Description
Technical field
The present invention relates to microbial technology field, particularly Huperzia serrata endogenetic epiphyte and application thereof.
Background technology:
Selagine is as the specifics of a new generation treatment presenile dementia, and market outlook are considerable, and it is clinical that its derivative ZT-1 is just entering the III phase at the authentication registration of European EMEA, and product development is also actively being carried out.At present, selagine is mainly derived from Herba Lycopodii serrati (Huperzia serrata) herb.Though the Herba Lycopodii serrati resource area is wide, distribute and be scattered about like the stars, the resource updates cycle is long, can be fewer for the natural resource of commercial exploitation.Through a large amount of exploitations for many years, the Herba Lycopodii serrati resource of provinces such as Chinese Zhejiang, Jiangxi, Fujian is close to exhaustion.The resource of provinces such as Hunan, Guangxi, Sichuan also will face exhausted danger in two, three years.These areas are as the forfeiture gradually of Herba Lycopodii serrati compartmentation advantage kind status, thereby can not satisfy the demand of market to selagine by the Herba Lycopodii serrati natural resource of directly gathering.On the other hand, the chemosynthesis of selagine is low because of yield, cost is expensive, also is difficult to realize industrialization.Investigators attempt to obtain selagine by biotechnological means, and therefore, this has become the problem that people pay close attention in recent years.
Summary of the invention:
Technical problem to be solved by this invention is to design and a kind ofly can produces the selagine analogue by microbial fermentation.
The invention provides a kind of Huperzia serrata endogenetic epiphyte, give birth to branch top spore mould (Acremoniumendophytium) in the called after.
Huperzia serrata endogenetic epiphyte of the present invention adopts the endogenetic fungus separating and purifying technology to separate from pteridophyte Herba Lycopodii serrati (huperzia serrata) plant living body and obtains, and gives birth to branch top spore mould (Acremonium endophytium) in microbial taxonomy is accredited as.The preservation of this bacterial strain, preservation date are on November 13rd, 2006, and preserving number is CCTCC M 206118, and depositary institution is Chinese typical culture collection center, address: Luojia Mountain, Wuhan, Hubei Province Wuhan University, postcode: 430072.
The solid culture of Huperzia serrata endogenetic epiphyte of the present invention is characterized as:
28 ℃ of cultivations on potato dextrose agar (PDA) substratum, initial aerial hyphae is colourless, gradual change white; The bacterium colony circle, white, the fine hair shape, the edge is irregular, and the back side is khaki.
The liquid culture of Huperzia serrata endogenetic epiphyte of the present invention is characterized as:
(1) substratum PDA, shake-flask culture 7 days, 28 ± 1 ℃ of culture temperature;
(2) fermentation culture feature: cultivated 1-2 days, and do not see obvious growth phenomenon; Cultivated the 3rd day, and had a little white hypha to occur; Cultivated the 3rd day, and formed diameter 1-2mm white hypha ball; Cultivate the 4th day bacterium spherical diameter and increase to 2-4mm; Cultivated the 5th day, bacterium nodule number amount increases; Cultivated the 6th day, fermented liquid is sticky; Cultivated the 7th day, mycelium pellet is assembled.
The morphological specificity of Huperzia serrata endogenetic epiphyte of the present invention is:
1, asexual generation, the mycelia branch, level and smooth, have every, thick 1.2-1.5 μ m; In the product spore zone of young bacterium colony, the sporophore that the mycelia adnation is short, long 10-13 μ m; Conidium is avette to fusiformis, and is colourless, 3.53-5.44 * 1.16-1.32 μ m, and chain is concatenated.
2, sexual generation, do not find
