Embodiment 1

[0064] A compound microbial enzyme of the present invention is composed of 100% cellulase, wherein the selected cellulase has an enzyme activity of 200,000 μ / g. Take 100ml seaweed slurry, add the complex microbial enzyme to form a mixed solution in a ratio of 0.4% to the slurry made from sea bath or seaweed residue, keep it warm for 25 hours, and measure the content of alginic acid in the supernatant to be 17.25% g / L.

Embodiment 2

[0066] A compound microbial enzyme of the present invention is formed by mixing 60% cellulase and 40% pectinase by mass percentage, wherein the selected cellulase has an enzyme activity of 120,000 μ / g, pectin The enzyme activity is 12,000 μ / g. Take 100ml of seaweed slurry, add the compound microbial enzyme to form a mixed solution in a ratio of 0.4% to the slurry made from sea bath or seaweed residue, keep it warm for 25 hours, and measure the content of alginic acid in the supernatant to be 19.56 g / L.

Embodiment 3

[0068]A compound microbial enzyme of the present invention is formed by mixing 60% cellulase, 35% pectinase and 5% protease by mass percentage, wherein the selected cellulase has an enzyme activity of 120,000 μ / g, the enzyme activity of pectinase is 10,500 μ / g, and the enzyme activity of protease is 25,000 μ / g. Take 100ml of seaweed slurry, add the complex microbial enzyme to form a mixed solution in a ratio of 0.4% to the slurry made from sea bath or seaweed residue, keep it warm for 25 hours, and measure the content of alginic acid in the supernatant to be 21.32 g / L.

Abstract

The invention relates to a preparation method of seaweed biological feed additive or seaweed biological feed. The preparation method is characterized in that compound microbial enzyme is added into seaweed slurry prepared from seaweed or seaweed residue for carrying out enzymolysis, so that the seaweed biological feed additive is obtained, wherein the compound microbial enzyme is prepared from multiples in cellulase, pectinase, protease and amylase. The preparation method provided by the invention is simple in process, easy to operate and low in cost; furthermore, the feed prepared by the method is rich in nutrition and easy to absorb.

Description

[0001] This application is a divisional application filed on August 26, 2014 by Weihai Shidai Marine Biotechnology Co., Ltd. with the title of invention "A Seaweed Biological Feed and Its Preparation Method" and the application number "201410425437.X". technical field [0002] The invention relates to the field of feed production, in particular to a seaweed biological feed which is enzymatically hydrolyzed by a compound enzyme and a preparation method thereof. Background technique [0003] As a large agricultural and aquatic country, my country has become an important animal protein consumption product for people, and it is growing geometrically every year. With the continuous increase of people's consumption level of aquatic products, it has greatly stimulated the rapid development of my country's aquaculture industry, especially the aquaculture with seaweed as food source, such as abalone and sea cucumber. Seaweed plants are rich in nutrients and have medicinal and health ...
