Description
[technical field]
The present invention relates to little algae culturing engineering field, specifically a kind of gas push type photobioreactor of cultivating little algae.
[background technology]
Little algae can effectively utilize luminous energy, carbonic acid gas and inorganic salt, the biologically active substance of synthetic fat, protein, polysaccharide and multiple high added value.Along with the continuous intensification of the mankind to little algae understanding, develop and develop new and effective bioreactor and cultural method thereof, become an important component part of little algae biotechnology.
At present, little algae is cultivated and mainly contains open and closed two kinds of bioreactors.Open bioreactor mainly contains four types: on-swimmer's pool, circulatory pool, runway pond formula, pond.Wherein, the most typical, the most the most frequently used open pond culture systems is the runway pond reactor of Oswald (1969) design, and in fact such culture systems is exactly thousands of square metres of floor spaces, and the nutrient solution degree of depth is the shallow annular pond about 20 centimetres; With the natural light is light source and thermal source, relies on the rotation of paddle wheel (paddle wheel) or pivot arm (rotating arm), makes nutrient solution mix in the pond, circulate, and prevents the efficiency of light energy utilization of frond precipitation and raising frond cell.Though it is simple, with low cost, easy and simple to handle that open bioreactor makes up, there are shortcomings such as vulnerable to pollution, culture condition instability in it, can only be used for little algae cultivation that minorities such as spirulina, chlorella and salt algae can tolerate extreme environment.And the closed reactor culture condition is stable, but high-density culture is easily carried out in aseptic technique, has become developing direction from now on.Compare with open bioreactor, closed photo bioreactor has the following advantages: 1. pollution-free, can realize single kind, purebred cultivation; 2. culture condition is easy to control; 3. the culture density height is easily gathered in the crops; 4. the light autotrophy that is suitable for all little algaes is cultivated, and is particularly suitable for the production of little algae meta-bolites; 5. the ratio of higher illuminating area and volume of culture is arranged, and luminous energy and carbonic acid gas utilization ratio are higher.Therefore, development of closed photo bioreactor at home and abroad in recent years and development and use are very fast, and some has realized the high-density commercialization cultivation of little algae.At present closed photo bioreactor has: duct type, flat, column air lift type, stirred-tank fermenter, vertical Pig, floating bag film etc.
Existing closed photo bioreactor causes easily more or less that dissolved oxygen is accumulated, variety of issues such as under-supply, the flow blind angle of carbonic acid gas, equipment manufacturing cost costliness when the sticking wall of frond, high-density culture, except pipeline reactor, substantially all be in laboratory scale, volume is no more than 1 cubic meter.Though and the annual output that the duct type bioreactor is reported has at present reached up to a hundred tons of algae powder, the cost of this equipment and maintenance cost are very high, are difficult to popularize.
In fact, no matter which kind of design form bioreactor adopts, and develops the closed photo bioreactor of a kind of successful little algae of cultivation, all should follow following principle: (1) high illumination surface to volume ratio; (2) higher gas exchange efficiency; (3) Recycle design of Shi Heing; (4) improve route of transmission, distribution and the quality of light; (5) prevent the accumulation of harmful secondary metabolite; (6) more easily realize the optimal control of culture condition; (7) reduce manufacturing cost as far as possible.Can predict, the sort of cost is low, volume big, the more rational closed photo bioreactor of design should be the emphasis and the developing direction of exploitation.
