Problems solved by technology

At present, the production of feed yeast in my country is mostly a solid fermentation method, and the raw materials used are mainly agricultural and sideline products containing starch or sugar, their dregs and industrial waste, etc., but at present, there is no application of multi-strain mixed inoculation to cultivate solid-state fermented aquatic plants to produce protein.

Abstract

The invention discloses a method of producing feed albumen by that microorganism state ferment hydrophytes, which is that crushed raw materials of hydrophytes or algae contain right water, encased in reactor with adding proper bran and urea after mixed uniformly; after sterilization adding cellulose decomposition mold with weight share 1%~5% to cultivate 12~48 hours, then inoculating microzyme with weight share1%~5% and cultivating 48~96 hours. For selected hydrophytes or algae as raw materials, this invention not only improves ecology environment but also bring economics benefit, and increases clearly albumen quality in product as mutual action of mold and microzyme during the fermentation process.

Description

1. Technical field [0001] The invention relates to a method for microbial solid fermentation, in particular to a method for producing protein feed through microbial solid fermentation of aquatic plants. 2. Background technology [0002] At present, in the ecological restoration of lake eutrophication, a large number of artificial planting of aquatic higher plants is adopted for algae-type eutrophic lakes, and water plants are used instead of algae to transform the ecological structure of the lake; for grass-type eutrophic lakes, artificial A method of harvesting a large number of aquatic plants and establishing transfer channels for nutrients such as nitrogen and phosphorus in the lake. The comprehensive utilization of resources of a large number of aquatic plants is currently only limited to primary green feed for fisheries and raw materials for papermaking and building materials, and there are population degradation and low utilization rates due to the selective use of aqu...
