Embodiment
Embodiment one: this embodiment fermentation Radix Et Caulis Acanthopanacis Senticosi improves the endogenetic fungus of isofraxidin content in the Radix Et Caulis Acanthopanacis Senticosi; It is Aspergillus ochraceus (Aspergillus ochraceus) AJ14; In China's typical culture collection center preservation; Deposit number is CCTCC No:M 2012042, and the preservation address is a Wuhan City Wuhan University, and preservation date is on February 29th, 2012.
Aspergillus ochraceus in this embodiment (Aspergillus ochraceus) AJ14, it is after cultivating 7d on the PDA solid medium, and colony diameter is 3~5cm, and radial rill is arranged slightly; Tool concentricity, white mycelium, conidium face ochre yellow, quality velvet shape; The a small amount of colourless transudate of tool, the reverse side tawny, conidial head is spherical, and mitogenetic falx stem wall is coarse; The top capsule is spherical, diameter 25~45 μ m, and the surface all can be educated; Conidial fructification is double-deck, and the metulae size is 5~10 μ m * 3~4 μ m, and bottle stalk size is 8~11 μ m * 3~4 μ m; Conidium is spherical, diameter 2.5~3.5 μ m.
Aspergillus ochraceus in this embodiment (Aspergillus ochraceus) AJ14, its growth temperature is 28 ℃, growth pH value is a nature.
The fermentation Radix Et Caulis Acanthopanacis Senticosi improves the endogenetic fungus of isofraxidin content in the Radix Et Caulis Acanthopanacis Senticosi in this embodiment; It is Aspergillus ochraceus (Aspergillus ochraceus) AJ14; This strains separation picks up from area, cap mountain, Heilongjiang Province, 3 years plant ages from the stem of healthy wild Radix Et Caulis Acanthopanacis Senticosi; Robust plant, no disease and pest.Sample is existing in bio-pharmaceuticals specialized laboratory of life science institute of Heilongjiang University; It carries out separation and Culture according to the following steps:
Choose the stem of healthy wild Radix Et Caulis Acanthopanacis Senticosi and rinse the back well with the aseptic filter paper suck dry moisture with tap water; Be cut into the 0.5cm segment, the stem with Radix Et Caulis Acanthopanacis Senticosi in aseptic super clean bench carries out surface sterilization as follows: 75% alcohol-pickled 3~5min-2% Youxiaolin soaks the 15min-aseptic water washing 4 times.With the aseptic operation cutter sample is cut from the centre; Place yam solid separation culture medium and yam liquid separation culture medium respectively; Cultivate in 28 ℃ of constant incubators and the shaking table, treat that its edge and top grow mycelia after, in time picking colony is transferred in the corresponding substratum; Get the sterilized water coating culture plate of last flushing Caulis Et Caulis Acanthopanacis Senticosi or get an amount of this washing fluid and pour in the yam liquid separation culture medium and compare, the experiment material after will sterilizing is in addition rolled on culture plate and is compared in a week, under identical condition, cultivates.
Wherein the every L of yam solid separation culture medium is made up of the yam of 200g, the glucose of 20g, the agar of 20g and the zero(ppm) water of surplus, and the pH value is 7.0~7.2,121 ℃ of following autoclaving 30min;
The every L of yam liquid separation culture medium is made up of the yam of 200g, the glucose of 20g and the zero(ppm) water of surplus, and the pH value is 7.0~7.2,121 ℃ of following autoclaving 30min;
The inclined-plane solid medium is loaded in the test tube for getting 5mL yam solid separation culture medium, behind 121 ℃ of autoclaving 30min, is paved into the inclined-plane cooling, in order to preserving bacterial classification.
Result: from wild Caulis Et Caulis Acanthopanacis Senticosi, isolate endogenetic fungus AJ14; And all not having any bacterium in contrast flat board and the control liquid substratum in the negative control grows; Repeatedly repeat all so, prove that the bacterium of being assigned to is a plant endogenesis epiphyte, rather than the epiphyte on surface.The endogenetic fungus that filters out carries out morphology according to " classification of fungi ", " fungi identification handbook " and " Dendrochium diagram " to be identified; It is very close that the colony characteristics of bacterial strain and spore shape and Aspergillus ochraceus belong to the bacterium characteristic; Colonial morphology is as shown in Figure 1, and the spore microstructure is as shown in Figure 2;
Molecular Identification:
Endogenetic fungus AJ14 fermented liquid suction filtration gets mycelium with 25% ethanol rinsing 2 times; The deionized water rinsing of sterilization 2 times; The centrifugal supernatant that goes adopts Shanghai to give birth to worker UNIQ-10 pillar fungal gene group extraction agent box then and extracts genomic dna, carries out the segmental pcr amplification of purpose (the gel imaging result is as shown in Figure 3) then; Near 500bp (base sequence is seen SEQ ID NO:1), obtain an amplified fragments, prove successfully from the AJ14 bacterial strain, to extract its genomic dna; The PCR product that will contain target stripe all carries out point sample again; Agarose gel electrophoresis with 2% downcuts the purpose band with scalper under uv lamp, reclaims test kit with DNA glue and reclaims; The preparation competent escherichia coli cell; The PCR product with after pMD 18-T carrier is connected, is connected product and joins in the competent cell, carry out bacterium colony PCR checking.The PCR that picking list bacterium colony carries out the intestinal bacteria transformant detects, prove the purpose fragment successfully transforms get in the competent cell after, will clone positive strain and serve extra large living worker's biotechnology Services Co., Ltd and check order.The nucleotides sequence of being measured is listed in the ncbi database Application of B LAST and analyzes and carry out homology relatively; And select the 18S rDNA sequence application software MEGA5.03 constructing system of corresponding kind representative strain to grow according to the ultimate principle of molecular systematics research and set, confirm the classification position of aimed strain.
The ITS sequence that records is committed to the NCBI webpage; Through Blast search and the high sequence of resulting sequence similarity; And through MEGA5.03 software building systematic evolution tree (as shown in Figure 4); The similarity that the ITS sequence of AJ14 bacterial strain and Aspergillus ochraceus belong to bacteria strain has all reached more than 98%, and combining form is learned observations, confirms that the AJ14 bacterial strain is Aspergillus ochraceus (Aspergillus ochraceus).
