Abstract
Description
The present invention relates to a virtual contaminant comprising microalgae lipid as an active ingredient, and more particularly to a method for cultivating microalgae comprising culturing a microalgae, concentrating the microalgae to be cultured, and extracting lipids from the concentrated microalgae A method for producing microalgae lipids, a virtual pollutant containing microalgae lipid produced by the above method as an active ingredient, and a method for producing the same.
As a photoautotroph, microalgae are photosynthetic organisms that make the sun the sole source of energy and carbon dioxide as the only carbon source and have the advantage of higher growth rate than other photosynthetic organisms, especially terrestrial organisms. High productivity. Generally, microalgae exhibit a characteristic that the amount thereof is doubled within 24 hours.
Microalgae live in the marine environment and are the lowest in the marine ecosystem and are used primarily as food for fish fry. Microalgae Biomass is rich in nutrients such as protein, carbohydrates, vitamins and minerals and contains lipids that are essential for the growth of fish fry. In fact, many fish farms operate a micro-algae cultivation field around fish farms for use as rice for chewing.
In order to prepare for oil spill accidents, control training is being carried out globally by using virtual contaminants having properties similar to those of oil. On the other hand, virtual contaminants are floating, mobile oil-like substances that must float on the surface for at least 2 hours and should be easily identifiable. In addition, virtual contaminants, which are frequently used in a wide range of categories, should be characterized by low cost.
On the other hand, virtual contaminants are liquid virtual materials and solid virtual materials. In the past, substances such as popcorn, orange, and rice bran have been used, but they are known to have a bad influence on marine resources utilization. Research is underway to develop alternative liquid materials for liquids. On the other hand, U.S. Patent Nos. 7,528,097 and 7,691,908 disclose a technique for producing biodegradable non-emulsion-like crude oil derived from natural materials such as canola oil, cottonseed oil, soybean oil and sunflower oil in detail, Natural materials have a disadvantage in that the supply is not constant, and there is a problem that mass production is difficult. In addition, biodegradable non-emulsion-like crude oil derived from such a natural substance may be contrary to the Marine Environment Management Act.
In order to solve the above problems, the present invention relates to a virtual pollutant containing microalgae lipid as an active ingredient.
In order to achieve the above object, the present invention provides a virtual pollutant containing microalgae lipid as an active ingredient.
In addition, the microalgae lipid may be obtained by (a) culturing microalgae; (B) concentration of the cultured microalgae; And (c) extracting lipids from the concentrated microalgae.
In addition, the present invention provides a method for producing a virtual contaminant comprising microalgae lipid as an active ingredient.
The virtual contaminants containing the microalgae lipid as an active ingredient of the present invention can be recovered from microalgae capable of mass culture and production, and lipids having physical properties similar to those of crude oil or oil can be easily supplied and received. In addition, the present invention can use lipid components contained in microalgae for marine control training.
Hereinafter, the present invention will be described in detail.
The present invention provides a virtual contaminant comprising an algae lipid as an active ingredient.
The present invention also provides a method for producing a virtual contaminant comprising microalgae lipid as an active ingredient.
The microalgae are selected from strains which have a high lipid content and are capable of mass culture and production so as to meet the object of the present invention and are selected from the group consisting of Chlorella sp., Rhodotorula sp., Scenedesmus sp. two anri Ella (Duanliella sp.), nanno keulroriseu (Nannochloris sp.), bidul Pia (Biddulphia sp.), Kane Chitose Ross (Chaetoceros sp.), mono Douce (Monodus sp.), in Paris, Saturday keulroriseu (Parietochloris sp .), Emilia California (Emiliania sp.), isobutyl Cri sheath (Isochrysis sp.), L Pseudomonas (Phaeomonas sp.), glow predetermined mask matrix (Glossomastrix sp.), APA furnace kapsa (Aphanocapsa sp.), Spirulina (Spirulina such as Rhodotorula sp., Trichodesmium sp., Hemiselmis sp., Rhodomonas sp., Gymnodinium sp., etc., but preferably Rhodotorula sp. sp.) may be cultured, but the present invention is not limited thereto.
The microalgae lipids comprise (a) culturing microalgae; (B) concentration of the cultured microalgae; And (c) extracting lipids from the concentrated microalgae.
The step (a) may be a conventional microalgae cultivation step, but may include, but is not limited to, a raceway pond or a photobioreactor method. Carbon dioxide which is essential for photosynthesis such as photoauthotroph culture in the microalgae culture step can be supplied by a conventional method used in the art. On the other hand, a microalgae culture step can be performed by feeding a nutrient source necessary for microalgae growth such as nitrogen and phosphorus by using a heterotrophic culture method. In the step of culturing the microalgae, impurities or suspended substances may be additionally removed by filtration or coagulant.
The step (b) is a step of concentrating the microalgae cultured in step (a), wherein the concentration of the microalgae obtained by the step of culturing the microalgae is less than 1 g / L, , Flocculation, osmotic, or centrifugal separation may be used, but the present invention is not limited thereto.
The step (c) is a step of extracting lipids from the microalgae concentrated in step (b), and may be carried out using a physical method and / or a chemical method. Physical methods include disruption of microalgae cell walls using ultrasound waves such as ultrasonic waves or microwaves, selective extraction of lipid components, or decomposition of components such as proteins and carbohydrates constituting microalgae using pyrolysis Only components are selectively extracted. The chemical method may be performed by a solvent extraction method in which an organic solvent is used to selectively dissolve lipid components contained in microalgae. The organic solvent may be hexane, ether, chloroform, And a mixture thereof. Of these, hexane is preferably used. The solvent extraction method can be carried out by a conventional stirring extraction apparatus.
The step (c) may further include the step of applying pressure to the concentrated microalgae in the step (b), which may increase the efficiency of microalgae lipid extraction.
Meanwhile, the lipid may be extracted in the form of a fatty acid such as C18: 0, C18: 1, or C18: 2.
The present invention also provides a method for producing a virtual contaminant comprising microalgae lipid as an active ingredient.
The virtual contaminants containing the microalgae lipid as an active ingredient of the present invention can be used for marine control training in which the physical properties of lipids extracted from microalgae are similar to crude oil or oil.
Claims (2)
The lipid may be selected from the group consisting of: (a) microalgae culture; (B) concentration of the cultured microalgae; And (c) extracting lipids from the concentrated microalgae.
