This bacterial strain was stored in China Committee for Culture Collection of Microorganisms's common micro-organisms on September 21st, 2018
The heart, address: Yard 1, BeiChen xi Road, Chaoyang District, Beijing City, Institute of Microorganism, Academia Sinica, culture presevation number is CGMCC
NO.16525。
Embodiment 2: the nematicidal effect of molten albumen bacillus (Bacillus proteolyticus) Bp-196 bacterial strain
1. prepared by the fermentation liquid of molten albumen bacillus (Bacillus proteolyticus) Bp-196 bacterial strain
By molten albumen bacillus Bp-196 strain inoculated into fermentation medium, at 30 DEG C, with the revolving speed of 220rpm
Culture 3 days, to obtain the fermentation liquid of molten albumen bacillus Bp-196 bacterial strain.Wherein, fermentation medium includes: 5g/L yeast
Powder, 10g/L peptone, 10g/L sodium chloride are settled to 1L using distilled water.
2. nematode is used in preparation test
Root-knot nematode picks up from Vegetable & Flower Inst., Chinese Academy of Agriculture Science greenhouse.By the root of the capsicum of root-knot nematode morbidity
System takes out, and is gently rinsed with water, carefully removes pieces of an egg from root system surface, be placed in 1% sodium hypochlorite and sterilize 3min, then use nothing
Bacterium water rinses 3 times, is placed in the culture dish containing a small amount of sterile water, cultivates in 25 DEG C of insulating boxs, and -48h collects hatching for 24 hours
Root-knot nematode second instar larvae is used for experimental study with sterile aqueous suspension.
3. test method
Take molten albumen bacillus Bp-196 bacterial strain fermentation liquid and its 10 times, 100 times of dilutions handle above-mentioned respectively
Tie lines worm second instar larvae measures molten albumen bacillus Bp-196 fermentation liquid to the kill effect of root-knot nematode.
12 24 sterile porocyte culture plates are taken, 12 tissue culture plates are divided into four groups, every group of test is repeated 3 times,
And fermentation liquid, 10 times of fermentation liquids of dilution, dilution 100 times of fermentation liquids and sterile are added into hole respectively in every group of tissue culture plate
Each 1mL of water, wherein zymotic fluid group will be added, 10 times of zymotic fluid groups of dilution are added and 100 times of zymotic fluid groups of dilution are added as examination
Group is tested, sterile water group will be added as a control group, 100 μ L nematode suspension are then added into four groups of tissue culture plates respectively
(about 100 nematodes), is placed on the death condition cultivated observe root-knot nematode for 24 hours at room temperature, and calculate corrected mortality, as
Nematicidal effect.
Corrected mortality (%)=(test group root-knot nematode average mortality-control group root-knot nematode average mortality)/
(1- control group root-knot nematode average mortality) * 100%
Table 1 is the examination of the fermentation liquid killing root-knot nematode second instar larvae of the molten albumen bacillus Bp-196 bacterial strain of various concentration
Test result.
The test of the fermentation liquid killing root-knot nematode second instar larvae of the molten albumen bacillus Bp-196 bacterial strain of 1 various concentration of table
As a result
| The death rate (%) | Zymotic fluid group | Dilute 10 times of zymotic fluid groups | Dilute 100 times of zymotic fluid groups | Sterile water group |
| Repeat test 1 | 100 | 94.5 | 10.2 | 1.2 |
| Repeat test 2 | 100 | 90.7 | 9.8 | 1.1 |
| Repeat test 3 | 100 | 92.2 | 9.6 | 1.1 |
| Average mortality | 100 | 92.5 | 9.9 | 1.1 |
| Corrected mortality | 100 | 92.5 | 9.9 | — |
It can be seen that the molten albumen bacillus Bp-196 fermentation liquid of different extension rates to nematode by above-mentioned test
Function and effect are different.When not being diluted to fermentation liquid, the insecticidal effect to root-knot nematode is 100%；When to fermentation liquid
When diluting 10 times, 92.5% is still reached to the insecticidal effect of root-knot nematode；And when diluting 100 times to fermentation liquid, it is right
The insecticidal effect of root-knot nematode is very low, and only 9.9%, the difference very little with control group illustrates molten albumen bacillus Bp-196
The fermentation liquid of bacterial strain has good prevention and treatment root-knot nematode effect in higher concentrations.
Embodiment 3: the nematicidal effect of molten albumen bacillus (Bacillus proteolyticus) Bp-196 bacterial strain
1. prepared by the fermentation liquid of molten albumen bacillus (Bacillus proteolyticus) Bp-196 bacterial strain
By molten albumen bacillus Bp-196 strain inoculated into fermentation medium, at 30 DEG C, with the revolving speed of 220rpm
Culture 3 days, to obtain the fermentation liquid of molten albumen bacillus Bp-196 bacterial strain.Wherein, fermentation medium includes: 5g/L yeast
Powder, 10g/L peptone, 10g/L sodium chloride are settled to 1L using distilled water.
2. nematode is used in preparation test
Root-knot nematode picks up from Vegetable & Flower Inst., Chinese Academy of Agriculture Science greenhouse.By the root of the capsicum of root-knot nematode morbidity
System takes out, and is gently rinsed with water, carefully removes pieces of an egg from root system surface, be placed in 1% sodium hypochlorite and sterilize 3min, then use nothing
Bacterium water rinses 3 times, is placed in the culture dish containing a small amount of sterile water, cultivates in 25 DEG C of insulating boxs, and -48h collects hatching for 24 hours
Root-knot nematode second instar larvae is used for experimental study with sterile aqueous suspension.
3. test method
It taking 180 plants of cucumber seedlings to be tested, 180 plants of cucumber seedlings is divided into two groups, every group of test is repeated 3 times, and
The fermentation liquid and each 15mL of sterile water of molten albumen bacillus Bp-196 bacterial strain are uniformly poured in every group of cucumber seedling soil respectively,
Wherein, using the cucumber seedling group for pouring molten albumen bacillus Bp-196 fermentation liquid as test group, the Huang of sterile water will be poured
Melon seedling group is as a control group.After 1 day, to the cucumber seedling of test group and control group be inoculated with root-knot nematode second instar larvae, every plant
Inoculation 500, at room temperature normal culture, and the root knot quantity after 5 weeks on the cucumber seedling of detection test group and control group,
Preventive effect of the fermentation liquid to root-knot nematode of molten albumen bacillus Bp-196 bacterial strain is calculated with this.
Control efficiency calculation formula:
Control efficiency (%)=(1- test group be averaged root knot quantity/control group be averaged root knot quantity) * 100%
Table 2 is that the fermentation liquid of molten albumen bacillus Bp-196 bacterial strain prevents the test result of root-knot nematode.
The test result of the fermentation liquid prevention root-knot nematode of the molten albumen bacillus Bp-196 bacterial strain of table 2
| Root knot number | Zymotic fluid group | Sterile water group |
| Repeat test 1 | 18.9 | 135.7 |
| Repeat test 2 | 17.1 | 124.5 |
| Repeat test 3 | 16.2 | 127.1 |
| Average root knot number | 17.4 | 129.1 |
It can be calculated according to control efficiency calculation formula, the fermentation liquid of molten albumen bacillus Bp-196 bacterial strain is to root
The control efficiency of tie lines worm has reached 86.5%.
It can be seen that the cucumber plant after the fermentation liquor treatment of molten albumen bacillus Bp-196 bacterial strain by above-mentioned test
On root knot quantity significantly reduce.In control group, 129.1/plant of root knot quantity average out to of cucumber, and through molten albumen bud
17.4/plant of root knot quantity average out in the cucumber of the fermentation liquor treatment of spore bacillus Bp-196 bacterial strain.It can be obtained by calculating
It arrives, the fermentation liquid of molten albumen bacillus Bp-196 bacterial strain has reached 86.5% to the control efficiency of root-knot nematode, illustrates molten egg
White bacillus Bp-196 bacterial strain can be with effectively preventing cucumber root-knot nematode.Have in agricultural production prevention and treatment root knot nematode disease
Important value.
