Six experimental stages were designed in our procedure, those are:(1) metabolite recovery and tested sample preparation: the metabolites were recovered by Amberlite XAD-2 absorption, followed by MeOH elution and solvent concentration;(2) antioxidant detection and strain selection: samples were quantitatively analyzed by the inhibition effects on formation of lipid peroxides and TBARS to screen the strains able to produce antioxidants. According to the established screening methods, we chose out a strain of actinomycetes, designed as AMBL-029C;(3) antioxidant purification: the fermentation broth was recovered by a series of separation techniques including centrifugation, Amberlite XAD-2 absorption, followed by MeOH elution and a successive TLC purification. The resulting primary purified compound [temperately designed as AMBL-029C-TS] was further analyzed by HPLC to monitor its purity;(4) physical-chemical characteristics: judging from the acid-base fractionation experiments, and the pH and temperature stability tests, the compound was deduced to be a acidic compound with the properties of low polarity and highly pH and temperature stable;(5) mechanism of the antioxidant: in comparison with some other known antioxidants, TS was subjected to investigate its antioxidant mechanism, together with BHT,-tocopherol, as well as two streptomyces metabolites, homogentisic acid and -phenylpyruvic acid, which were previously isolated as the natural antioxidants in our laboratory.
针对本实验目的，我们设计了以下的实验步骤﹔（1）二次代谢物回收及检测样本处理：我们将发酵所得的培养上清液，利用疏水吸附性树酯Amberlite XAD-2吸附回收，并以甲醇溶离及真空减压浓缩脱水等方式处理，以取得提供抗氧化活性筛选之检测样本；（2）抗氧化活性检测及菌种筛选：以「过氧化脂质」和「硫丙二醯尿」的生成量进行定性定量分析以作为抗氧化物质生产菌筛选之用；经此筛选程序，我们选获了具有抗氧化物质高生产力的菌株，命名为AMBL-029C；（3）抗氧化物质的分离纯化：针对生产菌株的发酵回收处理液，以矽胶薄层色层分离法经物质层析纯化后，并以高效能液相层析法(High performance liquid chromatography；HPLC)分析物质可得一初级纯化物质，命名为AMBL-029C-TS；（4）抗氧化物质的物理化学性质分析：由酸碱转溶（acid-base fractionation）实验得知，此抗氧化物质属於中低极性的强酸性物质，对温度（37℃-100℃）及酸碱度（pH3.0-13.0）均表现出高稳定性；（5）在抗氧化机制探讨方面，我们针对数种不同的抗氧化机制进行探讨，即： 1。

According to one conserved sequences of phage GIL01 from Bacillus thuringiensis,a pair of primers was designed.With overnight cultivations of 35 B.t standard strains and one fermentative strain MZ1 as templates,PCR results showed that 16 strains,which may be lysogenic strains,produced the product with the size about 750 bp as anticipated.

Among them strain MZ1 had been confirmed a lysogenic strain by indicator strain ZK1 after producing phage plaques induced by Mitomycin C.Two templates of overnight cultivation and its DNA from strain MZ1 were then amplified in the same time with five pairs of primers designed from the same phage,and the same products were obtained,suggesting that strain MZ1 was also confirmed a lysogenic strain by PCR method.
MZ1菌株的过夜培养液与指示菌ZK1(血清型H25)混匀并在双层琼脂上培养12 h后出现了滴度为2×107 pfu的噬菌斑，从而证明生产菌株MZ1确为溶原菌；又以GIL01同源性较高的其它四个基因设计引物，分别以MZ1的培养物及其溶原性噬菌体基因组为模板进行PCR扩增，结果两者得到几乎一致的带型，进一步证明了生产菌株MZ1为溶原菌，说明利用PCR法检测鉴定苏云金杆菌的溶原性是可行的。
