Description
Technical field
The invention belongs to biotechnology and field of biological energy source, and in particular to a kind of method that utilization single needle algae produces microalgae grease.
Background technology
Due to the exhaustion of world petroleum resource and since price is gradually high, environmental issue is increasingly serious, and Global climate change causes a series of impact, 20 century 70s, the development of many national pay attention to day by day bioenergies and biological-based chemicals.In numerous biomass energies and biomass chemicals, microalgae has obtained increasing concern by the advantage of its " grain not being striven with people, ground is not striven with grain ".
Algae is one of biology of most original, and distribution is very wide, and most of algae are lived in water, its simple structure, with photosynthetic efficiency height, the short and fireballing feature of growth cycle.Algae includes microalgae（Unicellular eukaryote）, large-scale algae（Sargassum）And cyanobacteria（Blue-green alge）.Different algal species can pass through photosynthesis by CO2O is converted into water2And larger molecular organicses, such as carbohydrate and oils and fatss.The culture of microalgae does not strive water with striving with crops, it is possible to use the nutrition such as N, P in waste water, so as to reduce the eutrophication of water body, saving water resource and nutritive salt cost.Therefore, using non-grain and reproducible microalgae is the raw material production energy and chemicals, compared with other biomass, to a certain extent can reduces cost, while also the exploitation for microalgae downstream product provides a new approach.
Single needle algae is one kind of chlorella, is irregular spindle, and the single needle algae having now been found that is only used for accumulating oils and fatss.CN103540533A discloses a kind of acquisition and application of oil-producing single needle algae LB59, separates from wild environment and obtains, is resistant to high concentration sodium bicarbonate, it is easy to carry out open culture, and rich in oils and fatss, fat content can reach the 30.2% of dry cell weight.CN103555584A discloses a kind of acquisition and application of oil-producing single needle algae LB50, is resistant to high concentration sodium bicarbonate, and fat content can reach the 30.4% of dry cell weight.CN104073437A discloses a kind of single needle algae C29, and its fast growth, lipid-producing are high, is the strain excellent for producing biodiesel；The invention additionally provides a kind of open foster method of single needle algae, and the method adopts defined medium culture, the more conducively growth of single needle algae C29 and the accumulation of oils and fatss.CN104611228A discloses a kind of rich grease-contained single needle algae（Monoraphidium
sp）SS-B1 and its culture application, deposit number is CGMCCNo.7479, and the algae strain is resistant to the CO of high concentration2And SO2, it is possible to use containing CO2And SO2Waste gas or flue gas carry out illumination autophyting growth and obtain rich grease-contained biomass, carbon sequestration efficiency high, cell total lipid content account for more than the 40% of dry cell weight, can carry out the production of biodiesel.
But, above-mentioned single needle algae is only used for producing oils and fatss, and product is single, and range of application is narrow.There is presently no discovery and not only can produce starch but also can be with the single needle algae of Lipid-producing.
The content of the invention
For the deficiencies in the prior art, the present invention provides a kind of method that utilization single needle algae produces microalgae grease.The inventive method contributes to the propagation and oil and fat accumulation of frustule, can obtain the frustule of high fat content, the features such as with process is simple, low cost, high output.
