technical field

As a new type of animal microbial feed additive, it has no toxic side effects, can promote animal growth, increase feed conversion ratio, improve animal digestive tract micro-ecological environment, and enhance animal immunity. From the perspective of bionics, how to cultivate aerobic probiotics with optimized conditions and high-efficiency solids, and how to quickly dry probiotic culture materials at low temperatures has become a large-scale factory production in the field of biological fermentation. The bottleneck has attracted much attention. Especially in today's overuse of antibiotics, it is an important research work related to the national economy and the people's livelihood to actively seek alternatives to antibiotics and develop green farming on a large scale. At present, the industrial production method of solid culture of probiotics is still limited to static culture and manual stirring, which is manifested by insufficient oxygen supply, high internal temperature of the piled material, uneven temperature, unstable humidity, and severe anaerobic fermentation, etc. In this case, the number of live bacteria of aerobic probiotics is not high, and the activity is poor. Although the number of probiotic spores may reach a certain level in the final product, the yield is not high. In addition, manual mixing of culture materials will lead to passive inhalation of bacterial spores into the respiratory system of operators, causing conditional disease. The accompanying problem is how to quickly dry the culture material after the completion of aerobic biological fermentation at a lower temperature (≤50°C), which is also the current industrialized production of probiotic solid fermentation and the industrialization of various biopharmaceuticals and food fermentation fields. A big problem facing production.

At present, the research and application of functional microecological feed additives is one of the hotspots in the development of animal husbandry production. Beneficial bacteria and their metabolites have extremely high functions of body metabolism regulation and nutrition, and are an effective means to alleviate the current situation of antibiotic abuse. It is one of the science and technology application projects that the relevant functional departments of the state are currently vigorously promoting. The factory production equipment technology in the fields of various biopharmaceuticals and food production also needs to be upgraded.

As the main key equipment of biological fermentation such as probiotics, the present invention can directly use the raw materials of agricultural and sideline products to carry out large-scale oxygen-enriched biological fermentation production, and the use of solid fermentation can make functional animal microbial feed additives more efficient than the current liquid fermentation. The production efficiency and product quality of such products are greatly improved, the production cost is greatly reduced, the market application prospect is broad, and the improvement of its economic benefits will be extremely significant.

2 Experimental results and analysis

2.1 Solid ecological culture of Bacillus amyloliquefaciens

2.1.1 pH dynamic changes (Figure 10):

The average pH values of the three batches of solid culture tests were between 6.4±0.06 and 7.1±0.09, and the average pH range after the initial 4h was 6.6±0.20. During the fermentation process, the pH decreased significantly in the first 16 hours, and after 16 hours, the pH value showed a slight upward trend.

2.1.2 Dynamic changes in temperature (Figure 11)

The temperature of the three batches of solid ecological cultivation experiments was controlled at 35.0±1.0°C. It can be seen from Figure 11 that the average value of the three continuous cultivation temperatures was between 36.47±0.088 and 37.20±0.115, and the temperature remained stable with little change.

2.1.3 Humidity dynamic changes (Figure 12)

The humidity of the 3 batches of solid ecological culture tests was controlled at 75±5.0%. It can be seen from Figure 12 that the average value of the humidity in the three consecutive cultures varied between 83.33±0.333% and 86±0.577%. Humidity is relatively stable.

2.1.4 Dynamic change of viable bacteria count (Figure 13)

During the three batches of solid ecological culture tests, the number of viable bacteria changed regularly, and the number of viable bacteria was relatively low at the beginning of fermentation 0 to 4 hours, which may be due to the short-term effect of Bacillus amyloliquefaciens on the new environment after being inoculated into the solid medium. The adaptation process, the vitality is low. After 4-16 hours, the vigor of the bacteria gradually increased, and after 16 hours, Bacillus amyloliquefaciens grew rapidly, and the number of bacteria increased rapidly. From 16 to 28 hours, the number of viable bacteria increased rapidly, and during this process, spores were continuously formed.

2.2 Drying of Bacillus amyloliquefaciens solid ecological culture (Figure 14)

After drying for 6 hours, the three batches of solid ecological cultures had water contents of 9.0%, 8.3%, and 8.6%, respectively, with an average of 8.63%±0.203, which met the national standard for water content of solid fermented products after drying.

2.3 The spore rate of Bacillus amyloliquefaciens solid ecological culture after drying (Figure 15)

After the 3 batches of solid ecological cultures were dried for 6 hours, the spore rates were 78%, 80%, and 85%, respectively, with an average of 81±2.1%, indicating that the solid ecological cultivation and drying integrated machine of the patent application has a great impact on the overall solid ecological cultivation and The control of the drying process is very good.

3 Discussion

3.1 Evaluation of fermentation effect by precise control of fermentation conditions

In this study, the self-developed solid ecological cultivation and drying machine was used to study the solid fermentation process of Bacillus amyloliquefaciens. From the perspective of ecological bionics, the relevant fermentation parameters are intelligently and rationally controlled, so that the whole fermentation process has good stability and Features of high efficiency.

3.2 The effect of controlling the relatively stable pH value on the solid fermentation effect

The appropriate pH level is a very important condition parameter for the growth of probiotics and the synthesis of metabolites, and it is also a comprehensive reflection of metabolic activities. In this study, the temperature and humidity of the fermentation substrate were relatively stable, showing a gradual decline in the pH value at the stage of 0-16h in the early stage of fermentation, reflecting the rapid increase in the activity of probiotics and the gradual increase in the acidic products of metabolism; However, at the 16-28h stage in the late stage of fermentation, the pH value tends to rise gradually. This is because the solid ecological cultivation and drying all-in-one machine of the present invention can rotate and stir the cultivation materials and fully supply air and oxygen with suitable temperature and humidity, which can effectively buffer the gradually falling pH in the cultivation process. The pH value, and the fluctuation of the overall pH value is controlled within a small suitable range, which better maintains the relative stability of the pH value in the overall fermentation and cultivation process, and at the same time, the number of viable bacteria shows a rapid increase. It may be due to the sufficient oxygen supply during the cultivation process, and the increase of dissolved oxygen in the culture material in the later stage of cultivation

3.3 Effect of temperature control on solid fermentation effect

The solid ecological cultivation and drying all-in-one machine of the present invention uses a microcomputer to automatically control the cultivation temperature to 35°C±1.0°C, and the temperature control is stable throughout the fermentation process, which helps to maintain a high enzyme activity state, which is in line with the growth of Bacillus amyloliquefaciens The need for optimum growth temperature range for propagation. More importantly, due to the rotation and stirring of the cylinder, the fermentation temperature of all culture materials is guaranteed to be uniform and the oxygen supply is sufficient, which meets the needs of the optimum growth temperature range for the growth and reproduction of Bacillus amyloliquefaciens and effectively improves the quality of fermentation culture.

3.4 Effect of humidity control on solid fermentation effect

The research equipment automatically controls the stability of the culture humidity through the intelligent temperature and humidity meter, and also controls the stability of the culture temperature. When the humidity of the culture material changes, it will automatically start or shut down the spray liquid device of the humidity automatic control and bacterial liquid inoculation input system to control the culture humidity, and start the fan and drum at the same time to ensure that the water content of the material is uniform. In this study, the humidity of solid fermentation was controlled at 75±5.0%, and the results showed that it could meet the suitable range of humidity required for the growth and reproduction of Bacillus amyloliquefaciens. It is due to the uniform and gentle material automatic humidification function of the liquid input device, which meets the needs of the optimum growth humidity range for the growth and reproduction of Bacillus amyloliquefaciens. The set humidity value is slightly lower than the actual measured value, because the humidity sensor of the solid ecological cultivation and drying all-in-one machine of the present invention is arranged at the air outlet of the automatic rotating cylinder, the automatic humidification function of the liquid input device and the feedback information of the humidity sensor There is a delay in time, which will increase the humidity value. In addition, under certain temperature conditions, the humidity value will also increase. Therefore, considering the influence of these factors, it can be used to guide the setting of humidity.

3.5 The influence of the closed inoculation method of liquid strains on the fermentation efficiency of the solid ecological cultivation and drying all-in-one machine

The solid ecological cultivation and drying all-in-one machine can inoculate the culture material evenly by mixing the seed liquid through the inoculation system and the wind distributor in a closed and sterile state. Its characteristics are as follows: safe, fast, uniform, and simple, especially in the initial stage of probiotic culture, the anti-microbial infection effect is relatively ideal.

3.6 Characteristics of dynamic changes in the number of viable bacteria during the cultivation process

Under the specific culture conditions of this study, the number of viable Bacillus amyloliquefaciens showed a dynamic change that continued to increase throughout the fermentation process. The initial stage of fermentation culture belongs to the growth lag period, and the number of viable bacteria does not increase significantly, but the pH value of the culture material gradually decreases, and the acidic products of metabolism gradually increase, reflecting the rapid increase in the activity of probiotics. A sharp upward trend belongs to the growth index period of bacteria, and the metabolism is vigorous. The research results reflect that the control of the relevant culture conditions in the culture process is more appropriate.

3.7 Change characteristics of moisture content and spore rate of culture after drying

After the culture material is dried, the average water content of the Bacillus amyloliquefaciens powder is 8.633% ± 0.203, and the average spore rate is 81% ± 2.081, which meets the relevant national product quality control requirements. In this study, the hot air temperature control system, automatic stirring system, and cyclone separation and recovery device are used at the same time, and the rapid low-temperature air drying condition of 43±2°C is maintained. The results show that the surface area of the culture material can be greatly increased, and the efficiency is high. Remove the moisture in the culture material, effectively maintain the quantity and activity of probiotics, and achieve the ideal effect of rapid temperature-sensitive drying but maintaining the activity of the bacteria.

3.8 Evaluation of the working effect of the solid ecological cultivation and drying machine

The solid ecological cultivation and drying process of Bacillus amyloliquefaciens is studied through the patented solid ecological cultivation and drying machine of this application, and the relevant structure is developed from the perspective of bionics. The automatic stirring system regulates the work of the drum, which can automatically control aerobic Stirring intensity of the biological fermentation substrate, and make the material fully obtain oxygen and ferment evenly. The temperature and humidity control system, through the wind distributor, can make the uniformly stirred materials in an ecological-like cultivation environment with suitable temperature and humidity, so as to ensure the efficient cultivation of probiotics.

The seed liquid inoculation input system can safely and quantitatively inoculate the seed liquid in a closed manner, and can effectively achieve a better closed state, so that the rate of miscellaneous bacteria is controlled below 1%.

In this study, the working conditions of aerobic fermentation culture automatically controlled by the solid ecological cultivation and drying machine were set as follows: temperature 35.0±1.0°C, humidity 75±5.0%, initial pH 7.2±0.2 (adjusted during the preparation of solid medium pH), the tumbler was stirred for 1min and rested for 5min, the cultivation time: 28 hours, and the average bacterial content in the final fermentation material reached 203.333±4.410×10 ⁸ CFU/g; the working condition of automatic control temperature-sensitive drying was set as: temperature 43± At 2°C, the drum was stirred for 1 min and rested for 3 min. The average spore rate was 81±2.081%, and the average water content was 8.633±0.203%. During the temperature-sensitive drying process of materials, the drying hot air temperature control system continues to work, and the cyclone separator can effectively recover the material powder that escapes with the air flow. Compared with the liquid fermentation process, the production of aerobic biological fermentation is significantly improved, the production cost is greatly reduced, and the requirements for large-scale production of aerobic probiotic factories can be fully met.
