate，polyP）水平、总生物量磷（total biomass P，TPP）、碱性磷酸酶活性，以及ppk1、ppk2、ppx等多聚磷酸盐代谢基因的相对表达水平；同时还测定了培养基内磷酸盐、葡萄糖与溶解有机碳（dissolved organic carbon，DOC）的浓度。
