Detailed description of the invention
, it should be understood that described embodiment is only for the present invention is described, instead of limit the scope of the invention by any way more specific description the present invention by the following example.
The screening of embodiment 1 enterococcus faecalis CGMCC No.5092
1, primary dcreening operation
The each 5g of sample such as sample thief pig manure, cow dung and chicken manure, are soaked in aseptic 0.85% physiological saline of 20ml, and sample is broken up in concussion, make sample fully and contact with normal saline, 70 DEG C of thermostat water baths leave standstill 3 minutes, get supernatant, centrifugal 10 minutes of 5000rpm, supernatant discarded.Bacterial sediment after centrifugal is added in 10ml simulated gastric fluid, 37 DEG C of standing 2h, then centrifugal, collect after thalline, bacterial sediment is added in the artificial cholate of 10ml, 37 DEG C of standing 4h, collect thalline, and dilution spread is in LB culture medium.37 DEG C of incubators are cultivated after 12-24h, and bacterium colony is carried out to purifies and separates.The bacterium obtaining is preserved, and further sieve again.
The compound method of physiological saline is: 0.85% sodium chloride solution, and for subsequent use after autoclaving.
The compound method of simulated gastric fluid is: 1% pepsin, and 0.85% sodium chloride, with concentrated hydrochloric acid adjust pH to 2.0, for subsequent use after biofilter filtration sterilization.
The compound method of artificial cholate is: in liquid meat soup, add 0.3% pig cholate (analyzing pure), and for subsequent use after autoclaving.
The preparation method of LB solid medium is: peptone 10g, and yeast extract 5g, sodium chloride 10g, agar 1.5%, pH7.0, constant volume is after 1L, for subsequent use after autoclaving.
2, multiple sieve
(1) the LB culture medium temperature of the bacterium that configures, gone out is cooled to 45 DEG C, add Escherichia coli K88, K99 and the staphylococcus aureus (every milliliter of culture medium adds 1 microlitre bacterium liquid) of incubated overnight, concussion mixes, pour aseptic flat board into, after level is solidified, each flat board utilizes four Oxford cups to punch, in every Oxford cup, add 200 μ l bacterium liquid to be measured, build ware lid, carefully move to 37 DEG C of incubators, plate is just being put to leave standstill and is being cultivated.Cultivate after 20h, open ware lid, remove Oxford cup, use kind of calliper antibacterial circle diameter.
Result as shown in Figure 1, can be found out, enterococcus faecalis CGMCC No.5092 Escherichia coli and the staphylococcus aureus being always separated to.
The checking of embodiment 2 enterococcus faecalis resistance
(1) heat-resisting quantity
Carry out centrifugal collection by cultivating the enterococcus faecalis of 12h, insert in physiological saline, carry out resuspended after, sampling coating, meter viable count; Again physiological saline is heated in the water-bath of 70 DEG C after ten minutes, cooling rapidly, then carry out plate count, remaining viable count is 85.3%.
(2) tolerance of simulated gastric fluid
Get the bacterium liquid that 0.5ml cultivates 12h enterococcus faecalis, be dissolved in 4.5ml physiological saline, with colony counting method meter viable count.Get again quantitative above-mentioned bacterium liquid and add in the artificial bile salt culture-medium of 4.5ml, 37 DEG C of standing 2h, the remaining viable count of colony counting method meter, remaining viable count is 92.2%.
(3) tolerance of artificial bile fluid
Get the bacterium liquid that 0.5ml cultivates 12h enterococcus faecalis, be dissolved in 4.5ml physiological saline, with colony counting method meter viable count.Then separately get the above-mentioned bacterium liquid of 0.5ml and add in the artificial bile fluid culture medium of 4.5ml, 37 DEG C of standing 2h, the remaining viable count of the method for plate culture count meter, remaining viable count is 86.2%.
Result: above several experiments show, the resistance of the enterococcus faecalis being separated to from Radix Polygalae Crotalarioidis in the present invention is stronger, can tolerate higher temperature, tolerance simulated gastric fluid, artificial cholate, therefore uses as feed addictive, can ensure that a large amount of thalline is smoothly by the enteron aisle of animal, in enteron aisle, survive, bring into play its prebiotic function.
The prebiotic function of embodiment 3 enterococcus faecalis (CGMCC No.5092)
(1) bacteria resistance function checking
The enteropathogenic E．Coli K88 of incubated overnight, K99 and staphylococcus aureus bacterium liquid are counted with colony counting method.In Escherichia coli K88, the K99 of 3 pipe 5ml and staphylococcus aureus, add 5ml enterococcus faecalis bacterium liquid respectively.Cultivate 4h for 37 DEG C, the method for plate culture count calculates remaining Escherichia coli K88, K99 and the viable count of staphylococcus aureus.The viable count of remaining enteropathogenic E．Coli K88, K99 and staphylococcus aureus is 24.7%, 30.2% and 31.8%.
(2) checking of mould fungus inhibition in corn flour
Get the bacterium liquid 20ml of the enterococcus faecalis of cultivating 12h, evenly mix with 30g corn flour, blank assay is that 20ml sterilized water carries out homogeneous with 30g corn flour and mixes, and then at 3d, 5d, 8d and 10d, the growing state of the corn flour to two bottles of the insides and mould is observed respectively.Show by experiment, after 3 days, do not add in the corn flour of enterococcus faecalis bacterium liquid and have mould filament length to go out, and add the color of corn flour of enterococcus faecalis bacterium liquid still fresh, decompose to some extent but without the appearance of mould bacterial plaque or mould mycelia.After 7 days, mould amount reproduction in blank, and add the corn flour of enterococcus faecalis of the present invention only to have a small amount of mould that (Fig. 2) occurs.
