Guanosine overproducing mutant was derived from Bacillus subtilis T1001 by using ultraviolet and diethyl sulfate. The mutant was selected directionally and step wisely on the agar plates containing methionine sulfoxide and 8 azaguanine(8 AG).

以枯草芽孢杆菌T1 0 0 1为出发菌株，经紫外线、硫酸二乙酯逐级诱变处理，选育出腺嘌呤缺陷型菌株，然后经蛋氨酸亚砜、8 氮鸟嘌呤( 8 AG)结构类似物平板定向筛选，获得鸟苷高产菌株TA2 0 8。

objective To test association of changes of serum folic acid level with MTRR A66G genetype in the mild-to-moderate hypertensive patients..

目的 探讨轻中度高血压患者蛋氨酸合成还原酶 G66A多态性位点与血清叶酸水平变化间的关系。

The optimum condition for separating and purifying SAM was using the solution at pH of 5.0 containing 3.0 g SAM per liter at the flow velocity of 6 L/h through the ion-exchange column (φ50 mm×1500 mm)filled with D152 resin. Impurities were removed first by eluting the column with double-distilled water and acetic acid, and then with 9 L to 15 L of sulfuric acid of 50 mmol/L concentration at the flow velocity of 6 L/h.
