| Abstract: | Cyanobacteria， which have a fossil record of 3.5 billion years， have continued to flourish up to the present day. Cyanobacterial metabolic processes have influenced the ecological evolution of the earth. Scientific questions related to cyanobacteria， such as the “Precambrian enigma”， have challenged researchers. The extracellular polymeric substances of cyanobacteria play a crucial role in cyanobacterial calcification. The main characteristics of cyanobacteria and extracellular polymeric substances are systematically introduced in this study， following an analysis of several reports in the research literature from China and elsewhere. Reports of previous studies on the calcification process related to photosynthesis and the degradation process of cyanobacteria were reviewed and summarized. The role of extracellular polymeric substances of cyanobacteria in its calcification process was analyzed. The geological significance and future research prospects are addressed to provide references and clarifications regarding scientific questions about the calcification of cyanobacteria and microbial mats. |
