Embodiment

[0027] This embodiment provides a method for producing organic manganese by solid-state fermentation, which specifically includes the following steps:

[0028] 1. Activation of strains: Pick preserved strains of Lactobacillus and inoculate them into Lactobacillus culture medium, and culture them statically at 35-39°C for 24-36 hours to activate;

[0029] Among them, the components of the lactobacillus culture medium and the weight ratio of each component are preferably 1.0% sucrose, 1.5% beef extract, 0.25% yeast extract, 1.0% glycerin, 0.3% lactose, 0.05% ascorbic acid, K 2 HPO 4 0.5%, MgSO 4 0.25%.

[0030] 2. Strain cultivation: Lactobacillus cultures are inoculated in seed tanks with an inoculum of 1%-5%, and cultured at 35-39°C for 20-24h;

[0031] 3. Inoculum strain treatment: water: inoculum strain: sucrose: Tween-80 mixed according to the weight ratio of 40:10:2:1 to prepare the inoculum liquid;

[0032] 4. Inoculation in the fermentation workshop: the fermentation...

Abstract

The invention relates to a solid state fermentation based production method of organic manganese. The solid state fermentation based production method of organic manganese comprises the following steps of: activating lactobacillus; inoculating the activated lactobacillus against an inoculum in an inoculum tank, and culturing the inoculated lactobacillus; mixing the inoculated lactobacillus with sucrose and Tween-80, and culturing; mixing pure-grain solid raw materials with an inoculum solution, and fermenting to obtain a microbial fermentation substance; and combining the microbial fermentation substance with a manganese salt in a complexing way to obtain the organic manganese. Manganese ions are combined with small peptides in the microbial fermentation substance by adopting a solid state fermentation process. Experiments show that the produced organic manganese contains 8-20% of manganese, has the complexing strength of 15-30, can be used for producing feeds, is low in cost, is low in environment pollution and has great market development prospect. In addition, because small peptides serve as the carriers of manganese, the absorption and utilization rate of manganese can be increased greatly, and the utilization rate of vitamins in the feed can be also increased.

Description

technical field [0001] The invention relates to a fermentation technology, in particular to a method for producing organic manganese by solid-state fermentation. Background technique [0002] Trace elements play an important role in the growth maintenance and production activities of animals. Under modern production conditions, with the continuous improvement of animal production levels, the animal's demand for trace elements is also increasing. At present, the main method of supplementing manganese is to ignore the manganese content in the feed and add it according to the animal's needs. Inorganic manganese is easily absorbed into macromolecules by phytic acid, tannin or fiber in the intestinal tract of animals or rapidly degraded and excreted. Resulting in poor solubility and low absorption rate: while the molecular charge of organomanganese tends to be neutral, it has good solubility and high absorption rate under the suitable pH environment of animal digestive tract. S...
