Description
Technical field
The invention belongs to microbial fermentation technology field, be specifically related to a kind of method of utilizing sugar cane juice fermentation production of succinic acid, relate to Actinobacillus succinogenes (Actinobacillus succinogenes) simultaneously and prepare the application of the method for succinic acid as raw material take sugar cane juice.
Background technology
Succinic acid, claims again succsinic acid (succsinic acid), is a kind of common natural organic acids, is extensively present in animal and plant and microbe, is one of biology intermediate product of carrying out TCA circulation.Succinic acid is a kind of important organic synthesis intermediate, by U.S. FDA, is regarded as GRAS, it is generally acknowledged safety, is mainly used in the fields such as food, medicine, biodegradable plastic, tensio-active agent, washing composition and green solvent.In addition, succinic acid can also be as aspects such as animal feedstuff additive and plant growth stimulators.
At present, it is mainly the method for utilizing chemosynthesis that succinic acid is produced, and produces succsinic acid, mainly by methods such as paraffin oxidation style, light oil oxidation style, butane oxidation method, succinonitrile hydrolysis method, shortenings from butane by Maleic anhydride.Chemically produce succinic acid, need to consume a large amount of non-renewable petrochemical materials, production cost is high, and environmental pollution is serious, thereby has limited the widespread use of succsinic acid.Therefore, people start target diversion to produce succsinic acid by biological fermentation process.Compare with traditional chemical synthesis, fermentation method has the advantages such as cost is low, environmental benefit is good, and has opened up the new way of greenhouse gases Carbon Dioxide Application.At present, the succsinic acid obtaining by fermentative Production, its price is approximately 0.55～1.1 ﹩/kg.In addition, according to Bio-amber company, claim, succsinic acid has the market of 2,500,000,000 Euros, and biological process produces succsinic acid and can compete mutually with the method for petrochemical industry, and plans to utilize plant to carry out industrial production of succinic acid as raw material before 2011.
Succinic acid is the important intermediate of many strictly anaerobic bacteriums and facultative anaerobe metabolism.It has been found that at present multiple-microorganism can produce succsinic acid by fermentation, wherein research mainly concentrates on intestinal bacteria (E.coli), succsinic acid bacterium (Mannheimia succiniciproducens), Anaerobiospirillum succinoproducens (Anaerobiospirillum succiniciproducens) and Actinobacillus succinogenes (Actinobacillus succinogenes) are produced in mannheim.In addition, some milk-acid bacterias, propionic acid produce bacterium and fungi etc. and also can produce a small amount of succinic acid.In numerous product succsinic acid microorganisms, rumen microorganism Actinobacillus succinogenes can utilize various saccharides to ferment, and the concentration that can tolerate glucose and succsinic acid is respectively up to 158g/L and 104g/L; Meanwhile, this bacterium, with advantages such as its high yield, height endurabilities, becomes one of Screening of Succinic-producing Strain most with prospects.
At present, the substratum of relevant fermentation method succinic acid-producing carbon source used, except glucose, is mainly grain raw material, as U.S. Argonne laboratory carried out the research of Maize Production succinic acid (
www.ipd.anl.gov/biotech/index.html, 2002), Japanese aginomoto and Mitsubishi Chemical Ind jointly combine carry out take W-Gum be fermenting raw materials produce the research of succinic acid (
http:// www.bio168.com, 2005).
But flourish due to the biological industry of grain raw material in recent years, there is shortage in grain, price increase trend is obvious, in addition depending on grain unduly also can affect national grain security, so use cheap non-grain raw material to carry out succinic acid fermentation, is the key that reduces succinic acid production cost and industrialization.
Relevant non-grain raw material is produced succinic acid research some reports both at home and abroad, Korea S Lee PC has reported with Manheimia succiniciprducens MBEL55E fermented whey raw material succinic acid-producing, Japan scientist Inui etc. utilizes cellulosic hydrolysate to produce succinic acid, the Sun Zhi of Southern Yangtze University is great waits people to carry out the research of fermentation succinic acid with raw materials such as molasses, bajiao banana taros, the logical seminar of the Jiang Min of Nanjing University of Technology and the Jiang Shao of HeFei University of Technology reports cellulosic material succinic acid-producing, and Guangxi Academy Of Sciences Huang ripple seminar take cassava and is studied as raw material succinic acid-producing.At present, take sugar cane juice have not been reported as raw material production succinic acid research.
Sugarcane is the general name of saccharum (Saccharum), belongs to C4 plant, and it has very high photosynthetic rate, is that traditional non-grain crop, sugary height, output are high.Sugar cane juice is the juice producing after cane milling, the general 15-20% of sugar degree, contains the nutritive substances such as aspartic acid, aspartic acid, L-Ala, citric acid, vitamin A, vitamins C, nicotinic acid, riboflavin and iron, calcium, phosphorus, manganese, zinc in addition.
