Novel male silkworm cordyceps culturing process and method for culturing silkworm cordyceps parent species

Abstract

The invention relates to a novel male silkworm cordyceps culturing process comprising the following steps: (1) a silkworm cordyceps strain is selected; (2) a silkworm cordyceps parent species is cultured, and is prepared into a bacterium liquid; (3) male silkworm cordyceps culturing is carried out. A silkworm cordyceps parent species culturing method suitable for the novel male silkworm cordyceps culturing process comprises the following steps: (1) separation is carried out, wherein mature silkworm cordyceps fruiting bodies are separated and cultured in petri dishes; (2) transplanting is carried out, wherein silkworm cordyceps strains growing well in the peri dishes are transplanted into slant media in test tubes and are cultures; (3) rejuvenation is carried out, wherein the silkworm cordyceps strains on the slant media in the test tubes are prepared into the bacterium liquid; the bacterium liquid is injected into silkworm bodies, such that strain activity is enhanced; (4) mature silkworm cordyceps fruiting bodies grown on the silkworm bodies are subjected to separation and transplanting operations again according to the above steps (1)-(3). According to the invention, silkworm cordyceps is artificially cultured with male silkworm larvae as a host. Compared to a method for culturing cordyceps with silkworm pupa, labor is saved, and cost is low.

Description

technical field [0001] The invention relates to the field of Cordyceps cultivation, in particular to a novel male silkworm cultivation technique. Background technique [0002] Cordyceps sinensis is a precious Chinese herbal medicine, which has many significant medicinal activities such as nourishing the lungs and kidneys, stopping bleeding and reducing phlegm, anti-oxidation, anti-inflammation, and anti-cancer. According to modern medical analysis, cordycepin, cordyceps polysaccharide, adenosine, and cordycepic acid are The main active ingredient of Cordyceps, cordycepin has various pharmacological effects such as anti-tumor, anti-aging, antibacterial, anti-virus, immune regulation, improving metabolism, and scavenging free radicals; Cordyceps polysaccharide can improve human immune function and increase white blood cells, which has been used clinically It is used to treat malignant tumors; adenosine can expand coronary vessels and increase blood flow; cordycepic acid can pr...

Problems solved by technology

However, the following major problems still exist in the current artificial cultivation technology of Cordyceps: (1) The strain resources are degraded and the content of active ingredients is unstable; (2) The artificial cultivation conditions are harsh and it is difficult to achieve large-scale production; (3) The artificial Cordyceps products lack depth to develop

However, in the development and utilization of silkworm fungus, there are still problems such as unstable strains, harsh artificial culture conditions, and difficulty in achieving large-scale production.
