Problems solved by technology

The lipid-lowering effect of natural Chinese red yeast rice is very good, however, the content of lovastatin in red yeast rice is quite low, according to literature reports, the lovastatin content of general export red yeast rice powder is only 4mg / g, which greatly limits the Large-scale application of red yeast rice

Embodiment Construction

[0014] Cultivation method of Huaxi sporogenes: From mid-to-late April to May every year, pick off the swollen "tea bubble" of the new shoots of tea leaves in the Camellia oleifera forest. "Tea bubble" is oblate to round and hollow, white and loose sponge-like texture, about 2-3mm thick, light green on the surface, and the lower epidermis of the leaves still remains. Generally 35 ~ 48 ( ~ 55) mm large. It is covered with white powder. Suspend the tea brew on a sterilized glass slide or a PDA plate medium with double antibodies (potato 200g; sucrose 20g; agar 20g; tap water to make up 1000ml), let the spores eject freely, and then take out the carrier that is sprayed with basidiospores. Microcirculation sporulation was observed on slides and plates. The basidiospores of the tea cake pathogen emitted onto the glass slide reached 20.7x6.9μm after being cultured in a 32°C incubator under moisturizing conditions for 24 hours. At room temperature of 25° C., 3 to 4 germ tubes are p...

Abstract

The invention discloses a Sporobolomyces huaxiensis Liu, the mycological characteristics of which are: after the spore ejection method is used to separate tea cake pathogens, the basidiospores can be seen to swell to 20-25×6.5-8 μm after absorbing water under a microscope. After the first division, 4 germ tubes were produced, and a columnar microspore with a slightly thinner end was directly produced on the 1.2 μm long stalk. Mature microspores are generally (6~)7.2~7.8(~9)×1.2~1.5(~1.8) μm. Microspores reproduce by budding and are easily dispersed. The above shows that after inducing the microcirculation sporulation of the basidiospores of the tea cake pathogen, it is found that the sexual basidiospores are shot on the glass slide, and after absorbing water and swelling, a slightly thinner end will be directly produced on the small stalk of the germination tube in the form of germination. Reproduce columnar microspores. The invention also discloses the use thereof, which can stimulate the germination of plant seeds and increase the content of lovastatin in monascus fermented products.

Description

technical field [0001] The present invention relates to tea cake pathogen (Exobasidium vexans Massen), in particular to Sporobolomyces huaxiensis Liu, and also relates to its use. Background technique [0002] At present, lipid-lowering drugs appearing on the market include lovastatin, simvastatin, pravastatin, fluvastatin, atorvastatin, cerivastatin, Zhibituo, Xuezhikang, etc. Their blood lipid-lowering mechanism All are related to lovastatin (also known as Monacolin K), and are all a series of drugs after structural modification of lovastatin. These chemically synthesized lipid-lowering drugs all have certain toxic and side effects. Natural Chinese red yeast rice has a good lipid-lowering effect. However, the content of lovastatin in red yeast rice is quite low. According to literature reports, the lovastatin content of generally exported red yeast rice flour is only 4mg / g, which greatly limits the Large-scale application of red yeast rice. With the improvement of people...
