Description

Liquid cell cultivates special inoculation frame
Technical field
The utility model relates to microorganism culturing, refers to that a kind of liquid cell cultivates special inoculation frame especially.
Background technology
Microbial inoculant is the elementary operation technology in microbiological research, all need microorganism to be forwarded in the substratum of another fresh sterilizing in microbiology test and fermentative production, make its growth and breeding by cultivation object difference and obtain meta-bolites, can adopt inclined plane inoculating, liquid inoculation etc., current inoculation not yet can realize automated operation.
Bacterial classification often adopts the mechanism of amplifying step by step to carry out spawn activity, adaptive enhancing during the fermentation, finally ferments fast and efficiently, produces and accumulate a large amount of object product in thalline or in fermented liquid.Amplify step by step and namely carry out the even multistage seed culture of one-level, secondary by a small amount of inclined-plane of preservation or liquid spawn with certain inoculum size (5-10% as volume ratio), to improve spawn activity, to adapt to fermentation condition.Amplify step by step and be applied in microorganism cells, microalgae cell, the pilot scale culture of zooblast and the prior fermentation experiment in laboratory, particularly liquid fermenting process.Therefore guarantee liquid seeds culture transferring process safety, fast and convenient operation is one of prerequisite of carrying out smoothly of fermenting.
Usually triangular flask is adopted when carrying out one-level or secondary seed cultivation in laboratory, for guaranteeing the homogeneity inoculating seed in each bottle of fresh liquid substratum, the method of many employings " one-to-many ", i.e. by one bottle of seed liquor (or cultivating the seed liquor after merging with a collection of), by certain inoculum size, with transfer pipet or pipettor, liquid seeds is evenly accessed in many bottles of fresh liquid substratum, even if in last access liquid fermentation medium, in laboratory be also one bottle to the operator scheme of many bottles.
The aseptic technique of seeded process is carried out usually in laboratory in Bechtop, carries out in factorial praluction at sterilisable chamber, and both all need to utilize ultraviolet to article surface sterilization 20-30 minute before use.Mention when telling about the ultimate principle of aseptic technique in " industrial microbiology experimental technique " (Tianjin science tech publishing house), miscellaneous bacteria in air easily falls with dust at air-flow hour and causes microbiological contamination, therefore in seeded process, the time of opening culture vessel is as far as possible short, mouth will tilt and should in the sterile field of flame zone (i.e. spirit lamp flame kernel radius 5 centimetres), and operational requirement is skilled accurately fast.In the seed transfer process of factorial praluction, as far as possible the principle of aseptic technique reduces the chance of seed bottle opening, can pressurize with should adopt negative pressure or the sterile air of pressure as far as possible.Therefore for the operation of this one-to-many, for avoiding from the beginning microbiological contamination the bottleneck of all triangular flasks should be tilted in operation, and the sterile field being placed in flame zone is interior, pulling out of bottle stopper of minimizing of trying one's best fills in number of times, ensures that skilled operation is accurately quick simultaneously.
The operation of this one-to-many, during by one man operation, need to grip seed liquor and fresh medium two bottles on the other hand, another hand is after the other bung off of flame, with liquid-transfering device, seed liquor sucking-off is reinjected in fresh culture, then the stopper lid crossing flame is returned two bottlenecks.Transfer second bottle time, same one hand holds same seed liquor and another bottle of fresh medium, repeats the same operation.Therefore, for seed liquor, whole seeded process needs repeatedly to pull out in aseptic operating platform to cover into bottle stopper, as for a bottled amount being 250 milliliters of triangular flasks of 100 milliliters, if accessing 10 with the inoculum size of 10% (volume ratio) bottledly has in 250 milliliters of next stage liquid mediums of 90 milliliters, so this bottle of seed liquor bottle needs repeatedly to pull out and covers into 10 bottle stoppers.Such operation not only have impact on the flowing of germ-free air flow in operator's console, easily causes the early stage microbiological contamination of liquid fermentation and culture because bringing miscellaneous bacteria into, and all needs to utilize flame to carry out sterilising treatment to two stoppers at every turn, extends the time of inoculation.For the personnel that inoculation experience is not enriched, in the other operation carrying out two bottles of flame, not only speed slowly and easily cause burning accident.Particularly often use in large-scale production for the large triangular flask of loading amount (triangular flask as 500 milliliters or 1 liter); ordinary person's one hand grips two simultaneously and has any problem, and can only stand upright in operator's console by triangular flask, pull out bottle stopper; after drawing seed liquor, then cover into bottle stopper.This operation, due to bottleneck directly on be exposed in air, one miscellaneous bacteria be the increase in air is directly mixed into the probability of seed liquor, in addition due to the limited space of Bechtop, or by the restriction of cover plate pull-out altitude, too increase the operation easier of pipettor in worktable (as transfer pipet).For the problems referred to above, the solution adopted is operated by two people more at present, a people holds seed bottle, all the time seed bottleneck is aimed at flame, another people holds fresh medium bottle and is responsible for sucking-off and the injection of seed liquor, so coordinates and the bottleneck of seed liquor can be kept to tilt and reduce microbiological contamination chance, also accelerate inoculation speed simultaneously, but consume manpower, and reduce inoculation efficiency.In large-scale production, transferred species or the inoculation that spreads cultivation carry out at sterilisable chamber; along with the increase of operator's quantity; also greatly add the chance of bringing miscellaneous bacteria into, therefore need a kind of inoculation of design utensil badly, it is very necessary for solving the single inoculation operation completing large loading amount triangular flask in large-scale production.
