Embodiment 1

[0052] The fermentation process of embodiment 1 clostridium butyricum fermented longan

[0053] (1) Extraction method of longan extract

[0054] Take dried longan, mash and homogenate, mix water and longan pulp according to the liquid-to-material ratio of 15ml:1g, and homogenize to obtain longan pulp slurry, the amount of cellulase added is 1.2% w / v, the enzymolysis temperature is 45.0°C, and the enzyme Under the condition that the hydrolysis time was 187.0min, the enzyme hydrolysis extraction experiment was carried out on a shaker with a rotation speed of 120r / min. After the extraction, the enzyme was inactivated in a water bath at 80°C for 10 minutes. Filter through eight layers of gauze, discard the residue, and obtain the supernatant. The supernatant was concentrated under reduced pressure to 40% of the original volume to obtain a longan extract.

[0055] (2) Standard curve creation

[0056]Accurately weigh 100mg of dried glucose, dissolve it with deionized water and s...

Embodiment 2

[0069] The fermentation process of embodiment 2 clostridium butyricum fermentation longan

[0070] (1) Extraction method of longan extract

[0071] Take dried longan, mash and homogenate, mix water and longan pulp according to the liquid-to-material ratio of 20ml:1g, and homogenize to obtain longan pulp slurry, the amount of cellulase added is 2% w / v, the enzymolysis temperature is 60.0°C, and the enzyme Under the condition that the hydrolysis time was 210min, the enzyme hydrolysis extraction experiment was carried out on a shaker with a rotational speed of 120r / min. After the extraction, the enzyme was inactivated in a water bath at 80°C for 10 minutes, filtered through eight layers of gauze, and the residue was discarded to obtain the supernatant. The supernatant was concentrated under reduced pressure to 30% of the original volume to obtain a longan extract.

Embodiment 3

[0085] The fermentation process of embodiment 3 clostridium butyricum fermented longan

[0086] (1) Extraction method of longan extract

[0087] Take dried longan, mash and homogenate, mix water and longan pulp according to the liquid-to-material ratio of 16ml:1g, and homogenize to obtain longan pulp slurry, the amount of cellulase added is 1.5% w / v, the enzymolysis temperature is 45.0°C, and the enzyme Under the condition of the hydrolysis time of 180min, the enzymolysis extraction experiment was carried out on a shaker with a rotation speed of 120r / min. After the extraction, the enzyme was inactivated in a water bath at 80°C for 10 minutes, filtered through eight layers of gauze, and the residue was discarded to obtain the supernatant. The supernatant was concentrated under reduced pressure to 30% of the original volume to obtain a longan extract.

Abstract

The invention discloses a biological fermentation product for preventing and treating animal colitis and a preparation method thereof, which has a certain preventive effect on colitis, and the invention has high stability. compared to a significant increase. It shows that the longan extract can promote the growth of Clostridium butyricum, further improve the product performance of probiotic preparations containing Clostridium butyricum, and play an important role in the field of bioengineering fermentation.

Description

technical field [0001] The invention relates to a biological fermentation product for preventing and treating animal colitis and a preparation method thereof, belonging to the field of bioengineering. Background technique [0002] As a feed additive, Clostridium butyricum can promote growth and improve feed conversion rate, and it is a strain with great utilization value and development prospect. However, the research time of Clostridium butyricum is not long. Compared with other probiotic-related microecological preparations, the research of Clostridium butyricum probiotics is still in its initial stage. There are certain deficiencies in the probiotics containing Clostridium butyricum currently on the market. And liquid fermentation is the key step of producing Clostridium butyricum technology, wherein the character of fermentation medium, fermentation condition (temperature, pH and inoculum size etc.) all can directly influence the level of liquid fermentation of Clostrid...
