Embodiment 1

[0036] Embodiment 1, the screening and effect verification of butanol and succinic acid produced by fermentation of the present invention

[0037] Fermentative production of butanol and succinic acid of the present invention are respectively used to produce CO 2 Microbial fermentation produces butanol, using available CO 2 Microbial fermentation produces succinic acid; the schematic diagram of its production equipment is shown in figure 1 as shown, figure 1 Among them, 1 is a butanol fermentation tank; 2 is a succinic acid fermentation tank; 3 is a valve; 4 is a gas filter; the tail gas of the butanol fermentation tank 1 passes through the valve 3 and the gas filter 4 into the succinic acid fermentation tank 2 .

[0038] The following examples carry out butanol fermentation with Clostridium acetobutylicum (Clostridium acetobutylicum) SB-1 (China General Microorganism Culture Collection and Management Center, CGMCC No.2287), and carry out with succinic acid Actinobacillus (A...

Abstract

The invention discloses a method for producing butyl alcohol and succinic acid through fermentation. The method which is the method for producing the butyl alcohol and the succinic acid produces the butyl alcohol and the succinic acid simultaneously through fermenting microbe in different systems and gas which is produced in producing the butyl alcohol through the fermentation is inputted in a system for producing the succinic acid through the fermentation. The method connects a butyl alcohol fermentation system and a succinic acid fermentation system in series, CO2 and H2 which are produced through fermenting the butyl alcohol are utilized to promote succinic acid synthesis, which not only realizes the comprehensive use of the CO2, reduces the discharge of greenhouse gas, but also reduces the using amount of carbonate in the succinic acid producing process. The method does not need reforming complex devices and only needs adding a filtrating and removing bacteria device and then connecting with an air intake duct of a succinic acid fermentor. Experiments show that the method of the invention can keep or even increase the synthesis concentration of the succinic acid under the condition that the carbonate is not additionally added and simultaneously butyl alcohol synthesis is not affected.

Description

technical field [0001] The invention relates to a method for producing butanol and succinic acid by fermentation. Background technique [0002] After a long evolution process of 4 billion years, today's accurate, efficient, scientific and stable ecosystem has been formed on the earth. However, the rapid development of the industrial system in just 150 years has not only caused the world to face serious resource and energy crises, but also caused many serious social problems such as global warming. 2 The main contributor to China's emissions has already ranked second in the world and will continue to increase. [0003] CO 2 It is not only the gas that has the greatest impact on the "greenhouse effect" of the atmosphere, but also the most abundant carbon resource on the earth. People can pass CO 2 Emission reduction and carbon sequestration, combined with improving energy production and use efficiency and increasing the production and utilization of low-carbon or non-carbo...
