Bran is rich in nutrients, including non-starch polysaccharides, starch, fat, lignin, protein, vitamins, phenolic substances, and many other components. However, it also contains crude fiber and phytic acid, which limits its full application in feeds. As an important by-product of agricultural processing, bran can be fermented to improve its nutritional value, and its end product is bio-fermented feed for animal breeding.
Lifeasible can significantly improve the application of bran in animal feeds through microbial fermentation technologies (mono-bacterial fermentation and complex bacterial fermentation). During the fermentation process, we degrade the proteins, carbohydrates, and fatty acids in the bran to low molecular small peptides, oligosaccharides, and free fatty acids using a variety of fermentative strains. This reduces the content of anti-nutritional factors such as cellulose in the bran and makes it easier for animals to absorb and utilize. The fermentation process also allows the bran to produce a variety of vitamins (B vitamins, vitamin K and vitamin C).
Selection of the fermentation strains we offer
| Types |
Use |
Strains |
| Bacillus |
During the fermentation process, it can produce a variety of metabolites, such as enzymes, organic acids, lactic acid bacteriocins, etc. These products can inhibit and kill certain harmful microorganisms and improve the animal's intestinal health environment. |
- Bacillus subtilis
- Cellulase producing Bacillus subtilis Kpg
- Bacillus subtilis var. natto
|
| Lactobacillus |
Its fermentation metabolites can significantly reduce the environmental pH and have a strong inhibition effect on the miscellaneous bacteria in the material. |
|
| Yeast |
During the fermentation process, it can produce a large amount of protein, nucleic acid, vitamins, and many kinds of enzymes, so that the content of the target product in the fermentation matrix can be increased and the quality can be improved. |
- Saccharomyces cerevisiae
- Candida utilis
|
| Mold fungus |
It can secrete arabinanase, phytase, protease, amylase, xylanase, lipase, cellulase, and glutaminase in fermentation. Therefore, it can effectively degrade cellulose and hemicellulose, destroy the dense structure of the bran cell wall, and release the ferulic acid bound on bran dietary fiber. It also hydrolyzes polysaccharides and phytic acid into oligosaccharides and inositol, respectively, to increase the content of soluble dietary fiber. |
- Aspergillus niger
- Aspergillus oryzae
- Trichoderma reesei
- Aspergillus clavatus
|
Fermentation process optimization services
Lifeasible used statistical methods (one-way test method, orthogonal experimental design, PB experimental design, steepest climb test, and response surface methodology) to optimize the bran fermentation process. This allowed identifying the main influencing factors in the bran fermentation process, to reduce the project time and to increase the target product content.
- We used Bacillus subtilis in combination with Saccharomyces cerevisiae for solid fermentation of bran, which significantly increased the bran polysaccharide content (130-198 mg/g).
- We used Bacillus subtilis in combination with Aspergillus niger, Saccharomyces cerevisiae, and Enterococcus faecalis for polymicrobial fermentation of bran, which could reduce the cellulose content to 5.32%.
- We used yeast and Aspergillus niger mixed bacteria to ferment bran so that the crude protein content of bran increased to more than 20%.
Fermentation can reduce the content of anti-nutritional factors in bran and release a variety of active substances, which play an important role in improving the animal's intestinal and organism health. Lifeasible provides services for bran fermentation, including strain selection and proportioning, fermentation process optimization, etc., to meet the needs of customers in the feed improvement and breeding industries.
