Embodiment 1

[0032] (1) Preparation of seed medium

[0033] Neurospora crassa (Neurospora crassa ATCC10815) and black fungus (Auricularia auricula) were inoculated on PDA plates from the slant preservation tubes and cultured at 28°C for 10 days, and the colony morphology was shown in the figure ( figure 1 ). During the 10-day cultivation process, the seed medium was prepared;

[0034] Seed medium: 200 ml of milk factory waste water (after filtering to remove impurities, the total content of main components amino acid and protein 0.6%, oil 0.02%), add glucose 6g, peptone 4g, CaCl 2 0.07g, vitamin B 0.1g, vitamin C 0.1g, adjust pH 7.0-8.0. The culture medium was sterilized at 115°C for 30 min under high temperature and high pressure.

[0035] (2) Preparation of primary seed solution

[0036] On the PDA plate, 8 pieces of 0.5mm × 0.5mm bacterium blocks were picked, respectively inoculated in the seed culture medium of 200mL, and 26 ℃, 150rpm shake flask cultured for 3 days, as the first-...

[0046] (1) Preparation of seed medium

[0047] Neurospora crassa (Neurospora crassa ATCC10815) and black fungus (Auricularia auricula) were inoculated on PDA plates from slant preservation tubes and cultured at 28°C for 10 days. During the 10-day cultivation process, the seed medium was prepared;

[0048] Seed medium: 2000 ml of waste water rich in amino acids, milk factory waste water (after filtering to remove impurities, the total content of amino acids and protein in the main components is 0.6%, and oil 0.02%), add glucose 60g, peptone 30g, CaCl 2 0.6g, vitamin B 0.5g, vitamin C 0.5g, adjust the pH to 7.0-8.0. The medium was sterilized at 115°C for 30 min under high temperature and high pressure.

[0049] (2) Preparation of primary seed solution

[0050] Pick 20 pieces of 0.5mm×0.5mm bacterial pieces on the PDA plate, inoculate them in 2000mL seed culture medium respectively, and cultivate them at 26°C and 150rpm for 4 days as the primary seed solution.

Abstract

The invention discloses a method for preparing biological pigments by dual-bacteria fermentation using waste water rich in amino acids as a base material. The method uses Neurospora crassa and Auricularia auricula as fermentation strains, prepares a fermentation medium with waste water rich in amino acids, vibrates and ferments at 25-32°C, and extracts and concentrates the obtained fermentation liquid to obtain Biochrome. The invention utilizes amino acid-rich waste water to prepare a fermentation medium, and then utilizes dual-species coupled fermentation to produce pigments, effectively combines the treatment of amino acid-rich waste water and waste water resource utilization, and reduces the cost of producing biological pigments. The bio-pigment produced has the characteristics of high yield, environmental protection, strong ecological acceptability, etc., and has a good dyeing effect on protein.

Description

technical field [0001] The invention relates to a method for preparing biological pigments by double-bacteria fermentation using waste water rich in amino acids as a base material, and belongs to the field of microbial fermentation. Background technique [0002] It is the need of current development to greatly improve the large-scale production and application level of food and feed additives such as bio-pigments and bio-flavors. In recent years, countries around the world have successively formulated regulations to eliminate most toxic chemically synthesized pigments. Those natural pigments that have coloring functions, nutrition and health effects, and can endow food with new functions will have broad market prospects. The annual trade volume of natural pigments in the world is 1.3 billion US dollars, the annual demand is about 15,000 tons, and it is increasing at an annual rate of 11%. At present, most varieties of natural pigments come from plant extraction, but their d...
