Embodiment 1

[0023] (1) Seed culture:

[0024] Prepare seed medium (glucose 30 g, soybean flour 20 g, glycerin 70 g, protein 2 g, NaNO 3 2 g, MgSO 4 1 g, water 1000 mL) 300 mL, placed in a 1000 mL Erlenmeyer flask, at 1.1kg / cm 2 Sterilize under pressure for 30 minutes, then inoculate purple red yeast rice ( Monascus purpureus Went., the strain preservation number is: CGMCC 3.5833) culture suspension of slant. Cultivate for 3-4 days in 28° shake flask at 200 rpm.

[0025] (2) Fermentation of purple red yeast rice:

[0026] The fermentation medium is composed of the following ingredients: 1000 mL of potato extract, 20 g of glucose, and natural pH. Take 200 grams of potatoes, cut them into small pieces, add 1.0 liter of water and boil for 30 minutes, filter out the potato pieces, and make up the filtrate to 1.0 liters.

[0027] Take 3 L of the above-mentioned culture medium and put it into a 5 L fermenter, at 1.1kg / cm 2 Sterilize under pressure for 30 minutes. Inoculate the above c...

Abstract

The invention relates to a preparation method of metalloenzyme widely existing in organisms, in particular to a preparation method of superoxide dismutase. The method is characterized by comprising seed culture, fermentation of monascus purpureus went., thalli disruption, crude enzyme acquisition and enzyme scouring and is specifically characterized by culturing the thalli, then using high pass oxygen to induce enzyme to express, using a homogenizer to disrupt the thalli, using 70% of ammonium sulfate for precipitation and using SephdexG-25 gel salt, thus obtaining the superoxide dismutase product. Compared with the prior art, the product has high enzyme expression quantity and recovery rate, saves energy and lowers the cost.

Description

technical field [0001] The invention relates to a preparation method of a metalloenzyme widely present in organisms, especially a preparation method of superoxide dismutase. Background technique [0002] Superoxide dismutase (superoxide dismutase, referred to as SOD) is a metalloenzyme widely present in organisms, which can catalyze the dismutation reaction of superoxide anion free radicals and balance oxygen free radicals in the body. Popular research topics in the field of study. As a cleaning agent for superoxide anion free radicals in organisms, SOD has unique functions in radiation protection, anti-aging, anti-inflammation, tumor and cancer suppression, autoimmune therapy, etc. Many applications. Therefore, the demand for SOD is also increasing. [0003] So far, people have isolated SOD from organisms such as bacteria, protozoa, algae, mold, plants, insects, birds, fish, and mammals. Therefore, people in the industry now have a wide range of sources for extracting SO...
