Description

Closed the holding concurrently of a kind of micro-algae supported culture method and culture systems thereof
Technical field
The present invention relates to micro-algae culture technique, be specifically related to closed the holding concurrently of a kind of micro-algae and support culture method and culture systems thereof.
Background technology
Micro-algae (microalgae) is the unicellular algae existing with individual, chain or group form of a large class microcosmic, and size is not from several microns to hundreds of micron etc.Micro-algae is of a great variety, and nearly 200000-800000 kind, wherein has the kind more than 35000 that has recording according to estimates.Micro-algae is divided into the micro-algae of autotrophy, heterotrophic microalgae and holds concurrently and support micro-algae.From the sixties in 20th century, since first Japan start to carry out the extensive both culturing microalgae of commercialization, people can realize micro-algae at multiple fields such as protective foods, medical material, beauty treatment, feeds and commercially produce so far.
The cultivation of micro-algae large-scale autotrophy is mainly adopted in two ways: open microalgae cultivation system and sealed microalgae cultivating system.Open cultivation system is exactly that the outdoor natural sunlight that utilizes carries out both culturing microalgae, has the advantages such as expansion scale ratio is easier to, cost is lower.But open cultivation system is easily subject to the impact of external environment, as intensity of illumination, light application time, temperature and weather; Also be easily subject to the pollution of other algae kinds, bacterium and pathogenic microorganism.Sealed microalgae cultivating system refers to and utilizes substratum in airtight container, to carry out both culturing microalgae.Sealed microalgae cultivating system can be divided into fermentor tank, culture bag, plate smooth biochemical reactor and cast light biochemical reactor; Micro-algae large-scale heterotrophism cultivation is to utilize industrial fermentation method heterotrophism to cultivate micro-algae, can save space, improves output, avoids the pollution of assorted algae and bacterium, and culture condition easily controls, and is the development trend of micro-algae large-scale industrialized production.Part produce oil algae can make its training method transfer heterotrophism to by autotrophy by metabolic regulation, owing to not relying on illumination, does not also consume CO 2, can utilize common fermentor device to cultivate, but will strictly keep sterile state in culturing process.
The double foster cultivation of micro-algae can utilize organism, carbon source, carries out photosynthesis simultaneously.Micro-algae is held concurrently and supports in culturing process, and photoautotrophy and chemoheterotrophy are synchronous and relatively independent processes.Illumination has impact to two pathways metabolisms, but influence degree is different.
Available Microalgae refer to those batch production productions or application prospect, can be by a large amount of kinds of cultivating of biotechnology, in its cell, contained certain or some composition can be utilized by people.At present, Available Microalgae has a few class fronds such as spirulina, chlorella, Dunaliella salina, haematococcus pulvialis.Wherein, the fat content of chlorella is high, can be used as raw material prepared by the renewable energy resources.Chlorella can utilize at sun power and have function to carry out Fast Growth and accumulation grease.(2013) results of study such as Li Tingting show: adopt different training methods, carry out biomass and the lipid production experiment of chlorella.Under the condition of supporting of holding concurrently, can obtain and compare independent light autotrophy or independent heterotrophism, better growth performance, chlorella lipid content also increases considerably.
At present, the cultivation of chlorella large-scale commercial is mainly to carry out in bioreactor, and its floor space is large, the production cycle long, stand density is lower etc., has in a disguised form increased production cost, has limited extensive chlorella cultivation development.Finding a kind of high-density, chlorella cultural method cheaply, is important to promoting chlorella aquaculture industry development pole.
Summary of the invention
The object of this invention is to provide closed the holding concurrently of a kind of micro-algae and support culture method, adopt closed cultured continuously mode, in culturing process, with constant speed, emit the fresh algae liquid of part and process purification, another part is as the cultivation that refluxes of algae kind, supplement corresponding substratum and sterilized water simultaneously and make it to realize the closed cultured continuously of micro-algae, improve the productive rate of micro-algae.
