Abstract
An application of high absorbance phycoerythrin produced by using Helminthocladia and its method are provided. Under the characteristics of sexual reproduction, asexual reproduction and vegetative reproduction in the life history of the helminthosporium and the fact that the filiform stage of the fruit spores does not contain various colloids, the filiform stage is continued under the controlled conditions of light, temperature and nutrition, and the high absorbance ratio phycoerythrin is extracted by taking the hyphostroma as a raw material. The aim of reducing the production cost and the purification steps of the phycoerythrin is achieved through the high weight ratio of the phycoerythrin contained in the unit weight.
Description
Technical field
The invention relates to helminthocladia (Helminthocladia australis) production and have the purposes and the method thereof of high absorbance (OD) ratio phycoerythrobilin.Utilize syngenesis, the monogony that helminthocladia has in the life history and nourish and generate three digenesis and carpospores filament stage do not contain under the feature of various glue classes, under light, temperature and the nutritional condition of control, continue its filament stage, and be raw material with it further, extraction has the phycoerythrobilin of high absorbance ratio.
Background technology
No matter with regard to phycoerythrobilin, algocyan or other natural protein pigment, usually has practical security, the stability that heat, potential of hydrogen etc. is also had certain degree, can be applicable on food and the makeup, simultaneously also can be used as the fluorochrome that the antibody sign is used on the immunology, be applied to clinical diagnosis and cellular biochemical and learn in the research.
Existing market has been developed and used algocyan (phycocyanin) and phycoerythrobilin (phycoerythrin), wherein, the raw material sources of algocyan production mostly are and can give the blue-green algae that a large amount of breedings are cultivated, as spirulina (Spirulina) and patina Microcystis aeruginosa (Microcystis), and it is cultivated and production method is enjoyed patent more.
Phycoerythrobilin is then because the shortage of raw material, or because raw material is unfavorable for pigment production, and exist output to reach expensive defective less, demand to the edible red pigments of the annual tens thousand of pounds in the whole world, must develop a kind of natural, safe, stable red pigments that special fluorescence disengages that has again, after estimating mass production, price will be descended, and more can enlarge its range of application and the market supply.
Algae haematochrome albumen major part is the large-scale thallus of separating from red algae at present, and as laver (Porphyra) or rosetangle algae (Ceramium) etc., small part then extracts from the Porphyridium cruentum (Porphyridium) that can control cultivation in a large number.Its subject matter is:
Though 1, the laver of wild a large amount of red algae resource and cultivation is arranged as the phycoerythrobilin raw material at present, but because most red algaes contain and enrich colloid (agar glue, carrageeman, Furcellaria gum), cause the collection of pigment to go out difficult, especially dried algae raw material is all the more so, the raw material of adding wild algae kind all has seasonal variation on product and output, by manpower is difficult for grasping.
2, at present Porphyridium cruentum be incubated at collecting cell the time, significant difficulty is also arranged, because the collection of unicellular frond one to be the power consumption and operation consuming time, cause production cost very big, and frustule secreted solubility Polysaccharides when cultivating, except the collection of block cell, also have influence on the extraction of pigment.
In order to solve the above problems, United States Patent (USP) 5,358,858 have proposed a kind of method of producing phycoerythrobilin by flagelliform nostoc (Bangiaatropurpurea) and narrow leaf laver (Porphyraangusta) filament, utilize flagelliform nostoc and the thread sporophyte stage of narrow leaf laver in the life history not to contain under the feature of various glue classes, under light, temperature and the nutritional condition by control, continue its filament stage, and be raw material with it further, the extraction phycoerythrobilin, its step is as follows:
1, the cultivation of filament and breeding, from sophisticated flagelliform nostoc of field acquisition or narrow leaf laver gametophyte, it is clean to clean frond with sterilization seawater and writing brush, the back input of drying in the shade slightly contains in SWM-III (as shown in Table 1) culture dish of improveing, the culture dish inner bottom part is covered with cover glass, after treating that spore discharges and is attached to cover glass, at room temperature, the illumination of 1000-4000lux and every day 10-16 hour irradiation incubator in germinate and grow up, grow at last and be the highly branched thread sporophyte of difference.
