Description

A kind of Corynebacterium glutamicum of high yield succsinic acid
Technical field
The invention belongs to microbial technology field, be specifically related to a kind of Corynebacterium glutamicum of high yield succsinic acid.
Background technology
Succsinic acid has another name called Succinic Acid, is a kind of common natural organic acids, as the end product of tricarboxylic acid cycle reducing end, extensively is present in human body, plant-animal and the mikrobe, in biological metabolism, occupies critical role.Succsinic acid not only can be used as additive and is applied to industries such as food, medicine, can also be used for synthesizing 1, bulk chemical and PBS Biodegradable materials such as (poly butylene succinates) such as 4-butyleneglycol, THF as C4 hardware and software platform compound simultaneously.
The preparation method of succsinic acid mainly comprises chemical synthesis and biological process.Compare chemical method and be difficult to control, problems such as productive rate is not high, purity is low, catalyzer costliness, it is with low cost that the acid of biological process ambroid has, the higher fixation of C O that has concurrently simultaneously of productive rate 2Characteristics, so biological process prepares the research focus that succsinic acid becomes this year.The main bacteria seed of biological process ambroid acid at present comprises: Anaerobiospirillum succiniciproducens, Actinobacillus succinogenes, Escherichia coli, Mannheimia succiniciproducens etc.Wherein Corynebacterium glutamicum Corynebacteriumglutamicum is rapid because of its growth, culture condition is simple, tolerance is strong, fermentation condition is ripe; While is owing to the disappearance of part enzyme in its anaerobic metabolism approach; Under anaerobic by product is less to make it, becomes the industrial strain of the production succsinic acid of tool potentiality.But wild Corynebacterium glutamicum is in the process of fermentative prodn succsinic acid, and invariably accompany by product L-lactic acid and acetate have influenced the quality of tunning, have increased the load of later separation.
Summary of the invention
Technical problem to be solved by this invention provides the Corynebacterium glutamicum that a plant height produces succsinic acid, does not produce by product L-lactic acid under its anaerobic condition.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is following:
The contriver is through the low energy ion beam implantttion technique, and ATCC13032 carries out mutagenesis to Corynebacterium glutamicum (Corynebacterium glutamicum), obtains a strain Corynebacterium glutamicum through screening, but high yield succsinic acid under its anaerobism does not produce by product lactic acid simultaneously.This bacterial strain; Its classification called after Corynebacterium glutamicum (Corynebacterium glutamicum) SA001, this bacterial strain is preserved in China Committee for Culture Collection of Microorganisms common micro-organisms center (being called for short CGMCC), depositary institution address: No. 3, Yard 1, BeiChen xi Road, Chaoyang District, Beijing City at present; Institute of Microorganism, Academia Sinica; Postcode 100101, the numbering of registering on the books are CGMCC No.3991, and preservation date is on July 2nd, 2010.With this bacterium as producing bacterial strain.
CGMCC No.3991 bacterial strain has property:
1, colonial morphology characteristic:
On nutrient agar, 30 ℃ streak culture is the moderates growth, the lawn wire, and 24h be white, is faint yellow behind the 48h slightly, increases slightly deeply with the prolongation color of incubation time.Surface wettability, smooth, glossy, no stickiness
2, physiology and biochemical characteristic:
A. culture temperature: 28~39 ℃, optimum temperuture is 30 ℃;
B. in pH 5.0~8.5 scopes, grow;
C. pigment production: do not produce pigment;
3, nutritional character:
Corynebacterium glutamicum can grow on synthetic medium, and medium component is clear and definite and cheap.This culture medium carbon source is generally glucose or corn saccharification liquid, and nitrogenous source can be selected Dried Corn Steep Liquor Powder, Carnis Bovis seu Bubali cream, peptone, yeast extract paste, urea and (NH for use 4) 2SO 4Deng; Also comprise the inorganic salts that sylvite, sodium salt, calcium salt, magnesium salts, zinc salt, molysite, manganese salt, phosphoric acid salt, dihydrogen phosphate and hydrochloride etc. are commonly used in the substratum; Nitrogenous source according to different is decided; Need full the interpolation when being only nitrogen source with ammonium sulfate or urea, can be on a small quantity with Dried Corn Steep Liquor Powder, Carnis Bovis seu Bubali cream, peptone, yeast extract paste the time or do not add inorganic salt.
The method of utilizing the Corynebacterium glutamicum of above-mentioned high yield succsinic acid to produce succsinic acid, preserving number is the bacterial strain activation of CGMCCNo.3991 after, at 28~39 ℃ of following aerobic fermentation 12~16h, again at 28~39 ℃ of following anaerobically fermenting 12~36h;
Wherein, the aerobic fermentation substratum is a perfect medium: carbon source 10~40g/L, and nitrogenous source 10~20g/L, inorganic salt 0~3g/L, growth factor 0~0.3mg/L, all the other are water, pH 5.0~7.5;
