1.When the parent ion was m/z 180 and the exact CID voltage was 0.5v,the result was satisfactory.
结果选择氯胺酮的特征离子m/z180为母离子,CID电压为0.5v进行MS/MS分析;收藏指正
2.The results from the P.Graham and Castleman’s study on CH3I also supported this conclusionIn the mass spectra ,the parent ion peak was clearly recorded .
Graham等人及Castleman等人在790nm左右飞秒激光系统下也分别对碘甲烷分子进行了研究,都认为碘甲烷分子先电离然后解离。收藏指正
3.At present the titre of BLM is lower, such as the titre of parent strain U-43 is only 25μg/mL. In order to obtain higher BLM-producing strain, 5 different breeding methods were used to treat the parent strain U-43 separately. At last, high-production strain, L-20 was screened by the method of N~+ Ion implantation.
目前博莱霉素的效价很低,而本实验的出发菌株U-43效价只有25μg/mL,为了提高效价,实验通过五种方法分别对博莱霉素出发菌株U-43进行诱变,最后通过N~+离子注入选育出高产菌株L-20,并对原始发酵培养基进行优化及前体加入浓度和加入时间进行了选择,使博莱霉素的效价显著提高。收藏指正
