Abstract: Consolidated bioprocessing (CBP) is a biological process that combines cellulose production, cellulose hydrolysis saccharification, pentose and hexose fermentation into one step. CBP is influenced by the single microorganism or microbiome. This article focuses on the development course of fungi in cellulosic ethanol production using CBP. Meanwhile, it reviews the development process of cellulosic ethanol industrialization, and then introduces the function mechanism of cellulosic ethanol produced by CBP. In addition, this paper systematically summarizes the main types of the original fungi in CBP as reported in the literatures as well as their advantages and disadvantages. Moreover, it reviews the development strategies of fungi in CBP, including the engineering strategies and the co-culture strategies. Engineering strategies has been emphatically stated from the prespectives of the technological routes and the research progress. The article also points out that the combination of advanced biotechnology and computer simulation system based on metabolic analysis data to develop target microorganisms in CBP, the design of new and efficient bioreactors and the integration of CBP technology with the existing biotechnology, is the key for the future application of CBP technology in the cellulosic ethanol industry.
