Hypsizygus marmoreus liquid strain fermenting technique

Abstract

The invention discloses a hypsizygus marmoreus liquid strain fermenting technique, comprising the following steps of: culturing a test tube seed; transferring the test tube seed to a shake flask; culturing the liquid strain in the shake flash; inoculating the strain of the shake flash in a fermentation tank; and then inoculating the strain of the fermentation tank in a strain package. The technique disclosed by the invention has the following advantages that the activity of the strain is high, the seed production period is short, the inoculating speed is high, the strain ages are the same, the pollution rate is low and the like; the liquid strain can be inoculated by using an inoculating gun, so that the semi-mechanization is realized, the efficiency is high, the manpower is saved, and the technique is suitable for being developed in the field of edible mushroom cultivation.

Description

technical field [0001] The invention belongs to the field of agricultural bioengineering, and specifically relates to a method for fermenting seafood mushroom liquid strains. Background technique [0002] Seafood mushroom, scientific name [Hypsizygus marmoreus (Peck) H.E.Bigelow], Chinese name: Zhenji mushroom, also known as jade mushroom, spot jade mushroom, crisp and tender texture, delicious taste, with sea crab flavor, called "crab flavor" in Japan Mushroom", "Seafood Mushroom". Seafood mushrooms are rich in nutrients and are edible mushrooms with great commercial potential in recent years. At present, most of them are cultivated in factories. [0003] At present, the cultivation of seafood mushrooms is a solid strain cultivation method. After the strains are cultivated on the solid inclined medium in the test tube, they are directly inserted into the bacterial bag from the test tube. The above-mentioned solid strain cultivation method completely relies on manual inocul...

Problems solved by technology

[0003] At present, the cultivation of seafood mushrooms is a solid strain cultivation method. After the strains are cultivated on the solid inclined medium in the test tube, they are directly inserted into the bacterial bag from the test tube. The above-mentioned solid strain cultivation method completely relies on manual inoculation, and the efficiency lower

In addition, the culture process of solid bacteria is static. Under static conditions, a nutrient-permeable barrier is formed around the bacteria or cultured cells, and the intake of nutrients is hindered, resulting in low activity of the bacteria. long, which indirectly leads to increased costs
