取1μg左右的质粒DNA加入到200ml EHA105感受态细胞中，混匀后，冰浴30min，-70℃放置10min 。再在37℃水浴5min或42℃水浴1min，接着冰浴2min，加入800mlYM液体培养基28℃，175rpm摇培3hr后涂在含50μg/ml Kanamycin的YM平板上。28℃培养到形成单菌落。其中 YM 可以用LB 代替 ，*次的 CaCl2 溶液可用溶液（0.1MCaCl2 0.01Tris-HCl（7.0） 0.01 DTT）替代。
(一)实验目的
了解细菌生长曲线的持点及测定原理，学会用比浊法测定细菌的生长曲线。
(二)实验原理
将一定数量的细菌，接种于适宜的液体培养基中，在适温下培养，定时取样测数，以菌数的对数为纵坐标，生长时间为横坐标，作出的曲线称为生长曲线。该曲线表明细菌在一定的环境条件下群体生长与繁殖的规律。一般分为延缓期、对数期、稳定期及衰亡期四个时期，各时期的长短同菌种本身特征、培养基成分和培养条件不同而异。
比浊法是根据细菌悬液细胞数与混浊度成正比，与透光度成反比关系，利用光电比色计测定细胞悬液的光密度(即OD值)，用于表示该菌在本实验条件下的相对生长量。
实验设正常生长、加酸YZ和加富培养等三种处理，以了解细菌在不同生长条件下的生长情况。

Take about 1μg of plasmid DNA was added to 200ml EHA105 competent cells, mix, ice bath 30min, -70 ℃ placed 10min. The cells were further incubated in a water bath at 37 ° C for 5 min or a 42 ° C water bath for 1 min followed by an ice bath for 2 min. The resulting mixture was added to 800 ml of YM liquid medium at 28 ° C for 3 hr at 175 rpm and then plated on YM plates containing 50 μg / ml of Kanamycin. 28 ° C to form a single colony. Where YM can be replaced by LB, the first CaCl2 solution can be used solution (0.1MCaCl2 0.01Tris-HCl (7.0) 0.01 DTT) replaced.
(A) the purpose of the experiment
Understand the point of bacterial growth curve and determination of principle, learn to use turbidimetric method to measure the growth curve of bacteria.
(B) experimental principle
A certain amount of bacteria, inoculated in a suitable liquid medium, cultured at a suitable temperature, regular sampling measurements, the logarithm of the number of bacteria for the vertical axis, the growth time for the abscissa, the curve is called the growth curve. The curve shows that the bacteria in certain environmental conditions, population growth and reproduction of the law. Generally divided into delaying period, log phase, stable period and decay period of four periods, the length of each period with the characteristics of the bacteria themselves, the medium composition and culture conditions vary.
Turbidimetric method is based on bacterial suspension cell number and turbidity is proportional to the transmittance is inversely proportional to the use of photoelectric colorimeter cell suspension optical density (ie OD value), used to indicate that the bacteria in this experiment The relative amount of growth under conditions.
The experiment set up normal growth, acid inhibition and enrichment culture three treatments to understand the growth of bacteria in different growth conditions.
