Description
Technical field
The present invention relates to technical field of cell culture, and in particular to a kind of a kind of plant cell of suitable large-scale production,
Organ liquid culturing apparatus.
Background technology
With world rapid economic development, the ample supply of the fossil resources such as existing oil coal becomes to hold
It is continuous, it is difficult to support the advanced developing goal of human society.Human social development will be from dependent on hydrocarbons such as fossil fuels
Resource is changed into the carbon aquation that solar continuous synthesis can be utilized by starch, cellulose, polysaccharide, plant and microbial grease etc.
Close goods and materials source.The transformation of this energy and resource structures will be that biotechnology and its industry development bring very big opportunities and challenges.
For plant available resources, China is one of the country that resources of medicinal plant is most abundant in the world, with plant
A large amount of uses of medicine, the excavation of medicinal plant and using the speed of growth considerably beyond plant, resources of medicinal plant is increasingly withered
It exhausts.And traditional medicinal plant field production is influenced by " favourable climate and geographical position ", and output and quality fluctuation is big, and pesticide residual contamination is asked
Topic is also than more serious.
Therefore, people are by means of various biosystems, using carbohydrate come all needed for large-scale production modern society
Such as plant cell, tissue and the various useful components of organ.And the biochemical reaction that biosystem carries out substance conversion is in biology
It is carried out in the microhabitat of this relative closure of reactor.Bioreactor provides controllable for the biochemical reaction of biosystem
Environmental condition promotes biomass conversion process efficiently to carry out, for example, temperature, pH, dissolved oxygen, mixing, shearing, feed supplement etc..It passes
System bioreactor generally comprises suspension culture systems reactor and Immobilized culture system response device.The former includes mainly stirring
Formula reactor, airlift reactor；The latter includes mainly membrane reactor, packed bed reactor.
The bioreactor of culture plant cell, tissue and organ has arrived the stage of industrialized production at present.Example
Such as, with airlift bioreactor culture Catharanthus Roseus Cell production serfin [A.H.Scragg et al., Enzyme Microb
Technol, 1987,9：619]；South Korea S.H.Son et al. to yew cell carry out reactor large-scale culture, using from
Airlift reactor [S.H.Son et al., the Plant Cell Reports (2000) 19 of 100L to 500L：628-633]；
After several years, Kee-Yoeup Paek carry out large-scale culture to ginseng adventitious root using spherical bubbling style reactor and obtain with very
Ginsenoside [Kee-Yoeup Paek etal., Adv the Biochem Engin/Biotechnol (2009) of strong pharmacological activity
113：151-176], obtain the ginseng adventitious root etc. compared with height increament.Meiyan Inst. of Biological Engineering, Meixian County is followed using gas
Ring type bioreactor production yew cell has been also up to level [the gas circulating type plant cell reactor of 500L
CN2510499Y].U.S. Phyton, Inc have been reached using stirring type bioreactor culture yew cell production taxol
To 7 tons of scale.South Korea SamyangGenex is also producing taxol using stirred-tank fermenter culture yew cell.
Stirring reactor is one of most commonly used reactor of industrial applications, due to plant cell have volume compared with
Greatly, cell wall is more crisp and has the characteristics that big vacuole, and plant cell is very sensitive to shearing force, sensibility by cell kind
The many factors such as class, state, shearforce tolerance, the structure of shear rate and reactor itself determine.Currently, the approach solved
Typically from cell line, the high yield system of anti-shearing force is screened or by cell engineering and genetic engineering means to existing
Cell line is transformed, and establishes the strain of anti-shearing force；Structure of reactor is transformed on this basis, makes it have the flow field of mitigation
And good mixed performance.But still it has the following problems：1) currently used reactor is all integrally fixed at a certain position, inoculation
When need outdoor inoculation, while secondary opening tank body is needed when feed supplement, microbiological contamination probability can obviously increase, and microbiological contamination problem is plant
It is most difficult to solve the problems, such as in tissue cultures；2) tank body that reactor is mostly made using stainless steel as material, therefore all needed when making
It is arranged one and arrives multiple transparent viewing ports.Many dead angles are still had in actual use to be difficult to observe by；3) stirring-type biology
Reactor opereating specification is big, realizes the also more of industrialization production, but the shearing force generated in whipping process is larger, is easy to planting
Object in vitro tissue causes to damage, and energy consumption is larger；4) since mechanical stirring device cannot sterilize, the type equipment is gone out
It needs steam-out (SO) to sterilize when bacterium, pays particular attention to the danger and complexity of high steam, and steam sterilizing goes out
Bacterium can cause culture volume to increase simultaneously, and it is unstable to accelerate, also result in substance volatile in culture medium and
Gasification temperature is discharged less than the substance of water with steam；
In contrast, airlift reactor and bubbling style reactor shearing force are smaller, generally believe bubbling both at home and abroad at present
Formula reactor is a kind of widely applicable bioreactor, and this kind of reactor is structurally characterized in that bubble rises along liquid phase, with
Agitation liquid is to improve mass transfer rate while liquid phase contact is reacted.However the advantages of being in theory above, really
Realize that the very few of industrialization, most of bubbling style reactors only remove the mixing plant of stirring reactor, because
This its use scope is far below stirred-tank fermenter, and traditional bubbling style reactor is returned due to being susceptible to without agitating device
It is mixed serious, phenomena such as bubble is also easy to produce coalescence, and foam can carry some 2 volatile materials of CO secretly, while in order to which culture is molten
The demand of oxygen needs largely to be passed through gas, and intercourse meeting leads to a large amount of evaporations of culture medium, is generated not to the growth of plant cell
Good influence, and it is less efficient, although can weaken this influence by the way that antifoaming agent is added, antifoaming agent is added can be thin to plant
Born of the same parents, the growth of tissue and organ and the accumulation of secondary metabolite generate bad.Simultaneously because air inlet is to dissolved oxygen in culture medium
Incrementss are insufficient, therefore culture medium dissolved oxygen problem is than more serious, while the excessive material for causing some to need long-term cultivation of ventilatory capacity
Material, later stage can have to terminate culture because of the evaporation of culture medium.Many equipment of the type and stirring type bioreactor one
Sample needs to sterilize using external high steam, increases danger and complexity when operation, and culture medium holds when sterilizing
The unstability of amount.
The reactor of any of the above type is based on amplification scale, due to needing to amplify step by step, centre any one
Go wrong such as microbiological contamination, browning of step can lead to the failure finally cultivated, and mini-reactor simple to operation can be with
Problem above is solved well.
In small-sized biological reactor simple to operation, that has been applied at present has GE Healthcare Wave
The wave bioreactor of Products Group productions, WAVE wave bioreactor cultures volume range is flexible, operates
Simply, control precision is reliable, easy to technique amplification.But wave wave reactors use composite material, are used as fermentation tank
Polybag is combined by three-layer plastic, internal layer LDPE, and centre is EVOH, and outermost layer is EVA materials, cannot be gone out into horizontal high voltage
Bacterium needs that culture bag is first needed irradiation sterilization when in use, and then culture medium pours into after individually sterilizing in culture bag, and centre is such as
Fruit needs feed supplement to need to reopen culture bag and operated, and adventitious root class culture is difficult to cultivate in wave reactors,
And culture bag can not reuse, therefore environmental pollution can be caused, in addition, the oxygen of wave culture bag culture mediums is to pass through
Liquid surface gas exchanges carry out, therefore dissolved oxygen is easy deficiency in culture medium, and culture late growth will be severely limited, most
Culture quality is caused to go wrong with yield eventually.
Complicated for operation to solve equipment costliness in the prior art, culture medium evaporation capacity is big in incubation, incubation
