Abstract
Microbial fixation of carbon dioxide (CO2), represented by photosynthesis, is an important link of the global carbon cycle. It provides the majority of organic chemicals and energy for human consumption. With the great development and application of fossil resources in recent years, more and more CO2 has been released into the atmosphere, and the greenhouse effect is looming. Therefore,

more efficient carbon fixation processes are urgently needed. In view of this, the microbial conversion of exhaust CO2 into valuable fuels and chemicals based on an efficient CO2 fixation pathway is very promising. With the rapid development of systems biology, more and more insights into the natural carbon fixation processes have become available. Many attempts have been made to enhance the biological fixation of CO2, by engineering the key carbon fixation enzymes, introducing natural carbon fixation pathways into heterotrophs, redesigning novel carbon fixation pathways, and even developing novel energy supply patterns. In this review, we summarize the great achievements made in recent years, and discuss the main challenges as well as future perspectives on the biological fixation of CO2. It is the key step of the global carbon cycle to convert inorganic carbon into organic chemicals. Organic chemicals and energy currently consumed by humans in the world are mainly derived from organic carbon fixed from CO2. Energy and the environment are two major issues that are closely related to human life. The release of tremendous and increasing amounts of CO2 into the atmosphere has attracted worldwide attention due to the greenhouse effect. Recycling the abundant waste CO2 directly into fuels or chemicals is a potential approach to provide a sustainable energy supply and to reducing the greenhouse effect. Carbon atoms in common fuels and chemicals are in lower states, while those in CO2 molecules are in the highest oxidation state. Significant energy input is thus required to convert inorganic CO2 to organic compounds. Autotrophs fix CO2 through evolved carbon fixation pathways, with light or inorganic chemical as the e
