8cfu/mL, now thalline is energetic.
(2) fermentation culture
By bacillus amyloliquefaciens (
bacillus amyloliquefaciens) secondary seed solution of K-8, be 2%(V/V according to inoculum size) access in fermentor tank, the substratum used in each test and culture condition as follows respectively.
Test 1:
Adopt substratum 1: glucose 5g/L, molasses 10g/L, dried silkworm chrysalis meal 5g/L, corn steep liquor 5g/L, sodium-chlor 10g/L, calcium carbonate 1g/L, magnesium sulfate 0.1g/L, manganous sulfate 0.01g/L, iron protochloride 0.02g/L, pH7.0.

Test 2:
Adopt substratum 2: glucose 5g/L, molasses 20g/L, dried silkworm chrysalis meal 5g/L, corn steep liquor 15g/L, sodium-chlor 15g/L, calcium carbonate 5g/L, magnesium sulfate 0.5g/L, manganous sulfate 0.05g/L, iron protochloride 0.04g/L, pH7.3.
Culture condition: tank pressure 0.01MPa; 0h-8h: vapour-liquid ratio is 0.5:1, temperature 28 DEG C; 8h-24h: vapour-liquid ratio is 1:1, temperature 30 DEG C; After 24h: vapour-liquid ratio is 0.8:1, temperature 32 DEG C.Mixing speed: 150r/min.
Test 3:
Adopt substratum 3: glucose 10g/L, molasses 30g/L, dried silkworm chrysalis meal 10g/L, corn steep liquor 20g/L, sodium-chlor 20g/L, calcium carbonate 10g/L, magnesium sulfate 1g/L, manganous sulfate 0.1g/L, iron protochloride 0.08g/L, pH7.5.
Culture condition: tank pressure 0.01MPa; 0h-8h: vapour-liquid ratio is 0.5:1, temperature 28 DEG C; 8h-24h: vapour-liquid ratio is 1:1, temperature 30 DEG C; After 24h: vapour-liquid ratio is 0.8:1, temperature 32 DEG C.Mixing speed: 200r/min.
Test 4:
Adopt substratum 4: glucose 50g/L, starch 50g/L, protein powder 10g/L, yeast powder 20g/L, potassium primary phosphate 0.5g/L, manganous sulfate 0.05g/L, pH7.3.Contriver finds through test of many times, when the pH of substratum 4 is 7.0-7.5, in fermenting process viable bacteria content and spore content similar, when pH be greater than 7.5 or be less than 7.0 time, viable bacteria content and gemma can be reduced, therefore, controlling substratum 4 is herein pH7.3, carries out simultaneous test.
Culture condition: ventilation ratio is 1:1, mixing speed is 150r/min, tank pressure 0.01MPa, culture temperature 30 DEG C, incubation time are 48h.
Result is as shown in table 1 below.
The different culture condition of table 1 is on the impact of result
The medium component testing 1,2,3 three group is identical, and the content and the culture process that are nutrient media components are different.Test 1 compared with test 2, its highest viable bacteria content (52.9 × 10
8cfu/mL) lower than the highest viable bacteria content (75.8 × 10 of test 2
8cfu/mL).In this simultaneous test, the time that 1 microscopy gemma rate of testing reaches 100% is 32h, and viable bacteria content is now 47.3 × 10
8cfu/mL.And the time that 2 microscopy gemma rates of testing reach 100% is 28h, viable bacteria content is now 70.5 × 10
8cfu/mL.Namely the result testing 2 is better than test 1.
Test 3 is compared with test 2, and medium component is identical with culture process, and just the content of nutrient media components is different.In this simultaneous test, the time that 3 microscopy gemma rates of testing reach 100% is 28h, and viable bacteria content is now 60.7 × 10
8cfu/mL, lower than 70.5 × 10 of test 2
8cfu/mL.Namely the result testing 2 is better than test 3.
Test 4 for application number be the preferred cultural method of bacillus amyloliquefaciens disclosed in 201310070624.6 applications for a patent for invention.From table 1 data, its viable bacteria content reaches the highest by (71.7 × 10 when 32h
8cfu/mL), but due to the nutritive ingredient in substratum too abundant, therefore until 44h, in fermented liquid, microscopy just finds gemma, even if fermentation is to 48h, its gemma rate ability about 30%, viable bacteria content is now 38.4 × 10
8cfu/mL.
Consider the viable bacteria content in fermentation time, fermented liquid and these three factors of gemma rate, test 2 is best combinations.
the synergy of embodiment 2 inorganic salt
In order to investigate the impact on thalline fermentation and sporulation of part inorganic salt in fermented liquid, spy devises this simultaneous test.
The basic medium used in simultaneous test contains: glucose 5g/L, molasses 20g/L, dried silkworm chrysalis meal 5g/L, corn steep liquor 15g/L, sodium-chlor 15g/L, calcium carbonate 5g/L, pH7.0 ~ 7.5.
Culture condition is also identical:
Tank pressure 0.01MPa;
0h-8h: vapour-liquid ratio is 0.5:1, temperature 28 DEG C;
8h-24h: vapour-liquid ratio is 1:1, temperature 30 DEG C;
After 24h: vapour-liquid ratio is 0.8:1, temperature 32 DEG C.
Other composition added in each test and content as follows:
test 5:magnesium sulfate 0.5g/L, manganous sulfate 0.05g/L, iron protochloride 0.04g/L.
test 6:magnesium sulfate 0.5g/L, manganous sulfate 0.05g/L.
test 7:iron protochloride 0.04g/L.
Result is as shown in table 2:
Table 2 inorganic salt are on the impact of sporulation time and content
As seen from the results in Table 2, test 5 is when 28h, and namely microscopy gemma rate reaches 100%, and viable bacteria content is now 73.6 × 10
8cfu/mL, the time that 6 microscopy gemma rates of testing reach 100% is 32h, but now viable bacteria content is 65.4 × 10
8cfu/mL, the time that 7 microscopy gemma rates of testing reach 100% is 32h, and viable bacteria content is now only 62.1 × 10
8cfu/mL.As can be seen from this test, only in basal fermentation medium, add magnesium sulfate, manganous sulfate and iron protochloride simultaneously, 4h can be shifted to an earlier date and make gemma rate reach 100%, thus shorten fermentation time, cost-saving, make microbial inoculum be easy to processing, constant product quality.
