Description

Novel microorganism, maltose phosphorylase and trehalose phosphorylase and manufacture method thereof
Technical field
The present invention relates to the manufacture method of novel microorganism, novel enzyme and novel enzyme.Specifically, the series bacillus that the present invention relates to have the throughput of necessary maltose phosphorylase and trehalose phosphorylase with the Production by Enzymes trehalose time belong to novel microorganism, the gene of the aminoacid sequence of the novel maltose phosphorylase that obtains by this microorganism and trehalose phosphorylase, encoding such enzymes and the manufacture method of these enzymes.
Background technology
Trehalose is expected to be widely used in fields such as pharmaceuticals, makeup and food, has carried out many trials in order to carry out industrial production in the past.These technology can roughly be divided into following three classes.The first from trehalose can be accumulated in endobacillary microorganism extract and the method for refining this material (for example, with reference to J.Am.Chem.Soc.72 volume, 2059 pages, nineteen fifty; No. 266584 communique of German Patent; Te Kaiping 3-130084 communique; Te Kaiping 5-91890 communique; Te Kaiping 5-184353 communique and spy open flat 5-292986 communique).This method comprises the cultivation operation, separation circuit of microorganism, extracts the refining crystallization operation of the trehalose of the operation of trehalose, extraction from microorganism, and the manufacturing process of trehalose is quite complicated.And not only the productivity of trehalose is low, and has also produced a large amount of microorganism extraction residues as waste, so can not be called economical efficiency method preferably.
And, also developed produce trehalose fermentation method (for example, open flat 5-211882 communique with reference to the spy), in this method, the microorganism of cultivating brevibacterium sp (Brevibacterium) and Corynebacterium (Corynebacterium) etc. is as the microorganism that produces trehalose outside thalline.Yet in this method, the rate of accumulation of trehalose in substratum is lower, only is about 3% (w/v), at industrial mass production trehalose, needs big volumetrical fermentor tank and the purification apparatus that matches of scale with it, therefore has problems at economic aspect.And, in this method, not only need to carry out sterilization, but also need remove when cultivating numerous and diverse operation by inclusion that uses bacterial strain to produce or medium component etc. in order to obtain the purified trehalose.
On the other hand, also developed enzyme process in order to solve the variety of issue that exists in these fermentation methods.Promptly, orthophosphoric acid salt β-D-glucanotransferase) and derive from the trehalose phosphorylase (α of algae in the presence of phosphoric acid, will derive from the maltose phosphorylase (maltose: of microorganism, α-trehalose: orthophosphoric acid salt β-D-glucanotransferase) act on maltose and produce the method for trehalose (for example, with reference to No. 1513517 communique of Japanese Patent; Agric.Biol.Chem., 49 volumes, 2113 pages, 1985), orthophosphoric acid salt β-D-glucanotransferase) and derive from the trehalose phosphorylase (α of basidiomycetes with the sucrose phosphorylase that in the presence of phosphoric acid, will derive from bacterium (sucrose:, α-trehalose: orthophosphoric acid salt β-D-glucanotransferase) act on the method (for example, with reference to putting down into 6 years Japanese chemurgy meeting conference lecture summary collection 3Ra14) that sucrose obtains trehalose.Can generate trehalose with 60%~70% higher yields from maltose or sucrose according to these methods.And, owing to used high purity sugar after refining,, to compare with additive method so the trehalose that obtains by enzyme reaction also is easy to make with extra care as raw material, this method is considered to industrial useful method.Yet, employed enzyme in these methods, particularly the source of trehalose phosphorylase only limits to euglena (Euglena) or fine and soft (Grifola ffondosa) such algae or the basidiomycetes of dance, in order stably to produce enzyme not only in the economic aspect existing problems, also has any problem at technical elements.And, the dimensional discrepancy of optimal pH separately of the trehalose phosphorylase that obtains, the sucrose phosphorylase that is mated use, maltose phosphorylase is bigger, and also very low to the stability of temperature, can only under 25 ℃~37 ℃ cold condition, carry out the formation reaction of trehalose.The problem of Cun Zaiing is like this, not only when being used two kinds of enzymes, make the control of pH become difficult, and, when using opening reactive tank to carry out enzyme reaction, can cause the pollution of assorted bacterium because temperature of reaction is low, for the side reaction that prevents to bring thus also needs strict hygiene control.And, when being used these known enzymes,, thereby can't use the raw material of high density because these enzymes have the concentration of substrate dependency.Therefore, these methods can not be called as the good method of economical efficiency.
In addition, also delivered the method for making trehalose with the amylolysis thing as substrate.According to this method, to be used for generating malt oligosaccharide based mycose that end has the non-reducing sugar of trehalose structure generates enzyme (Maltooligosyl-Trehalose synthase) and is used for acting on the amylolysis thing from this non-reducing sugar specificity dissociate trehalose resolvase of trehalose, high yield with 80% generates trehalose by starch and (for example, opens flat 7-143876 communique with reference to the spy; European patent application 628630A2 specification sheets; Japan's chemurgy can be given a lecture summary collection, p31 (1995)).Yet, in this method,, being difficult to make described enzyme immobilization and flowing through substrate owing to use starch as substrate, the further manufacturing of reactor etc. is difficult to oversimplify and efficient activity.And the operation of the purging liquid that obtains behind the trehalose crystallization being carried out saccharification more also is difficult to construct.
From the above mentioned, as long as can find to make and make with extra care easy, have higher thermostability and do not have dependent novel maltose phosphorylase of concentration of substrate and trehalose phosphorylase, be that the high yield of raw material is made trehalose simply efficiently with regard to being expected to the maltose that can obtain simply in a large number.
So, first purpose of the present invention is to solve the variety of issue in the described conventional art, providing can the High-efficient Production maltose phosphorylase and the novel microorganism of trehalose phosphorylase, and described maltose phosphorylase and trehalose phosphorylase are the novel enzymes that can satisfy above-mentioned various requirement.Second purpose of the present invention be to provide make and refining easy, have higher thermostability and do not have dependent novel maltose phosphorylase of concentration of substrate and trehalose phosphorylase.And the 3rd purpose of the present invention is to provide the manufacture method of maltose phosphorylase and/or trehalose phosphorylase, in the method, uses described microorganism can obtain above-mentioned two kinds of enzymes simple and effective.

Novel strain of the present invention screens in the following way and obtains.At first, the bottom silt that extracts is suspended in the physiological saline, gets 1 this suspension and spread upon on the nutrient agar with following composition.The Agar Plating that uses contains 2% (w/v) agar, 1% trehalose or maltose, 0.5% polyprotein peptone, 0.5% yeast extract, 0.1% Rhodiaphos DKP and 0.02% magnesium sulfate heptahydrate, and pH is 7.Like this, Agar Plating is carried out aerobic in 37 ℃ cultivate, collect dull and stereotyped each bacterium colony that occurs of going up, each bacterium colony velocity fluctuation with 180rpm in the liquid nutrient medium identical with described nutrient agar composition was cultivated 24 hours~72 hours in 37 ℃.Speed with 12000 * g is carried out centrifugation at 4 ℃ to each nutrient solution, and each nutrient solution is separated into thalline and supernatant liquor.The thalline that so obtains is suspended in a spot of 0.1M phosphoric acid buffer (pH7.0), measures active with the aftermentioned method.So be separated to bacterial strain with described all bacteriology characteristics.
The novel microorganism of finding of the present invention like this, promptly the microorganism of series bacillus genus is the novel bacterium that produces maltose phosphorylase and trehalose phosphorylase.
In order to obtain enzyme of the present invention (being described maltose phosphorylase and trehalose phosphorylase) from novel microorganism of the present invention, for example can this microbial inoculant be cultivated in suitable substratum according to ordinary method, from culture, reclaim then.Consider the growth temperature of microorganism self, culture condition is preferably 25 ℃~42 ℃ temperature range, and preferred aerobic was cultivated 8 hours~70 hours.
For obtaining enzyme of the present invention, the substratum that is used for microorganism culturing is not limited only to material shown below, so long as microorganism can grow and can to produce the nutritional medium of enzyme of the present invention just passable, and synthetic medium or natural medium all can.
As the carbon source of substratum so long as the material that microorganism can utilize is just passable, for example, can use saccharics such as glucose, fructose, seminose, trehalose, sucrose, N.F,USP MANNITOL, sorbyl alcohol, molasses, or organic acids such as citric acid, succsinic acid, preferably use trehalose or maltose and contain trehalose or the saccharic of maltose.If use trehalose or the saccharic that contains this material as carbon source, microorganism then of the present invention preferentially produces trehalose phosphorylase.If use maltose or the saccharic that contains this material as carbon source, microorganism then of the present invention produces maltose phosphorylase and trehalose phosphorylase simultaneously.And, if use trehalose and maltose the two or the saccharic that contains these two kinds of materials as carbon source, then trehalose phosphorylase and maltose phosphorylase can be produced simultaneously, and the generation ratio of trehalose phosphorylase and maltose phosphorylase can also be controlled by the amount of control trehalose and maltose.
All kinds of organic or inorganic nitrogen compounds can be contained in the substratum as nitrogenous source, all kinds of inorganic salt can also be contained.As nitrogenous source, can use the compound that generally is used for microorganism culturing, for example organic nitrogen source such as corn steep liquor, soybean meal or various peptones and sulphur ammonium, ammonium nitrate, phosphorus ammonium, urea etc. are inorganic nitrogen-sourced etc.Urea and organic nitrogen source etc. also can be as carbon sources needless to say.
