Problems solved by technology

[0003] However, in the isolation culture method, it takes a long time to separate decomposing microorganisms, and suitable microorganisms are limited to those that can be cultured artificially, and there is a problem of high production cost for further pure culture.
On the other hand, the acclimatization method can grow decomposing microorganisms cheaply and in large quantities, but has the problem that it takes a long time for acclimatization

Embodiment 1

[0074] (Material)

[0075] Concentrates of the components used in the production of the culture medium were prepared by the method shown below. Will (NH 4 ) 2 SO 4 35.4g and Na 2 HPO 4 7.7g was dissolved in 500mL of pure water to make a nitrogen and phosphorus solution with ammoniacal nitrogen of 15000mg / L. KCl 110g and CaCl 2 2H 2 O 50g and CoCl 2 1 mg was dissolved in 1000 mL of pure water to prepare inorganic salt solution 1. NaMoO 4 2H 2 O 5 mg was dissolved in 1000 mL of pure water to prepare inorganic salt solution 2. MgSO 4 ·7H 2 O 85g, FeSO 4 ·7H 2 O8.5g, MnSO 4 ·5H 2 O 2g, ZnSO 4 100mg and CuSO 4 ·5H 2 100 mg of O was dissolved in 1000 mL of pure water to prepare inorganic salt solution 3. The medium in the supply culture was produced as follows: (NH 4 ) 2 SO 4 0.2g and Na 2 HPO 4 1.54 g was dissolved in 1000 mL of pure water, and 1 ml of inorganic salt solution 1, 1 ml of inorganic salt solution 2, and 1 ml of inorganic salt solution 3...

Embodiment 2

[0107] (Material)

[0108] Concentrates of the components used in the production of the culture medium were prepared by the method shown below. MgSO 4 ·7H 2 O100g was dissolved in 1000mL of pure water to make inorganic salt solution A. Na 2 HPO 4 4.152g, NaH 2 PO 4 2.244g and (NH 4 ) 2 SO 4 1.2 g was dissolved in 300 mL of pure water to prepare inorganic salt solution B. (S)-2-(4-chloro Phenyl)-3-methylbutyric acid solution (10g / L). The inorganic particle carrier dispersion was produced by adding 50 g of activated sludge incineration ash to 250 ml of pure water, mixing and suspending. As the activated sludge suspension, the activated sludge collected from the aeration tank of the chemical factory is directly used. The medium that is supplied to the culture is produced as follows: (NH 4 ) 2 SO 4 1.0g, Na 2 HPO 4 1.3g and NaH 2 PO 4 Dissolve 0.9g in 1000mL of pure water, add (S)-2-(4-chlorophenyl)-3-methylbutyric acid solution 4.0mL and 1ml inorganic sa...

Embodiment 3

[0136] The inorganic salt solution used in the production of the culture medium was the same as in Example 1, and the inorganic salt solution 1, the inorganic salt solution 2, and the inorganic salt solution 3 were prepared. (S)-2-(4-Chlorophenyl)-3-methylbutanoic acid solution used the same solution as in Example 2. The influent water was prepared as follows: (S)-2-(4-chlorophenyl)-3-methylbutyric acid solution 1mL, (NH4) 2 SO 4 1g, Na 2 HPO 4 1.298g, NaH 2 PO 4 0.912 g was dissolved in 1000 mL of pure water, and 1 ml of inorganic salt solution 1, 1 ml of inorganic salt solution 2, and 1 ml of inorganic salt solution 3 were added to manufacture. Since the influent water is continuously supplied during the (S)-2-(4-chlorophenyl)-3-methylbutanoic acid removal reaction period, the required amount is appropriately produced. The activated sludge suspension was directly used from the activated sludge collected from the aeration tank of the chemical factory.

Abstract

The method for producing a microbiologic agent according to the present invention comprises: a step for adding, in a medium containing a target compound, an inorganic fine particle carrier and a biomass containing a target compound-degradable microorganism to cause microorganisms contained in the biomass to be supported by the inorganic fine particles, and culturing the target compound-degradablemicroorganism while monitoring the existence ratio thereof with respect to the microorganisms supported by the inorganic fine particle carrier; and a step for obtaining the microbiologic agent by, after the existence ratio of the target compound-degradable microorganism has reached a predetermined value, recovering the inorganic fine particle carrier that supports the target compound-degradable microorganism. The existence ratio of the target compound-degradable microorganism is obtained by a method comprising: a step for obtaining amplification products by amplifying a predetermined region of16S rRNA genes of the microorganisms supported by the inorganic fine particle carrier; and a step for analyzing base sequence data sets of the amplification products, classifying the obtained base sequence data sets into multiple groups on the basis of the homology between respective base sequence data sets, determining each microorganism having a base sequence data set in one of the groups to bea single type, determining the type of the target compound-degradable microorganism on the basis of a representative base sequence data set of each of the groups, and calculating the existence ratioof the target compound-degradable microorganism with respect to all the microorganisms on the basis of the number of the obtained base sequence data sets.

Description

technical field [0001] The present invention relates to a method for producing a microbial preparation and a microbial preparation. Background technique [0002] In wastewater treatment, as a method for removing the target compound from the wastewater, a combustion treatment method, a biological treatment method using a target compound-decomposing microorganism, or the like is used. As a method of obtaining target compound-decomposing microorganisms, a method of enriching and culturing microorganisms decomposing a target compound, identifying, isolating, and purely culturing the decomposing microorganisms (isolation culture method) is known. In addition, in the case of a mixed microbial system such as activated sludge, it is known that the target compound is supplied as a nutrient source at a low concentration, and the activated sludge is accustomed to the target compound by gradually increasing the concentration, thereby improving the decomposition ability. method (domesti...
