Embodiment 1

[0027] Example 1: Comparison of Astaxanthin-producing Ability of Different Yeast Strains and Formula Optimization of Yeast Medium

[0028] 1 Materials and methods

[0029] 1.1 Bacteria used in the test

[0030] Rhodotorula viscosus (N), Rhodotorula deep-glucose (SN), Rhodotorula marine (H), and Rhodotorula (R8) are existing yeasts in the Biological Research Institute of Shandong Baolai Lilai Bioengineering Co., Ltd.

[0031] Phaffia rhodozyma (R5) was purchased from China Industrial Microorganism Culture Collection and Management Center, the strain number is CICC33064, and it is a yeast strain capable of producing astaxanthin.

[0032] 1.2 Comparison of astaxanthin-producing ability of different yeast strains

[0033] Using the basic formula of yeast culture medium as the fermentation medium, different yeast strains were fermented and cultured, and their ability to produce astaxanthin was determined by the dimethyl sulfoxide method.

[0034] The basic formula of the yeast m...

Embodiment 2

[0063] Embodiment 2: the preparation of biological color enhancer

[0064] 1 Raw material composition

[0065] Consists of the following raw materials in parts by weight:

[0066] 70 parts of Phaffia rhodozyme spray-dried powder, 10 parts of Phaffia rhodozyme freeze-dried powder, 10 parts of lactic acid bacteria fermentation product, 6 parts of antibacterial peptide, 3 parts of stone powder, and 1 part of glutamine.

[0067] Among them, the spray-dried powder of Phaffia rhodozyme and the freeze-dried powder of Phaffia rhodozyme are prepared by spray-drying and freeze-drying the fermented liquid obtained by fermenting and culturing Phaffia rhodozyme on a yeast medium. Fermentation cultivation, spray drying, and freeze drying operations are all conventional technical means in the prior art.

[0068] Phaffia rhodozyma was purchased from China Industrial Microorganism Culture Collection and Management Center, the strain number is CICC33064, and it is a yeast strain capable of pr...

Embodiment 3

[0074] Embodiment 3: the preparation of biological color enhancer

[0075] Raw material composition:

[0076] 60 parts of Phaffia rhodozyme spray-dried powder, 12 parts of Phaffia rhodozyme freeze-dried powder, 8 parts of lactic acid bacteria fermentation product, 8 parts of antibacterial peptide, 2 parts of stone powder, and 1.5 parts of glutamine.

[0077] The preparation method is the same as in Example 2.

Abstract

The invention discloses a biological color enhancing agent which is prepared from 60-80 parts of Phaffia rhodozyma spray dry powder, 8-12 parts of Phaffia rhodozyma freeze-dried powder, 8-12 parts of a lactic acid bacteria fermentation product, 4-8 parts of antimicrobial peptide, 2-4 parts of mountain flour and 0.5-1.5 parts of glutamine. The invention further discloses a preparation method of the biological color enhancing agent and application of the biological color enhancing agent to aquatic animal breeding. According to the biological color enhancing agent, Phaffia rhodozyma serves as the effective ingredient, the nutritious value is rich, the content of protein is high, and the biological color enhancing agent is rich in multiple types of microelements and coenzyme, further rich in astaxanthin and configured with multiple types of nutrient substances and has the advantage of being stable in color enhancing effect in serving as the color enhancing agent for aquatic animal breeding.

Description

technical field [0001] The invention relates to a biological color enhancer and its application in aquatic animal breeding, belonging to the technical field of aquatic animal breeding. Background technique [0002] With the rapid development of artificial aquaculture, changes in the environment, and changes in the food chain, the body color of aquaculture animals has changed to varying degrees. The fish and shrimps grown in the natural state are bright in color and delicious in meat quality, but under the conditions of artificial intensive farming, due to the extensive use of artificial compound feed, the breeding cycle of fish, shrimp, and crabs is shortened, and only a small amount of natural aquatic organisms can be obtained. There are few effective color sources and unstable ingredients in the feed, resulting in the lightening of the body color of fish, shrimp, and crabs, and channel catfish "turning white", "changing flowers" or even "turning black"; "black"; rice fiel...
