Influence of CO2 on Water Chemistry and Bacterial Community Structure and Diversity: An Experimental Study in the Laboratory

As the second largest carbon pool, soil has a high CO2 content, and it has an important impact on water–rock interactions and the bacterial community structure and diversity in soils. In this paper, three sets of laboratory simulation experiments under six levels of partial pressure CO2 (pCO2) conditions were used to analyze and study the CO2–water–rock interactions and the bacterial community structure and diversity changes in soil under normal...
