通过PCR扩增并测序获得了三斑海马(Hippocampus trimaculatus)线粒体DNA(mtDNA)全序列。三斑海马线粒体基因组全序列长度为16 534 bp(GenBank登录号为KJ956892),编码37个基因,包括13个蛋白编码基因、22个tRNA基因和2个rRNA基因。非编码区域包括1个控制区(D-loop)及一个轻链复制起始区域。大部分基因由H-链编码,包括14个tRNA基因、2个rRNA基因、12个蛋白编码基因;只有ND6和8个tRNA基因是在L-链编码。预测的22个tRNA基因的二级结构均为典型的三叶草状。基因间隔一般1 ~ 14 bp不等。此外,还存在7处碱基重叠,其中,4处是鱼类和脊椎动物典型的基因重叠位点。总的碱基含量分别为,A 32.7%,C 23.4%,G 14....

The article intends to make a study of the biodegradability and its correlation with its quantitative structure of the alkyl xanthates flotation collectors in hoping to learn to control and prevent the pollution of the agents as well as to provide a theory for the synthesis and application of the flotation agents.It is for the said purpose,we have chosen five kinds of alkyl xanthates flotation collectors as research goal with the method of shaking the cultivated solution of the aerobic biodegradability of ethyl xanthate,the isopropyl xanthate,n...
