为了保护和开发微生物资源,从连云港台北盐场采集卤水,通过分离筛选获得5株嗜盐古菌,编号分别为23、25、40、174和178,均为革兰氏阴性,杆状。用嗜盐古菌16 S rRNA基因通用引物进行16 s rRNA基因扩增,克隆后测序,对测序结果进行系统发育学分析研究并构建系统发育树。结果表明:嗜盐古菌菌株23、40、174和178属于盐红杆菌属(Halorubrum),25属于盐盒菌属(Haloarcula)。
為瞭保護和開髮微生物資源,從連雲港檯北鹽場採集滷水,通過分離篩選穫得5株嗜鹽古菌,編號分彆為23、25、40、174和178,均為革蘭氏陰性,桿狀。用嗜鹽古菌16 S rRNA基因通用引物進行16 s rRNA基因擴增,剋隆後測序,對測序結果進行繫統髮育學分析研究併構建繫統髮育樹。結果錶明:嗜鹽古菌菌株23、40、174和178屬于鹽紅桿菌屬(Halorubrum),25屬于鹽盒菌屬(Haloarcula)。

For the protection and development of microbial resources ,five halophilic archaea strains numbered 23 ,25 ,40 ,174 and 178 which are Gram-negative and rod-shaped were isolated from Taibei saltern of Lianyun-gang .16S rRNA genes were obtained by PCR with archaea universal primers of 16S rRNA gene .After cloning and sequencing ,compared the nucleotide sequences with closely species were phylogenetic analyzed and phylag-enetic trees were constructed .The results showed that halophilic archaea strains 23 ,40 ,174 and 178 belonged to genus H alorubrum ,and strain 25 belonged to genus H aloarcula .
