Paecilomyces hepialid mycelium and preparation method thereof

Abstract

The invention discloses a paecilomyces hepialid mycelium and a preparation method thereof. The mycelium is obtained by cultivating paecilomyces hepialid via a solid culture medium. The preparation method technically includes: dissecting fresh cordyceps sinensis polypide, separating a paecilomyces hepialid culture in the cordyceps sinensis polypide, cultivating and separating hetero-cultures out, preparing the solid culture medium for sterilizing, inoculating 10% by weight of cultivated and rejuvenated liquid culture on the culture medium for fermentation, and cultivating in an aseptic condition at the temperature of 20-22DEG C for 7-10 days to obtain the mycelium. The mycelium prepared by the preparation method is equal to natural cordyceps sinensis in aspects of nutrition and medical values. The paecilomyces hepialid mycelium is characterized in that under an ordinary 300-600-multiplication optical microscope, the mycelium is 16-40 micrometers in visible length and 3-5 micrometers in root width. The mycelium mainly comprises adenosine which cannot be dissolved by water and can be dissolved by ethyl alcohol.

Description

technical field [0001] The invention belongs to a kind of Cordyceps sinensis mycelium, which is a biological technology product. Products are widely used in medicine, food and health food. Background technique [0002] Cordyceps sinensis is neither a worm nor a grass, it is a complex of fungi and worms. On the Qinghai-Tibet Plateau at an altitude of 3,500 to 6,000 meters in China, there lives a cold-resistant insect called the bat noctuid. Its adult period is only 4 to 12 days, while its larval period is 680 to 940 days. A fungus called Cordyceps sinensis (scientific name: Paecilomyces bat moth or Trichosporum bat moth) is active at almost the same altitude. The larvae of a bat noctuid, Cordyceps sinensis, drill into the worm body to parasitize it. [0003] Bat moth larvae are usually infected at the end of autumn and early winter, and the fungus that invades the insect body develops into sclerotia about a month later. At the same time, the larvae of the bat moth stopped...

AI Technical Summary

Problems solved by technology

And the current culture of mycelium is because the second stage did not effectively control the problem of miscellaneous bacteria in the medium, resulting in being eaten by other faster-growing fungi during the cultivation process and turning into golden yellow mushrooms. The result is: the mycelium cannot be observed with a 600 times ordinary microscope
