求翻译：我分离出51株放线菌从不同的四个土壤样品中。依据菌落特征，我分离和筛选出8株典型放线菌菌株从他们之中，我为了扩大和增加它所以对它进行16S rDNA PCR，同时测定它的序列，并对其生理生化特征及系统分类地位进行了研究。结果表明，是什么意思？

I isolated 51 actinomycetes from four different soil samples. Based on colony characteristics, separated and screened eight typical strains of actinomycetes from them, in order to expand and increase it its 16s rDNA pcr simultaneous determination of its sequence, and its physiological and biochemica
