Problems solved by technology

However, due to the need to ferment under absolute anaerobic conditions, and the raw material is specific distiller's grains, and the entire production cycle is long (combined with Trichoderma viride step by step), there are many inconvenient factors
[0005] Rhodospirillum rubrum is a purple non-sulfur bacterium among photosynthetic bacteria. There has been a lot of research on its use in hydrogen production and sewage treatment, but there is no report on its solid-state fermentation for feed production.

Abstract

The invention relates to a fodder preparation method converting Rhodospirillum rubrum into various byproducts containing cellulose. The method includes mixing raw materials and acid solution evenly; adding CaCO3 to perform the first neutralization after heating and heat insulation; adding ammonia solution, sealing, insulating heat, cooling, and acquiring PH 7 by adjusting through acid; adding Rhodospirillum rubrum fermentation agent, mixing with cellulase evenly before fermentation for 6 to 7d, and obtaining the Rhodospirillum rubrum fermented solid fodder after drying. The method has the advantages that the cellulose material is degraded moderately, the raw materials are utilized completely to prepare high-protein and low-fiber fodder, the cellulose material value is increased, production cost is reduced, equipment requirement is lowered, and investment is reduced; limited acid hydrolysis is performed on the cellulose material, saccharification and fermentation are integrated into one step, preparation period is shortened, and process is simplified; the generality of the raw material is high, and reference is provided for expanding the wood fiber raw material application range.

Description

technical field [0001] The invention relates to a method for preparing high-protein and low-fiber feed by fermenting and transforming by-products containing cellulose with Rhodospira rubrum. It belongs to the field of recycling and utilizing cellulose-containing waste to produce biological feed products. Background technique [0002] Many industrial and agricultural by-products are rich in cellulose, common ones include liquor waste, straw, sauce residue and vinegar residue, etc. The recycling and reuse of cellulose by-products has become one of the hot and difficult research topics in the world. [0003] Cellulose by-products contain high content of cellulose, hemicellulose and lignin, and there is a complex and strong association between them. Using these raw materials to make products with higher added value (such as feed, etc.), More severe pretreatment methods are often required, which will inevitably increase the process cost and application difficulty. Such as 1.. ...
