| 摘 要： | 目的]鉴定广西北海红树林土壤放线菌的物种多样性.方法]从广西北海红树林土壤中分离、筛选10株典型放线菌菌株,提取基因组DNA,进行16S rDNA PCR扩增与测序,并构建进化树.结果]通过Blast比对,10株放线菌属于2个属,其中8株为链霉菌属(80%),2株为拟诺卡氏菌属(20%).结论]广西北海红树林土壤蕴减着种类丰富的放线菌.
Abstract：
Objective] The aim was to identify the species diversity of Actinomycetes from Mangrove forest in Beihai,Guangxi Province.Method]10 strains of typical Actinomycetes were isolated from Mangrove forest soil,and the Actinomycetes genomic DNA was successful extracted.16S rDNA was amplified by PCR and sequenced by Sanger dideoxy sequencing method.Rcsult]All the sequences were blasted in genbank,eight strains belonged to the genus of Streptomyces (80%),and two strains belonged to the genus of Nocardiopsis (20%).Coacluslon]There are many different Actinomycetes species in Mangrove forest soil samples in Beihai,Guangxi Province.
