藻类的实验室培养

微藻的实验室培养学生:林晓生学号:2120180414导师:杨缜教授一、藻类的概述藻类是原生生物界一类真核生物(有些也为原核生物,如蓝藻门的藻类)。
主要水生,无维管束,能进行光合作用。
藻类植物共约为2100属,27000种。
根据所含色素、细胞构造、生殖方法和生殖器官构造的不同,分为绿藻门、裸藻门、轮藻门、金藻门、黄藻门、硅藻门、甲藻门、蓝藻门、褐藻门和红藻门。
色素的颜色划分,藻可分为3类:绿藻、褐藻和红藻。
由于单胞藻具有利用太阳光能效率高、营养丰富、生长繁殖迅速、对环境的适应性强和容易培养等重要特性,因而受到重视。
微藻是一类在陆地、海洋分布广泛,营养丰富、光合利用度高的自养植物,细胞代谢产生的多糖、蛋白质、色素等,使其在食品、医药、基因工程、液体燃料等领域具有很好的开发前景。
二、微藻的营养模式和生长模式(二)、微藻的生长模式藻类在培养过程中,生长繁殖的速度,出现一定的起伏,这种生长模式可划分为五个时期(延缓期、指数生长期、相对生长下降期、静止期、死亡期)。
三、培养按培养的场所分室内培养和室外培养1)按培养基的形态分固体培养和液体培养2)按培养的纯度分纯种培养和单种培养3)按藻液的流动情况分静止培养和循环流动水培养4)按气体交换情况分充气培养和不充气培养5)按藻液与外界接触程度分封闭式培养和开放式培养6)按培养规模和目的分小型培养、中继培养和大量培养方式简单介绍其中的四种方式:(1)纯培养和单种培养纯培养(axenic culture):是无菌培养,指排除了包括细菌在内的一切生物的条件下进行的培养。
纯培养操作要求十分严格,要求有无菌室、超净台等设备,容器、工具、培养液等均须彻底灭菌。
培养成功率很高,是进行科学研究不可缺少的技术。
单种培养(single-species culture):指区别于纯培养的不排除细菌存在的培养(可以是生产性的,也可以是非生产性的)(2)封闭式培养和开放式培养封闭式培养(closed culture):指把培养液密封在透明的容器中,与外界空气隔离,暴露在阳光中,CO2完全采用人工供给的方法。

Bring total volume to 1 L with Pasteurized Seawater.1 900 mL2 NaCl (Fisher S271-500)23 g/L 393.8 mM3 MgCl2·6H2O(Fisher M 33)5 g/L 24.6 mM4 Na2SO4 (Sigma S6264)4 g/L 28.2 mMa)Pasteurized SeawaterDirectionsMost salt-water media used by UTEX includes natural seawater collected off-shore from Port Aransas, Texas in the Gulf of Mexico. Seawater having a salinity of at least 30 ppt is collected and pre-filtered, then stored undisturbed within polyethylene carboys at ambient temperature.Seawater is diluted to 30 ppt with double distilled water immediately prior topasteurization. A three-liter batch of seawater at 30 ppt in a 4-liter Erlenmeyer flask is covered with a small inverted glass petri plate and an inverted 250-ml beaker, then "pasteurized" in a steamer for 45 minutes. The pasteurized content of the flask is allowed to cool and left undisturbed at ambient temperature for approximately 24 hr. It is then again steam-pasteurized for 45 min., as on the previous day. After the flask cools the second time, the inverted-petri-plate lid is sealed in place with Parafilm and the flask is stored at refrigerator temperature until it is used to prepare culture medium. This pasteurized seawater may used immediately or may be stored for several months prior to use.Procedure:In various laboratories marine algae are cultured in media prepared from "pasteurized" seawater that is assumed to be heated to exactly 73 degrees C. The procedure described here heats 3-L batches of seawater to over 95 degrees C for two consecutive days, although it does not reach boiling temperature.This procedure generally does not cause precipitation of seawater, although excessive agitation of flasks, the use of scratched or etched flasks, or pasteurization of seawater at higher salinity may result in salt precipitation during heating.Pasteurized seawater prepared as described above appears to be nearly sterile, although it is not used to culture axenic UTEX cultures without further heating in agar. Liquid unialgal cultures grown in media prepared from seawater that has been pasteurized by this method can be sub-cultured for many years without the introduction of invasive contamination.2) P-IV Metal SolutionDirectionsFor 1 L TotalNote final concentration listed is for the stock solution.1.To approximately 950 mL of dH2O, add the nutrients in the order listed while stirring continuously.Note: The Na2EDTA should be fully dissolved before adding other components.2.

The soil should be a loam, with a mixture of particle sizes(sand, silt, clay).2. It should contain a moderate amount (15 - 20%) of very-well-decomposed organic matter.3. It must not contain pesticides, especially herbicides.4. It should be soil that has been aged (preferably for 6 monthsor more) under moist conditions and not, for example, freshpotting soil, soil that contains fresh manure, or soil to which acommercial fertilizer was recently applied.5. A slightly acidic soil derived from granite or other igneousrock is preferable to soil obtained from calcareous soils. Calcium carbonate can be added to the soilwater medium when it isprepared if a slightly alkaline medium is required.6. Particulate matter in the soil such as gravel, Perlite, orvermiculite are not necessarily damaging but can be ofconsiderable nuisance when wishing to quantitate the amount ofsoil used in the medium or when handling algae that arephysically associated with the soil. Particulate organic matter,such as compost that is only partially degraded, should beavoided altogether.4) Vitamin B12DirectionsFor 200 mL Total1. Prepare 200 mL of HEPES buffer (50 mM).2.

微藻工厂化培养经验分享(附单胞藻的培养配方)

微藻工厂化培养经验分享(附单胞藻的培养配方)在主要运用于大棚生物饵料方面 一定地点建立车间、浓缩之后近距离管道运输到养殖区域 、提取色素添加在饲料中,至于土塘泼洒,如何控制量、增氧和开口饵料这方面正在摸索,需要大家一起总结出经验。
今天我跟大家主要跟大家分享一下藻种的工厂化规模化培育。
群里面应该很多人都培育过藻,大家都知道藻种的培育分为一级、二级、三级培养,今天我是简单从一级、二级、三级培养过程可能中遇到的问题、日常管理、接种、藻种营养配方这些方面做一下简单的交流。
养殖品种的需求量也不同。
所以培养条件、营养盐配方等各有不同。
今天我主要是以金藻为例,引申出其他藻种的营养配方,让大家学习一下其中的相似点。
国内大部分水产育苗企业,在育苗生产中都是自备微藻养殖设施,自行生产各类饵料用微藻。
但是一般育苗场都普遍缺乏相应的专业技术力量,只能利用各自的藻池和天然水体粗放培养,在饵料微藻种质、生产技术和应用方法上都各自为正,导致微藻种质混乱、供应不稳定、营养成分不平衡、饵料效价低、缺乏多品种集约化生产应用技术;同时,受限于微藻高密度养殖、采收技术和浓缩液保藏技术的限制,国内几乎没有统一的、专业化的饵料微藻质量标准和集中供应点。
所以工厂化育苗需要及时的补充藻种,开口饵料非常重要。
首先从工艺流程上来说一级培养:主要用于保种,主要用的仪器是锥形瓶,其能够完全消毒,所以应用在保种上面特别多。
二级培养:主要是用塑料白桶(聚丙烯材料),生产上也用 的饮水桶,但是瓶口小,操作不方便,消毒也不彻底;而用氧气袋又易破裂。
在南方经常可以见到用玻璃制作的大型鱼缸和氧气袋。
回复举报 来自 客户端 楼•••••知名人士三级培养:主要有小型的 、 、 左右的室内水泥池,采光良好,白色透明玻璃钢瓦或塑料薄膜于车间顶部用于培育藻种。
接下来我主要简单的讲一下容器和工具的洗涤、消毒。
培藻过程中所有的容器和工具,比如锥形瓶、矿泉水桶、搅拌棒等必须经过去污渍、肥皂等刷洗,之后再用消毒后的蒸馏水冲洗 遍。

实验一 微藻的培养基配制
一、实验目: 掌握微藻的培养基配制方法。 以海水单胞藻培养液通用配方“f/2”为例
二、实验原理 藻类的培养液必须具备藻类的生长繁殖所需要的各种营养元
素,并且营养盐的比例应该符合藻类生长繁殖的需要。不同种 类的微藻对营养盐的质和量的需求不同,各有其特殊性,因此, 制定某种微藻的一个培养液配方时,首先必须进行一系列的试 验,了解这该种藻类对营养的要求,并在使用中验证配方的效 果,加以ቤተ መጻሕፍቲ ባይዱ进,使配方达到更理想的水平。藻类对营养盐的需 求也有很多共同点,因而一些培养液配方(如F/2)可应用于多 种藻类的培养。
小球藻
扁藻
球等鞭金藻
1、血球计数板计数方法:
(1) 搅拌:由于藻类细胞在培养液中分布不均匀,所以在取产前必须进行 搅拌,搅拌后立即取样。 (2)固定、稀释:运动细胞需加碘液杀死才能计数。如细胞浓度过大,计数 困难,需把水样稀释到适宜的程度。(附:鲁哥氏液(Lugol‘s Solution)又称
进行微藻培养时,可根据培养藻类对营养的要求,选用合适 的配方,在消毒水中按配方加入各种营养物质配成。所加肥料 应保持清洁,某些不清洁肥料必须消毒,预防敌害生物通过肥 料污染。
绿藻培养液配方:
①海洋三号扁藻培养液(海洋研究所,1960):
NaNO3
0.1g
2Na3C6H5O7﹒ 11H2O 0.02g
培养液是根据培养液配方配制的。为了减少每次称量的麻 烦,固体的营养元素一般都配成母液(如浓缩1000倍的母 液),在使用时,只要吸取一定的量加入培养液中即成。主 要营养元素可以单项营养元素配成母液,也可以分成若干组, 每组2种或多种营养元素同配在一起。微量元素和辅助生长有 机物质也多种组合在一起,配成母液。在浓营养溶液中一般 生物因不能忍受而死亡。
