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 首先對地衣芽孢桿菌ts - 01的種子培養條件進行了研究,得到的結果為:最適生長溫度為40 ;較適合的種子培養基為牛肉膏大豆蛋白胨培養基;最適初始ph值為7 . 5 ;種齡為13h 14h 。

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 該菌在初始ph4 - 10的培養基中都能夠生長,生長最適溫度范圍為28 - 30 . 5 ,在pda 、查氏等真菌培養基中生長旺盛,在高氏1號和無氮源培養基中同樣生長良好,而在lb與牛肉膏蛋白胨等細菌培養基中生長很差,碳源是其生長的關鍵因子,這有別于一般細菌的營養需求。

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 通過搖瓶發酵實驗初步確定czl的發酵條件為:初糖: 150 - 180g / l ,采用無機氮源和有機氮源配和使用,最佳組合是:硫酸銨質量濃度為55g / l ;酵母膏質量濃度為15g / l ,牛肉膏質量濃度為25g / l為最佳。

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 研究了以菊芋汁為主要原料的雙歧桿菌培養基,大量試驗結果表明,在菊芋汁中添加胰蛋白胨、牛肉膏、大豆蛋白胨、玉米漿和半胱氨酸鹽酸鹽等成分,對雙歧桿菌有明顯的促進生長作用;利用大豆蛋白胨、玉米漿和半胱氨酸鹽酸鹽設計了三因素三水平的正交試驗,確定了菊芋汁復合培養基的優化配方:菊芋汁+ 0 . 3玉米漿+ 0 . 05大豆蛋白胨+ 0 . 025半胱氨酸鹽酸鹽。

So terrie berenden , a pet shop owner in the southern dutch town of zelhem , created a beer for her weimaraners made from beef extract and malt 所以,茲爾漢姆郡荷蘭鎮南部的一家寵物店的店主特莉?布蘭登,用麥芽和牛肉汁專為她的威瑪獵犬釀制了一種寵物“啤酒” 。

The beef extract , a beef derivative , is a source of organic carbon , nitrogen , vitamins , and inorganic salts 牛肉萃取物是一種牛肉衍生制品,可以作為有機碳、氮、維生素與無機鹽類的一個來源。

It ' s made from beef extract and malt , and contains other ingredients designed to tickle the doggy palate 這種啤酒主要是由牛肉萃取物和麥芽做成的,然后還放了些能調動狗味覺的添加劑。
