Liquid has inhibiting effect to the growth of aspergillus flavus；Pediococcus acidilactici, lactobacillus plantarum, the supernatant of bacillus coagulans mixed culture are dense
The bacteriostatic diameter of contracting liquid is 15.173 ± 0.032mm.
Experimental result data:
2 results
The growth curve of 2.1 strains
In Fig. 1, it can be seen that from the growth curve chart of lactobacillus plantarum and initially enter logarithm after the lag phase of 2h or so
Growth period reaches maximum OD in 22h600Nm value 3.482 ± 0.003；Starting pH declines rapidly after 2h for 5.40, in 22h
Reach minimum 4.16 ± 0.021；It can be seen that from the change curve of fermentation liquid glucose residual quantity with every 2h close to 1.0g/L
Downward trend decline, RG value is minimum when 22h, be 7.58 ± 0.144, have dropped 8.25g/L compared with starting fermentation liquid RG value,
OD600nm value, pH value and RG value three's change curve are consistent.
From the growth curve chart (Fig. 2) of Pediococcus acidilactici as can be seen that initially entering logarithm after the lag phase of 2h or so
Growth period reaches maximum OD in 20h600Nm value 4.686 ± 0.006；Its pH value drops to from starting 5.37 by 22h minimum
Value 4.21；Unlike lactobacillus plantarum, the RG value of Pediococcus acidilactici fermentation liquid is lower, for 24 hours when be 4.42 ± 0.144 (P
<0.05)；Compared with lactobacillus plantarum, the OD of Pediococcus acidilactici600Nm value is higher (P < 0.05).
Unlike both the above bacterial strain, as shown in figure 3, bacillus coagulans just initially enter logarithm life in 6h or so
For a long time, and logarithmic phase is shorter, its OD of 20h or so600Nm value reaches maximum value 4.094 ± 0.010, and value is between plant cream bar
Between bacterium and Pediococcus acidilactici (P < 0.01)；Its pH value reaches minimum 4.26 ± 0.025 in 12h, from 12h~for 24 hours between,
The variation of its pH value is less, close steady；The RG value of its fermentation liquid in 22h minimum 7.00 ± 0.250, between lactobacillus plantarum with
Between Pediococcus acidilactici (P < 0.05).
As shown in figure 4, three kinds of bacterium are with OD600The mixed-culture medium of nm value 1:1:1 inoculation enters logarithmic growth in 2h or so
Phase, OD between 2h~8h600The variation of nm value is very fast, has the section slow rise period between 8h~20h, 20h reaches maximum value 3.741
±0.003；The pH value variation of its same fermentation liquid also has two sections of variations, variation tendency and OD600Nm value is consistent, reaches in 22h
Minimum 4.24 ± 0.006；Its fermentation liquid RG value minimum 7.67 ± 0.289,6h~8h and at two sections of 14h~18h when for 24 hours
Between, there are two significant change (P < 0.05) for RG value.
The count plate of 2.2 strains
1 strain fermentation viable bacteria measurement result (lg cfug of table-1)
Significant difference (P < 0.05) is indicated with column data shoulder mark capitalization difference, indicates difference containing identical capitalization
Not significant (P > 0.05)
Significant difference (P < 0.05) is indicated with column data shoulder mark lowercase difference, contains identical lowercase letter indication difference
Not significant (P > 0.05)
By table 1 go together data it is found that lactobacillus plantarum culture solution between 4h~for 24 hours viable count significant difference (P <
0.05), 4h~16h is in logarithmic growth phase, 16h~be in the decline phase for 24 hours；Pediococcus acidilactici culture solution 4h~16h be in pair
In number growth period, viable count significant difference (P<0.05), 16h~be in stationary phase for 24 hours, viable count difference is not significant (P>0.05)；
Bacillus coagulans culture solution viable count significant difference (P < 0.05), 4h~10h between 4h~for 24 hours are in logarithmic growth phase,
10h~be in the decline phase for 24 hours；Mixed-culture medium viable count significant difference (P < 0.05) between 4h~for 24 hours, 4h~16h is in
Logarithmic growth phase, 16h~for 24 hours are in the decline phase, the viable count change curve of three of the above bacterium and its mixed-culture medium with
OD600nm value change curve trend is consistent.
By table 1 with column data as it can be seen that only three groups of data 12h Pediococcus acidilacticis and mixed-culture medium, 16h Pediococcus acidilactici
With bacillus coagulans culture solution, there was no significant difference for the viable count of lactobacillus plantarum and bacillus coagulans culture solution for 24 hours (P >
It 0.05), is significant difference (P < 0.05) between the culture solution viable count between other different strains of same time.At three kinds
Bacterium and its mixed culture for 24 hours during, lactobacillus plantarum, Pediococcus acidilactici, bacillus coagulans and its mixed-culture medium difference
Reach maximum value in 16h, 16h, 12h, 16h or so viable count.
The determination of 2.3 indicator bacteria aspergillus spore suspension concentration
Fig. 5 is that the aspergillus spore suspension of various concentration grows the comparison diagram after 48h, and spore suspension concentration is 103Spore/
Ml and 104Spore/ml plate, aspergillus flavus growth time need 5~7d, and experimental period is too long.Spore suspension concentration is 107Spore/
The plate of ml, because spore concentration is excessively high, aspergillus flavus mycelia growth and spore germination it is too fast, be not easy to observe bacteriostatic experiment as a result,
105Spore/ml and 106Selected in spore/ml, from from upgrowth situation and being easy to from the aspect of, therefore with 106Spore/ml
The bacteria suspension of concentration carries out bacteriostatic experiment.
The bacteriostatic diameter of 2.4 strain fermentation supernatant concentrates
Fig. 6 is the inhibition aspergillus flavus effect picture of the supernatant concentrate of three kinds of bacterium and its mixed culture.From table 2 it can be seen that
With concentration for 106Spore/ml aspergillus flavus is the antibacterial straight of six groups of data of indicator bacteria, wherein lactobacillus plantarum and Pediococcus acidilactici
Diameter maximum (P < 0.05).
The measurement result of supernatant concentrate antibacterial circle diameter is as shown in table 2 after strain fermentation:
The measurement result of supernatant concentrate antibacterial circle diameter after 2 strain fermentation of table
Note: colleague's data shoulder note lowercase difference indicates significant difference (P < 0.05), identical, indicates that difference is not significant
(P>0.05)。
3 discuss
Present invention combination lactobacillus plantarum, Pediococcus acidilactici, bacillus coagulans are individually cultivated and the life of mixed-culture medium
Long curve, pH value, RG value, count plate and the bacteriostatic diameter to aspergillus flavus, OD600nm value, pH value, the RG value of mixed-culture medium
And viable count maximum value, during the fermentation between three kinds of bacterium, the bacteriostatic diameter of supernatant concentrate is situated between after fermenting for 24 hours
Between three, and the logarithmic growth phase being mixed is obviously elongated, thus it is speculated that three kinds of bacterium growth in mixed cultivation process
It might have sequencing, reason needs further to be studied.
Test result of the present invention, lactobacillus plantarum provided by the invention, Pediococcus acidilactici, bacillus coagulans are independent or mixed
The concentrate for closing the fermented supernatant fluid of fermentation can inhibit the growth of aspergillus flavus.
4 conclusions
The supernatant of Pediococcus acidilactici, lactobacillus plantarum, bacillus coagulans and its mixed culture is found in bacteriostatic test
Concentrate has inhibiting effect to the growth of aspergillus flavus；Pediococcus acidilactici, lactobacillus plantarum, bacillus coagulans and its three are mixed
Close culture supernatant concentrate bacteriostatic diameter be respectively 15.860 ± 0.050mm, 15.737 ± 0.155mm, 14.287 ±
0.096mm and 15.173 ± 0.032mm；Wherein lactobacillus plantarum and the bacteriostatic diameter of Pediococcus acidilactici are maximum (P ﹤ 0.05).
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
