Embodiment 1

[0032] 1. Hydrangea liquid stock culture

[0033] (1) Mother species activation. Inoculate hydrangea in PDA (peeled potatoes 200g, glucose 20g, agar powder 16g) slant medium, and culture at 23-25°C for 25 days to obtain activated hydrangea parent species;

[0034] (2) Prepare the liquid stock. Peeled potatoes 200g sliced, add 1L water to boil, filter and add glucose 20g, peptone 2g, KH 2 PO 4 3g, MgSO 4 ·7H 2 O 1g, after stirring evenly, set the volume to 1L, and adjust the pH to 5.5;

[0035] (3) Divide the above-mentioned liquid culture medium into 250ml Erlenmeyer flasks, with a liquid volume of 100ml, and sterilize with high-pressure steam for 30 minutes;

[0036] (4) After sterilization, inoculate 5-8 pieces of activated slant mother species (0.5cm × 0.5cm), culture in a shaker with a rotation speed of 150rpm and a temperature of 23-25°C. After 10 days of cultivation, the liquid mother species will be obtained.

Abstract

The invention belongs to the technical field of industrial cultivation for edible funguses, and particularly relates to a sparassis crispa liquid strain culture medium and a culture method. The formula of the culture medium comprises 0-145 g/L of glucose, 0-70 g/L of glutinous rice flour, 1-6 g/L of fish meal peptone, 0-5 g/L of KH2PO4 and 0-3 g/L of MgSO4.7H2O, the original pH is 5-6, and the culture medium is cultured by preparation of sparassis crispa liquid mother strains and preparation of sparassis crispa liquid original strains. Aiming at the defects that the sparassis crispa liquid culture medium is high in cost and limited in raw material sources, the invention provides the sparassis crispa liquid strain culture medium and the culture method. The production cost is reduced, and the production efficiency is improved. The liquid culture medium has the advantages of being simple in formula and convenient in raw material sources and is suitable for large-scale production. The liquid strain culture process is simple, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of industrial cultivation of edible fungi, and in particular relates to a hydrangea liquid culture medium and a cultivation method. Background technique [0002] Hydrangea ( Sparasis latifolia ), also known as hydrangea mushroom and hydrangea mushroom, are named for their zigzagging and huge hydrangea-shaped seeds. They are known as dreamy and magical mushrooms in Japan. It is as rare as Cordyceps sinensis, morels, truffles and other treasures. According to the measurement, the content of crude protein and crude fiber is 12.9% and 13.7% in the dry fruiting body of Hydrangea hydrangea. (30.6 mg / kg) and so on are relatively high, and the vitamin content is also very rich, such as vitamin C, vitamin D, vitamin E, etc., among which the content of vitamin E ranks in the forefront of bacteria and algae foods in the "Food Composition Table". Hydrangea is not only delicious, high nutritional value, but also has g...
