沉积物样品收集的海岸圣地亚哥放线菌多样性进行了分析，使用文化独立的技术。八个新的操作分类单位（OTU）在链霉菌科以及新的多样性在以前培养的海洋OTU。还检测到了属于海洋放线菌属Salinispora的序列，尽管该属仅在热带环境中报道过。从加那利盆地（3814米）和南太平洋环流（5126和5699米）的海洋沉积物的独立分析也显示Salinispora序列提供了进一步的支持，该属在深海沉积物中的发生。培养盐孢菌的努力。从这些样本中分离出来还没有成功。这是首次报道盐孢属（Salinispora spp.）从海洋沉积物> 1100米，这表明该属的分布比以前认为的更广泛。
Sediment samples collected off the coast of San Diego were analyzed for actinomycete diversity using culture independent techniques. Eight new operational taxonomic units (OTUs) in the Streptomycetaceae were identified as well as new diversity within previously cultured marine OTUs. Sequences belonging to the marine actinomycete genus Salinispora were also detected, despite the fact that this genus has only been reported from more tropical environments. Independent analyses of marine sediments from the Canary Basin (3814 m) and the South Pacific Gyre (5126 and 5699 m) also revealed Salinispora sequences providing further support for the occurrence of this genus in deep-sea sediments. Efforts to culture Salinispora spp. from these samples have yet to be successful. This is the first report of Salinispora spp. from marine sediments >1100m and suggests that the distribution of this genus is broader than previously believed.
