摘要：
The continuous growth of the global population has greatly increased the demand for meat, eggs and dairy products and other living products, as well as unprecedented challenges to the supply of traditional animal feed. Microorganisms are capable of utilizing carbon dioxide (CO2), methane (CH4) and other raw materials to synthesize single cell protein (SCP) with high protein content for feed or food processing. Bioconversion of CO2 and CH4 to produce SCP can not only expand the ways of protein production and alleviate the market demand, but also reduce the SCP cost and promote energy saving and emission reduction. In this review, the metabolic pathways of aerobic methanotroph and microalgae, bioconversion process, and bioreactor design are discussed based on the current research progress and literature of SCP synthesis and production. Finally, the economic feasibility of SCP production from greenhouse gases is preliminarily estimated and compared in order to evaluate the potential of commercial application. © 2021, Editorial Board of CIESC Journal.
