In-depth study of the effects of hydrolysis of corn straw on clostridium difficile production

The development of lignocellulose as raw material for liquid biofuels, in line with China's biofuels "not to compete with grain land, do not compete with people for food" policyCorn straw is a large class of china's agricultural production of representative wood cellulose raw materials, wide distribution, large yield, improper treatment is easy to cause environmental pollution, biological conversion of corn straw production butanol is a waste for treasure, a multi-take directionIn the biological fermentation process of corn stalks as raw materials, the pre-treatment of corn stalks causes lignin to degrade and produce a series of different structures, soluble compounds called soluble lignin compoundsSoluble pyetin inhibits the downstream microbial fermentation process and significantly changes the proportion of fermentation products, although scientists have done a lot of research on this inhibition, but the specific mechanism is not clear"text-align: center;"img src""alt""in-depth study of the effects of corn stalks hydrolysis on clostridium difficile production" title""in-depth study of the effects of corn straw hydrolysis on clostridium copsise productionthe microbial resources team of Qingdao Institute of Bioenergy and Process, Chinese Academy of Sciences, carried out an in-depth study on the effects of corn straw hydrolysis on clostridium difficile production, and found that corn straw hydrolysis can inhibit the growth of Clostridium disficiance and sugar utilization, which can be removed by calcium hydroxide detoxification methodsoluble xylin in hydrolysis can produce oxidation pressure, butycol Clostridium bacteria in the process of removing oxidation pressure, will consume reduced force (NADH), which results in a change in the ratio of acetone and butanol in the fermentation final product, resulting in a significant increase in the ratio of acetone in the total solventIn the microbial fermentation process, soluble lignin in hydrolysis can provide electrons to promote the production of hydrogen clostridium cobiteresults provide an important reference for the future study of butyl butanol fermentation based on lignocelluloseThe findings are published online in the journal Applied Environmental MicrobiologyThe work was completed in cooperation with the Institute's Marine Carbon Sink Team, Northeastern University and Sinopec Fushun Research InstituteThe above-mentioned research was supported by the National Natural Science Foundation of China, Jieqing of Shandong Province, the Director's Innovation Fund, and The Sinopec Cooperation Projectspan style"line-height: 1.5;"Message: Zi-Yong Liu Xiu, Qing Yao, Quan Zhang, Zhen Liu, Ze-Jie Wang, Yong-Yu Zhang, Fu-Li Li, (2017), Modulation of the Acetone/Butanol Ratio By Clostridium beijerincki NCIMB 8052.Appl.Environ.Microbiol.doi: 10.1128/AEM.03386-16
