牛肉膏 meaning in English
beef extract
beet yellows virus
Examples
- The results showed that : adding tryptone , soy peptone . beef extract , com extract and cys - hcl to jaj could obviously promote the growth of blm and bbm ; by the orthogonal experiment of three elements and three levels , a satisfying jaj compound medium was acquired which included corn extract ( 0 . 3 % ) , soy peptone ( 0 . 05 % ) and cys - hcl ( 0 . 025 % ) . nextly , after establishing a selective bifidobacterium medium , the effects of jaj on the growth of bifidobacteria in vivo were studied , using healthy mouse of kunming species as experimental animal
研究了以菊芋汁为主要原料的双歧杆菌培养基，大量试验结果表明，在菊芋汁中添加胰蛋白胨、牛肉膏、大豆蛋白胨、玉米浆和半胱氨酸盐酸盐等成分，对双歧杆菌有明显的促进生长作用；利用大豆蛋白胨、玉米浆和半胱氨酸盐酸盐设计了三因素三水平的正交试验，确定了菊芋汁复合培养基的优化配方：菊芋汁+ 0 . 3玉米浆+ 0 . 05大豆蛋白胨+ 0 . 025半胱氨酸盐酸盐。 - Shake - flask culture condition of lysine fermentation were studied with czl . appropriate feeding of organic niteogen sources was favorable for fermentation jn our experiment , the concentations of the yeast extract and beef extract were 15g / l and 25g / l . the initial ( nh02so4 and glucose concentrations suitable for fermentor production ranged form 55g / l and 150 - 180g / l respectively
通过摇瓶发酵实验初步确定czl的发酵条件为：初糖： 150 - 180g / l ，采用无机氮源和有机氮源配和使用，最佳组合是：硫酸铵质量浓度为55g / l ；酵母膏质量浓度为15g / l ，牛肉膏质量浓度为25g / l为最佳。 - Isolate all grew well in the culture medium with initial ph 4 - 10 , the optimal growth temperature range was from 28 to 30 . 5 degree c . it grew well on the medium for fungi growth , such as pda medium and czpek medium etc , and also grew well on the cause ' s i medium and the non - nitrogen medium , but little growth on the luria bertani medium ( lb ) and beef extract peptone medium . it did not need special nutrition factors for growth , but source of the carbon was the key factor to growth , all of its nutrition needs were different from that of common bacteria
该菌在初始ph4 - 10的培养基中都能够生长，生长最适温度范围为28 - 30 . 5 ，在pda 、查氏等真菌培养基中生长旺盛，在高氏1号和无氮源培养基中同样生长良好，而在lb与牛肉膏蛋白胨等细菌培养基中生长很差，碳源是其生长的关键因子，这有别于一般细菌的营养需求。 - Seed culture conditions of bacillus licheniformis ts - 01 were firstly investigated . the results showed that the optimal growth temperature was 40 c ; the suitable seed culture medium was beef extract soya peptone medium ; the optimal initial ph was 7 . 5 ; the optimal seed culture time was 13h ~ 14h
首先对地衣芽孢杆菌ts - 01的种子培养条件进行了研究，得到的结果为：最适生长温度为40 ；较适合的种子培养基为牛肉膏大豆蛋白胨培养基；最适初始ph值为7 . 5 ；种龄为13h 14h 。
