由聚球藻属中的蓝细菌的生长和生理学催化的CaCO3沉淀代表了用于封存在用于发电的煤的燃烧期间产生的大气CO2的潜在机制。在微宇宙实验中测试聚球藻属菌株PCC 8806和聚球藻属菌株PCC 8807在暴露于3.4mM的固定钙浓度和0.5mM的溶解无机碳浓度时的钙化能力，聚球藻属菌株PCC 8806在实验期间连续除去钙，产生约18.6mg固体相钙。当测试聚球藻属菌株PCC 8807时，钙去除发生在两天的时间段内，并且仅产生8.9mg固相钙。在这些实验中，蓝藻生理学催化的碱性生长环境的产生似乎是CaCO3沉淀的主要因素。爱思唯尔有限公司出版
Precipitation of CaCO3 catalyzed by the growth and physiology of cyanobacteria in the genus Synechococcus represents a potential mechanism for sequestration of atmospheric CO2 produced during the burning of coal for power generation. Synechococcus sp. strain PCC 8806 and Synechococcus sp. strain PCC 8807 were tested in microcosm experiments for their ability to calcify when exposed to a fixed calcium concentration of 3.4 mM and dissolved inorganic carbon concentrations of 0.5, 1.25 and 2.5 mM. Synechococcus sp. strain PCC 8806 removed calcium continuously over the duration of the experiment producing approximately 18.6 mg of solid phase calcium. Calcium removal occurred over a two-day time period when Synechococcus sp. strain PCC 8807 was tested and only 8.9 mg of solid phase calcium was produced. Creation of an alkaline growth environment catalyzed by the physiology of the cyanobacteria appeared to be the primary factor responsible for CaCO3 precipitation in these experiments.
