Description
Technical field
The present invention relates to the application of efficient phenol degrading bacterium on phenolic wastewater treatment, belong to environmental protection technical field, also belong to the category of biological reinforcing technology.
Background technology
Phenolic wastewater is one of important pollutent of water body. The method of current domestic and international industrial improvement phenolic wastewater is generally divided into physico-chemical process, chemical method, biochemical process three major types. Show according to long-term trial effect, physico-chemical process, chemical method and biochemical process achieve considerable theoretical result and actual effect in the process of industry phenolic wastewater, as: the aldehydes matter in trade effluent is all had removal effect by stripping method, tower extraction process, absorption method, chemical precipitation method, the ordinary activated sludge method of purification, electrolytic cleaning method etc. But, also there are the problems that can not be ignored, often cost is higher in the input disposed of sewage for physico-chemical process, chemical method, and environment can be caused secondary pollution; For biochemical process, the sewage lower containing phenol concentration only can be processed, thus the industrial phenolic wastewater now still unrealized less investment at present to high density, effective process object.
Be directed to above problem, in conjunction with physics, chemistry and biological treatment containing the relative merits of phenol method for industrial waste water, show that there is wide development space in bioremediation through decades of research. The biological pathway of current own basic understanding microbiological deterioration phenol mainly contains two: 1. aerobic microbiological utilizes phenol hydroxylase to be pyrocatechol by oxidation of phenol, acetyl-CoA, succsinic acid, pyruvic acid etc. can enter tricarboxylic acid cycle, continue to be utilized by microorganism; 2. it is 4-HBA by anaerobion by phenol carboxylation, then through the effect phenylformic acid approach of relevant enzyme, generates acetyl-CoA, finally change into acetic acid, continue to be utilized by microorganism. From this path analysis it may be seen that adopt the phenol microbiological deterioration sewage can carry out under anaerobism or aerobic conditions, therefore, microorganism falls phenol and possesses wider Technological adaptability from principle.
However, set up an efficient microorganism phenolic wastewater treatment technique, still needing to carry out a large amount of previous works, how by the naturalized strain being separated, screening acquired character is excellent, and the microbiobacterial agent developing adaptation production technique further is crucial. And at present, the falling phenol bacterium and can tolerate the concentration of phenol mostly lower (< 1500mg/L) of great majority report; Falling phenol rate and be generally no more than 90%, the research report for high-concentration phenolic wastewater microorganism is then few.
Summary of the invention
The present invention is intended to screen, tame and develop bacterial classification, the bacterium agent of microorganism AgromycessoliPhe-03 and the CorynebacteriumlubricantisPhe-05 of aldehydes matter in relevant efficient degradation industrial sewage, and the process for industry phenolic wastewater, to realize the high-level efficiency processed, low cost, pollutes little effect.
The present invention is achieved through the following technical solutions above-mentioned technological invention object.
(1) chemical environment waste water and neighbouring soil extract microbial bacterial group is utilized, by only phenol being cultivation on the substratum of carbon source, then through obtaining bacterial strain Phe-03 and Phe-05 after screening for several times and domestication in high-concentration industrial phenol-containing wastewater. Through molecular biology identification, Phe-03 is accredited as Agromycessoli bacterial strain; Phe-05 is accredited as Corynebacteriumlubricantis bacterial strain. Two bacterial strains have carried out effective preservation on February 22nd, 2012 in " China typical culture collection center " all, and (China typical culture collection center is called for short CCTCC, also Wuhan University's preservation center is cried, address is: life science institute of Wuhan University of Wuhan City, postcode: 430072). Deposit number is respectively: AgromycessoliPhe-03CCTCCNO:M2012030, CorynebacteriumlubricantisPhe-05CCTCCNO:M2012031; By the content of Artificial Control phenol, for the experimental model of bacterium AgromycessoliPhe-03 and CorynebacteriumlubricantisPhe-05 degradation of phenol ability, efficiency and related detecting method Erecting and improving.
(2) by adopting the domestication of actual industrial phenolic wastewater further, obtain the mixed bacterium agent of suitable sewage environment, and process for pilot scale. Taking common Sewage treatment systems result as blank, compare the effect of bacterium agent on industry phenolic wastewater treatment.
Embodiment
The strain improvement of example 1AgromycessoliPhe-03, CorynebacteriumlubricantisPhe-05 and bacterial preparation process
(1) minimal medium preparation:
By 0.5gKH2PO4��0.5gK2HPO4��0.2gMgSO4��0.2gCaCL2, 0.2gNaCl, micro Fe SO4It is placed in beaker with water to mix, and adjusts between its pH to 7.4-7.6 with NaoH, stir evenly i.e. obtained minimal medium.
(2) preliminary screening of phenol bacterium:
Liquid for 1000ml minimal medium is dispensed into (without the need to sterilizing) in the triangular flask of 5 500ml with 200ml/ bottle, and is numbered: P5��P10��P15��P20��P25, and to P5��P10��P15��P20��P25The middle phenol adding 0.5g/l, 1.0g/l, 1.5g/l, 2.0g/l, 2.5g/l respectively, subsequently to the mud sample adding 5ml in each triangular flask, is positioned over 28 DEG C, cultivates 48h in the shaking table of 210rmp, then respectively from P5��P10��P15��P20��P25Respectively getting a sample is applied on slide, dyes with methylene blue after drying, and observes bacterial growth situation in each triangular flask under the microscope. Observations shows: incrementally observe with phenol concentration, P10��P15Bacterial growth quantity is more, and is evenly distributed; And P25Upper substantially without bacterial growth.
(3) separation and purification of phenolic wastewater bacterium
The inorganic salt nutrient solution prepared and culture dish it is placed at high-pressure sterilizing pot 121 DEG C sterilizing 30min, takes out nutrient solution and plate, respectively to P10��P15��P20��P25Add the phenol solution of 1ml, 1.5ml, 2ml, 2.5ml50%, and mix even with nutrient solution, be down flat ware with 30ml/ ware, take out P10��P15��P20��P25On bacterial strain carry out separation and purification.

(6) selected bacterial strain electron-microscope scanning is observed
In every centrifuge tube, pipette 5ml glutaraldehyde with transfer pipet, and it is numbered phe-03 and phe-05. Choose under spirit lamp conditions for sterilization between ultraviolet is inoculated and get appropriate bacterium tongue and be placed in the centrifuge tube that 2 are equipped with glutaraldehyde, and mixed even, build lid and seal up for safekeeping, after spending the night, pipette appropriate bacterium liquid on slide with transfer pipet, after drying, the process of spray gold, then uses electron microscope observation. Observations shows: two strain bacterium are spherical bacterium. The about 0.5um of thalline diameter, length 0.5-1.0um are not etc.
(7) phe-03, phe-05 identification of strains
Bacterial strain phe-03 and phe-05 passes through total DNA extraction, the general primer amplification of bacterial 16 S rDNA. Amplification object fragment is by utilizing Blast software to carry out similarity searching in GenBank database at GenBank etc. after order-checking, and the 16SrDNA sequence of the typical strain selecting tetraploid rice high than object, then uses CLUSTALX software as ginseng]Carry out multisequencing comparison and calculate examination bacterial strain and join than the sequence similarity between bacterial strain, adopt adjacent method (Neighbor-joining) MAGE4 software building supplying examination bacterium and joining than the phylogenetic tree between bacterium based on 16SrDNA sequence, analytical results shows: phe-03 belongs to Agromycessoli bacterial strain, and phe-05 is that Corynebacteriumlubricantis belongs to bacterial strain.
Two strain bacterium have carried out effective preservation on February 22nd, 2012 in " China typical culture collection center " all. Deposit number is respectively: AgromycessoliPhe-03CCTCCNO:M2012030, CorynebacteriumlubricantisPhe-05CCTCCNO:M2012031.
