Abstract
It is still an important aspect of global climate research to explore a low-cost method that can effectively reduce the increase of CO2 concentration in the global atmosphere. Oxalotrophic bacterial communities exist in agricultural or forest soil with ubiquitous oxalate as the only carbon and energy source. When soil oxalate is oxidized and degraded, carbonate is formed along with it. This process is called the oxalate carbonate pathway (OCP), which can increase soil inorganic carbon sink and soil organic matter content. This soil carbon sink is a natural CO2 trapping system and an important alternative if it is properly managed for artificial sequestration/storage. As the main driver of OCP, the oxalate degrading bacteria are affected by many factors during the oxalate conversion process. Understanding this process and the synergy of oxalogenic plants, saprophytic decomposers, and oxalotrophic bacteria in agricultural or forest soil is critical to exploiting this natural carbon capture process. This article aims to provide a broader perspective of OCP in CO2 sequestration, biomineralization, and elemental cycling.
Highlights
Carbon dioxide (CO2) assimilation by photosynthesis is ubiquitous, whereas mineralization of CO2 into inorganic carbon compounds is majorly underrated, which usually involves the synergy of oxalogenic plants, saprophytic decomposers, and oxalotrophic bacteria
Oxalate Carbonate Pathway for Sustainability are presented as oxalate carbonate pathway (OCP) is extremely variable)
We intend to provide a perspective for the future use and deployment of CaOx generating plants and oxalotrophic bacteria across different scenarios, offering a realistic approach to impacting the natural environment with an outcome including, but not limited to, CO2 emissions mitigation, and soil organic carbon (OC) restoration
Summary
Carbon dioxide (CO2) assimilation by photosynthesis is ubiquitous, whereas mineralization of CO2 into inorganic carbon compounds is majorly underrated, which usually involves the synergy of oxalogenic plants, saprophytic decomposers, and oxalotrophic bacteria. The OCP plays an important role in reducing atmospheric CO2 and increasing soil carbon content (Braissant et al, 2004; Cailleau et al, 2005; Rowley et al, 2017a; Durand et al, 2018), but requires numerous, autonomous, biotic, and abiotic components rendering OCP a unique and highly complex phenomenon with limited comprehensive studies (Martin et al, 2012; Cailleau et al, 2014; Rowley et al, 2017b) Despite such tremendous potential of OCP, current research is limited to the mechanism, participating and influencing agents with negligible quantitative characteristics We intend to provide a perspective for the future use and deployment of CaOx generating plants and oxalotrophic bacteria across different scenarios, offering a realistic approach to impacting the natural environment with an outcome including, but not limited to, CO2 emissions mitigation, and soil organic carbon (OC) restoration
