技术领域 FIELD
本发明涉及一种可调控的全天候封闭式大规模运行系统光生物反应器培养和促进雨生红球藻生长增殖及提高种群密度和调控细胞内次生代谢产物虾青素合成和积累的方法。 The present invention relates to a control system to run large-scale weather enclosed photobioreactor foster and promote pluvialis algae proliferation and increase population density and secondary metabolites in the regulation of cell astaxanthin synthesis and accumulation methods.
背景技术 BACKGROUND
雨生红球藻(Haematococcus pluvialis)是一种单细胞绿藻,细胞呈椭圆形或卵形,大小从5微米左右到20-30微米不等,有时甚至更大些;有两条等长鞭毛,鞭毛的摆动推动细胞自由游动;细胞壁和原生质间具空隙,其间充满胶状物质,细胞壁和原生质体间有细胞质连丝相连,营养繁殖为细胞分裂,形成2、4、8、16甚至更多个子细胞,无性生殖在环境不良时形成胶群体或厚壁孢子。 Pluvialis algae (Haematococcus pluvialis) is a single-cell green algae, elliptical or oval cell size from about 5 microns to 20-30 micron range, sometimes even bigger; there are two equal-length flagella flagellum swing to promote free-swimming cells; a gap between the wall and protoplasm, which is fraught with a gelatinous substance, between the cytoplasm of the cell wall and protoplast have even wire connected vegetative propagation of cell division, the formation of 2,4,8,16 even more multiple sub-cells, the formation of asexual spores thick glue groups or bad environment. 处于生长增殖阶段的雨生红球藻呈绿色;当环境条件的改变对其生长不利时,如在缺乏氮、磷和双价离子镁或在强光照射条件下,雨生红球藻细胞的生长将趋于缓慢并使运动细胞失去鞭毛,形成胶群体或厚壁孢子,同时,促进细胞内次生代谢产物合成,主要是虾青素的大量积累,使雨生红球藻细胞的颜色迅速形成砖红色。 In the proliferation phase pluvialis algae green; when changes in environmental conditions detrimental to their growth when, as in the absence of nitrogen, phosphorus and magnesium bivalent ions or in bright light conditions, pluvialis algal cells will tend to slow the growth and movement of cells lose their flagella, the formation of groups or thick-walled spores gum at the same time, promote the intracellular synthesis of secondary metabolites, mainly massive accumulation of astaxanthin, so pluvialis algal cells rapidly colors the formation of red brick. 影响雨生红球藻的生理、生物量、产量和细胞内次生代谢产物成分和生成量,主要涉及藻的品种和良好的培养条件(如环境的净化程度、温度、光照、溶解氧、营养液组成、流体切变力等)。 Pluvialis algae affect physiology, biomass, yield and generate the amount of intracellular components and secondary metabolites, mainly related to algal species and good culture conditions (such as the degree of purification of the environment, temperature, light, dissolved oxygen, nutrients fluid composition, fluid shear force, etc.). 通过物理或化学以至基因工程及遗传工程手段改造现有藻种获得优良工程菌株,提高藻种的光饱和值、抗光抑制,以及抗逆、抗污染能力,可以获得耐高温、细胞增殖快和虾青素积累能力强的藻种。 By physical or chemical transformation as well as genetic engineering and genetic engineering to get good engineering existing algae strains, increase light saturation value of algae, anti-light suppression, as well as resilience, anti-pollution, you can get high temperature, rapid cell proliferation and astaxanthin accumulation ability of the algae. 有研究表明,经过优化的光生物反应器及良好的培养条件,可促使雨生红球藻中虾青素的含量高达细胞干重的4-5%,而采用细菌或酵母菌等培养生成虾青素的含量最高不足细胞干重的0.8%。 Studies have shown that after a photobioreactor and good optimization of culture conditions, can contribute to the content of the rain pluvialis astaxanthin up to 4-5% of the dry weight of the cells, and the use of bacteria or yeast, such as generating shrimp culture astaxanthin content of the highest cell dry weight of less than 0.8%.
目前,阻碍雨生红球藻大规模生产的主要因素是生物污染和雨生红球藻培养过程种群密度低使单位面积产量低所导致的高成本。 The main factors that currently hinder pluvialis algae bio mass production of pollution and population density pluvialis algal culture process, low cost and low yield per unit area so caused. 小规模由管道式光生物反应器或小型固定化系统组成的生物反应器或气升式生物反应器进行培养的雨生红球藻,存在的缺陷是管道壁易被藻细胞粘连遮蔽导致培养期间透光性下降及清洗困难,虽然已采用不同类型的桨叶轮搅拌混合,以尽量降低藻细胞之间的遮蔽作用及提高光照的利用,但只适应实验室的小规模试验。 Bioreactor or airlift bioreactor small scale by pipeline or small photobioreactor system consisting of immobilized cultured rain pluvialis, defects during the pipe wall is easily obscured cause algal cell adhesion culture translucent drop and difficult to clean, although the use of different types of mixing paddle wheel to minimize the shielding effect between the algal cells and improve the utilization of light, but only accommodate small scale laboratory tests.

封闭式大规模运行系统中光生物反应器的设计对于提供可调控的环境条件促进雨生红球藻迅速生长增殖和提高种群密度及促进细胞内次生代谢产物虾青素的合成和积累至关重要。 Optical design of a closed bioreactor system for large-scale operation to provide adjustable environmental conditions promote rapid pluvialis algae proliferation and increasing population density and promote intracellular secondary metabolites astaxanthin synthesis and accumulation to close important. 培养雨生红球藻由于非生物因素的变量太多,如生物污染、光照强度、溶解氧、温度和营养液组成等多种因子的影响和应变环境促进细胞内目标产物的合成和积累而变得非常复杂。 Pluvialis algae culture because too many variables abiotic factors, such as environmental impact and strain various factors of biological contamination, light intensity, dissolved oxygen, temperature and composition of the nutrient solution to promote the synthesis and accumulation of intracellular target product becomes very complex. 光照是雨生红球藻生长的重要因素。 Light is an important factor pluvialis algae. 最适于雨生红球藻生长增殖的光照度为中等强度光照1000-1600勒克斯;加大光照强度在1900-3200勒克斯,可促进雨生红球藻细胞内次生代谢生物虾青素合成和积累;大于3500勒克斯的光照强度将抑制雨生红球藻的生长,分裂的细胞也由营养生长转为休眠状态。 The most suitable pluvialis algae growth and proliferation of moderate intensity illumination lux illumination 1000-1600; 1900-3200 lux light intensity increased, can promote within pluvialis algal secondary metabolites biological astaxanthin synthesis and accumulation ; greater than 3500 lux light intensity will inhibit pluvialis algae growth, division of cells into a dormant state by vegetative growth. 昼夜连续光照有利于雨生红球藻的生长增殖并明显提高细胞体积产率。 Continuous day and night illumination is conducive pluvialis algae proliferation and cell volume significantly increased yield. 培养过程光照不足及藻细胞相互之间的遮蔽作用,将导致藻细胞生长受到抑制而增加了其他生物污染的机会。 Insufficient light shielding effect of the training process and algal cells between them, will lead to algal cell growth inhibition and increases the chance of the other biological contamination. 在室外人工培养微藻采用的桨叶轮搅拌的浅水道光生物反应器,构造上只接受正面光的光照,对光线的充分利用及光照的调控受到局限,特别是昼夜和阴晴天与正常日光光照强度差别大的影响成为大规模培养雨生红球藻及调控细胞内次生代谢产物虾青素的合成和积累的关键性技术难题。 In the outdoor artificial cultivation of microalgae used in stir paddle wheel shallow dynasty bioreactor only accept positive light on the structure of light, to make full use of light regulation and lighting has been limited, especially in day and night and confront with normal daylight illumination Large differences affect large-scale cultivation has become pluvialis algae and secondary metabolites in the regulation of cell astaxanthin synthesis and accumulation of key technical problems.
通过改造并优化浅水道光生物反应器系统成为封闭式光生物反应器,在主体反应器的底部及四周和封盖采用透光材料提高光生物反应器内整体光照强度,改善整体的培养条件为可调控的高净化度的环境条件,利用日光光照并外置可调控的人工光源照射使藻细胞昼夜能均匀地接受到中等以上强度光照,对光能利用率较高,既可促进雨生红球藻细胞生长增殖,又能调控雨生红球藻细胞内次生代谢产物虾青素的合成和积累,雨生红球藻细胞体积产量高达4-6g/L以上,其中虾青素含量可高达细胞干重的4-5%以上,同时又能克服开放式大规模运行系统光生物反应器运转期间昼夜和阴晴天的影响及其他杂藻和生物沾污以及大气污染。 The light through the transformation and optimization shallow bioreactor system becomes closed photo bioreactor, and around the body at the bottom of the reactor using light-transmitting material and the closure within the photobioreactor improve overall light intensity, improve the overall culture conditions to be regulation of the environmental conditions of high degree of purification, illumination and external use of daylight and artificial light irradiation can be regulated so that the circadian algal cells uniformly received above average light intensity of high energy efficiency, can promote pluvialis algal cell growth and proliferation, but also in the regulation of cell pluvialis algal secondary metabolites astaxanthin synthesis and accumulation pluvialis algal cell volume output of up to 4-6g / L or more, which can be as high astaxanthin content cell dry weight of more than 4-5%, while the open during a large-scale operation to overcome the photobioreactor system operation and confront affect circadian day and other miscellaneous algae and bio-contamination and air pollution. 由于主体反应器封盖部分透光材料更换方便,使主体反应器整体清洗更加便利快捷,有利于实现由计算机控制长期半连续化生产。 Because the main part of the reactor lid translucent material easy to replace, so the main reactor overall cleaning more convenient and efficient, is conducive to long-term by a computer-controlled semi-continuous production. 因此,建立可调控的全天候封闭式大规模运行系统光生物反应器比浅水道光生物反应器培养和促进雨生红球藻细胞生长增殖及提高种群密度和调控细胞内次生代谢产物虾青素合成和积累更具优越性。 Therefore, the establishment of large-scale adjustable-weather running a closed photobioreactor system than the shallow dynasty bioreactor culture and promote pluvialis algal cell proliferation and increase population density and secondary metabolites in the regulation of cell astaxanthin synthesis and accumulate more advantages.
