Embodiment

[0017] Referring to the production process of Bacillus subtilis fermented soybean meal in this embodiment, it includes the following specific steps:

[0018] (1) Activation of Bacillus subtilis strains, A. Preparation of Bacillus subtilis culture medium: 3g beef extract, 10g peptone, NaC15g, agar 2g, water 1000ml, and prepare Bacillus subtilis strain culture with pH 7.0~7.2 Base; B. Activation of Bacillus subtilis strains: transfer the Bacillus subtilis strains to the Bacillus subtilis strain medium for activation, and cultivate at 37°C for 24 hours;

[0019] (2) Liquid culture of Bacillus subtilis strains, A. Preparation of Bacillus subtilis strain liquid culture medium: prepare 3g beef extract, 10g peptone, 15g NaC, 1000ml water, pH 7.0-7.2, sterilize at 121°C for 30 minutes; B. Cultivating Bacillus subtilis strains liquid: pick the activated Bacillus subtilis strains to inoculate 5 ml of Bacillus subtilis liquid medium, and cultivate at 37°C for 24 hours;

[0020] (3) Bacillus su...

Abstract

The invention discloses a production technology of bacillus subtilis fermented soybean meal. The production technology comprises the following steps: (1) bacillus subtilis strain activation; (2) bacillus subtilis strain liquid culture; (3) bacillus subtilis strain culture in a triangular flask; and (4) soybean meal fermentation. The production technology is simple and easy to understand, by the use of bacillus subtilis, prawn diseases can be reduced, and the prawn yield can be greatly improved, so that the economic benefit and biological environmental friendliness are improved, aquatic animal immune organ development can be stimulated, immunity of the organism is enhanced, the prawn diseases can be reduced, and the prawn yield can be greatly improved, so that the economic benefit and biological environmental friendliness are improved, the water quality is purified, no pollution and residue can be produced.

Description

[0001] Technical field [0002] The invention belongs to a soybean meal production process, and specifically relates to a production process of Bacillus subtilis fermented soybean meal. [0003] Background technique [0004] Soybean meal is one of the important feed materials for animal husbandry and aquaculture, accounting for 80% to 90% of protein feed. Soybean meal is a by-product obtained by extracting soybean oil from soybeans. It is an excellent vegetable protein feed and the main protein raw material in animal feed. It has the advantages of high crude protein content, reasonable amino acid composition, and high animal digestibility and utilization. Rich in soybean isoflavones that can improve animal immunity, but soybean meal contains some anti-nutritional factors that affect animal nutrient digestion and physiological health, including antigen protein, phytic acid, soybean oligosaccharides, saponins, trypsin inhibitors, and urease It not only reduces the nutritional value ...
