Water hyacinth edible fungus culture medium and preparation method thereof

Abstract

The invention provides a method for preparing an edible fungus culture medium from water hyacinth. The method comprises preparing slurry, removing heavy metals, press-filtering the slurry, sterilizing the slurry and carrying out mixing fermentation to obtain a finished product. The edible mushroom culture medium contains 20.5 to 22.8% of a crude protein, 3.5 to 4.6% of crude fat, 12 to 15% of crude fibers and 7 to 8% of monosaccharide. The medium can effectively cultivate 5 to 6 stubbles of edible fungi. The method realizes full fermentation of raw materials, cellulose and lignin are fully degraded, nutrient content of the culture medium is high, culture medium sterilization is more thorough, and the edible mushroom culture medium does not contain pathogens and pest eggs, does not pollute edible fungus cultivation and greatly improves safety. After being treated by a nanoporous ceramic composite filter plate, heavy metals in the water hyacinth slurry are effectively removed and culture medium safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of preparing edible fungus culture medium, and relates to a water hyacinth edible fungus culture medium and a preparation method thereof. Background technique [0002] Water hyacinth belongs to the hyacinth genus of Hyacinthaceae. It is a perennial floating herb. It was introduced from abroad as feed in the early years and was widely promoted in southern my country. Today, the eutrophication of water bodies is serious. After water hyacinth absorbs N and P nutrients in river water, it will rapidly multiply and spread in rivers, rivers, and lakes. At the same time, its decay stage will consume a large amount of dissolved oxygen in the water body, and the activities and breeding space of underwater animals will be reduced, causing a large number of aquatic animals to die and destroying the ecological balance of the water body. Therefore, how to reduce the harm of water hyacinth and make use of it to turn waste...

Problems solved by technology

[0005] The present invention aims at the problems in the existing technical field of using water hyacinth to prepare culture medium that the culture medium is not fermented sufficiently, the nutrient content is on the low side, and cannot meet the needs of the growth of edible fungi, and the culture medium contains pathogenic bacteria and harmful insect eggs, which are harmful to the cultivation of edible fungi. , and the problem that the heavy metal content in the culture medium is too high to endanger the safe production of edible fungi, a water hyacinth edible fungus culture medium and a preparation method thereof with low heavy metal content and high nutritional content are provided, and the specific scheme is:
