摘要:
目的对36株海洋盐单胞菌进行16S rDNA的序列测定和生物学活性的初步分析。方法用PCR方法扩增36株细菌的16S rDNA序列,将获得的全部序列运用Clustal X1.8软件进行多序列比对并用MEGA4.1软件绘制进化树。利用MTT法测定菌株发酵液的细胞毒活性;采用DPPH和ABTS抗氧化模型检测菌株发酵液的抗氧化活性;采用人白细胞弹性蛋白酶(human leukocyte elastase, HLE)抑制剂筛选模型检测菌株发酵液对HLE的抑制率。结果经与GenBank数据库比对,36株菌均与盐单胞

Abstract:
ObjectiveTo determine the 16S rDNA sequences of 36 strains of Halomonas sp. isolated from the seawater of the East China Sea and to study their bioactivities. MethodsThe 16S rDNA sequences of all isolated strains were amplified by PCR, and the obtained se
