英汉例句
- An auxotroph requires, in addition to the principal carbon source, one or more organic nutrients.
缺陷營養生物除需要主要碳源外，還需要一種或幾種有機養料。 - The reverse frequency of donor and receptor for auxotroph and resistance is less than 10~(-9), protoplast transformation is carried out in SMM containing 30% oolyethene glycol (MW 6000) and 20mg/ml DNA at controtledtime and temperature.
轉化子有的是原養型,有的在含利福平(10單位/亳陞)和鏈黴素(200單位/亳陞)的培養基上能生長,也有的兼而有之。 - Original strain, Corynebacterium glutamicum AS1542, was mutanted by DES and UV. protoplast irradiation. Finally, a higher L-tryptophan producing strain,T11-6 was obtained. It was a double auxotroph of phenylalanine and tyrosine.
