Description
Technical field
The utility model relates to biological technical field, more specifically relates to a kind of airlift photobioreactor of Haematocoocus Pluvialls high-density culture, and this reactor is applied to the high-density culture of Haematocoocus Pluvialls and the cumulative process of astaxanthin.
Background technology
Haematocoocus Pluvialls (Haomatococcus pluvialis) is a kind of unicellular little algae, belongs to Chlorophyta on classification position, volvocales, haematococcus pulvialis section, haematococcus.It can accumulate astaxanthin in a large number in the specified phase of growth, is a kind of little algae that the exploitation future is arranged very much.As the little algae of economy, it has following advantage: 1) economic worth height, and according to the price of present world market, the price of 1 kilogram of dry algae powder is greatly about more than 20 dollars; 2) aquaculture cost is cheap, and what need only is a small amount of nutritive salt and certain temperature light condition; 3) as algae, haematococcus pulvialis is cultured the problem of environmental pollution that does not exist spirulina and the discarded liquid discharging of salt algae to bring.
The Haematocoocus Pluvialls vast market prospect has also caused international common concern, the technology of overseas utilization Haematocoocus Pluvialls production at present and extraction natural astaxanthin has obtained tremendous development, and the existing company of Sweden adopts artificial source's irradiates light bio-reactor to produce.The Aquasearch company of the U.S. carries out the algae cultivation in computer-controlled outdoor closed photobioreactor (AGM), cyanotech company then adopts " platform " formula bioreactor of sealing to cultivate.But at present certain distance is also arranged very much between the research of this algae and the commercialization production, mainly have following several respects problem in the production: (1) Haematocoocus Pluvialls is to the environmental change sensitivity, exponential phase of growth is short, the ability that opposing bacterium and protozoon pollute is relatively poor, to lose fecundity under the extreme environment, be difficult for set up stable, production technology system efficiently; (2) culture cycle is long, productive rate is low, poor continuity, and mass mortality in the process of coercing, and is unfavorable for large scale culturing.(3) cultivate in Da Chi, its efficiency of light energy utilization is restricted, and the production efficiency in this restriction astaxanthin accumulation stage has also increased production cost.Above problem has hindered the exploitation of this algae, greatly reduces its commodity value.For this reason, people seek the ecological regulation and control technology of cell high-density culturing condition and astaxanthin accumulation just energetically.
