Investigating the Effect of Phosphorus Limitation on Growth and Exopolysaccharides Production in Biocrust Cyanobacteria

We present a dataset that contains raw data for different physiological variables (exopolysaccharide production, chlorophyll a, photosynthetic activity) measured for biocrust cyanobacteria under optimal growth and phosphorus limitation treatments in laboratory conditions. These cyanobacteria were collected from biocrusts in the Chihuahuan and Mojave Deserts. The data values were collected for six biocrust cyanobacteria each five days during 20 days. We also provide the data used to create a calibration curve and quantify the concentration of exopolysaccharides. The purpose of this datase is to evaluate the effect of phosphorus limitation on growth, photosynthetic activity and exopolysaccharides production in biocrust cyanobacteria.

本数据集包含实验室条件下，针对生物结皮蓝细菌（biocrust cyanobacteria）在最优生长与磷限制（phosphorus limitation）两种处理条件下测得的多项生理指标原始数据，涵盖胞外多糖（exopolysaccharide）产量、叶绿素a（chlorophyll a）含量与光合活性（photosynthetic activity）。所用蓝细菌采集自奇瓦瓦沙漠与莫哈韦沙漠的生物结皮样本。本数据集针对6株生物结皮蓝细菌，在20天的实验周期内每5天开展一次数据采集。此外，数据集还提供了用于构建校准曲线并定量胞外多糖浓度的相关数据。本数据集旨在评估磷限制对生物结皮蓝细菌的生长、光合活性及胞外多糖产量的影响。
