Soil microbial carbon pumps open a new chapter in land carbon sequesbearing.

In the carbon cycle of terrestrial ecosystems, soil microorganisms release carbon into the atmosphere by decomposition and metabolism to convert carbon into some form of storage in the soil.
, there has been a lot of research on microbial decomposition metabolism, but less attention has been payed to the carbon sequesitation of microorganisms through anabolic.
existing research evidence shows that microbial cell residues, the product of microbial assynthesis, are important ingredients in soil stabilization of organic carbon reservoirs.
therefore, understanding and mastering how to regulate microbial source carbon is important for better playing the role of long-term carbon sequest in soils and for establishing sustainable management measures accordingly.
Recently, Liang Chao, a researcher at the Shenyang Institute of Applied Ecology of the Chinese Academy of Sciences, and Julie Jastrow, a professor at the University of California, USA, and Julie Jastrow, a senior scientist at Argonne National Laboratory in the United States, created a new theoretical system for microbial-mediated soil carbon sequestering processes.
the results of the study were published under the Perspective section of the journal Nature Microbiology, under the title The Importance of Anabolism in Microbial Control over Carbon Carbon Storage.
Is based on Liang Chao's core point of view, "soil microbial carbon pump", the theoretical system for the first time defined the "entombing effect", that is, the long-term process of microbial assification led to the iterative accumulation of microbial residues, promoting the formation of a series of microbial residues, including organic matter, and ultimately lead to the stabilization of such compounds in the soil.
This theoretical system, combined with two different carbon metabolism patterns of microorganisms, ex vivo modification and in vivo turnover, systematically describes the dynamic process of carbon derived from plants and microorganisms in soil ecosystems, and clarifies the "carbon pump" enhancement of soil microorganisms through in vivo transmission pathways to enhance the "survival effect" to achieve the contribution of soil carbon sequestosing.
the theoretical system, the researchers pioneered a model of the carbon-nitrogen cycle nested in the "soil microbial carbon pump".
This model is of significant scientific value for regulating carbon from microbial sources, exploring management measures to make soil carbon sequest over a long period of time, and accurately describing and explaining the importance of microbial metabolism in soil carbon sequesay.
in the long run, it is of strategic importance to provide new ideas for optimizing China's farmland, developing low-carbon economy, increasing climate negotiation chips and enhancing international influence.
In addition, the study puts forward-looking and guiding assumptions about some basic ecological problems: microorganisms regulate the chemical composition of soil organic carbon through "in vitro modification" and "in vivo turnover";
the research is mainly supported by the Special Project of Strategic Pilot Science and Technology (Class B) of the Chinese Academy of Sciences, the project on the surface of the National Natural Science Foundation of China, and the national key research and development program.
