Dataset for Salinity-driven microbial carbonate precipitation

This dataset contains the numerical data supporting all figures presented in the main text and Supplementary Information of the manuscript. The dataset includes time-series measurements of bacterial activity, urease activity, and Ca²⁺ concentrations under different salinity conditions (Fig. 2), quantitative crystal growth data obtained from microfluidic crystal-tracking experiments (Figs. 3 and 4), crystal size evolution and growth rate analyses (Fig. 5), Ca²⁺ removal dynamics during alternating low- and high-salinity treatments (Fig. 6), and particle size distributions and mineralogical characterization data for biominerals formed under different salinity conditions (Fig. 7). Supplementary datasets include additional time-course profiles, viability analyses, and supporting microfluidic and mineralogical data corresponding to SI-Figs. S3, S4, S6, and S7. All datasets are provided in open, machine-readable formats and can be used to reproduce the figures and verify the key trends and conclusions reported in this study.本数据集包含支撑该研究手稿正文与补充信息中所有图表的数值型数据。数据集涵盖不同盐度条件下的细菌活性、脲酶活性及钙离子（Ca²⁺）浓度的时序测量数据（对应图2）；从微流控晶体追踪实验中获取的定量晶体生长数据（对应图3与图4）；晶体尺寸演化与生长速率分析数据（对应图5）；交替高低盐度处理过程中的钙离子去除动力学数据（对应图6）；以及不同盐度条件下形成的生物矿物的粒径分布与矿物学表征数据（对应图7）。 补充数据集包含额外的时程曲线、存活率分析数据，以及对应补充图S3、S4、S6和S7的微流控与矿物学支撑数据。所有数据集均采用开放且可机器读取的格式提供，可用于复现本研究中的图表，并验证本研究报道的关键趋势与结论。
