一种鞘氨醇杆菌(Sphingobacteriumsp.)DDT-6携带的质粒
摘要：
本发明公开了一种DDT残留污染土壤的生物修复方法，包括：将鞘氨醇杆菌(Sphingobacterium sp.)DDT-6或其携带的质粒或包含该质粒的转化子接种到残留DDT的土壤中，鞘氨醇杆菌DDT-6的保藏号为CCTCC M 208116。本发明鞘氨醇杆菌DDT-6携带的质粒具有降解DDT的基因，使得它具有降解DDT的性能，更重要的是该质粒为可转移质粒，通过在土壤中接种该质粒或者含该质粒的菌株，该质粒可以转化到土壤微生物中，甚至可能与土壤微生物中基因发生重组，一方面解决了外源微生物在土壤中生存困难的问题，另一方面降解菌能最大限度的分散，尽可能地降解DDT。
摘要（英）：

The invention discloses a bioremediation method for soil contaminated by residual DDT, comprising the following steps: inoculating Sphingobacterium sp. DDT-6 or plasmid carried thereby or transformant containing the plasmid to soil with residual DDT, wherein the collection number of the Sphingobacterium sp. DDT-6 is CCTCC M 208116. The plasmid carried by the Sphingobacterium sp. DDT-6 has genes for degrading DDT, thus having the performance of degrading DDT-6, more importantly, the plasmid is transferable, and can be transformed into soil microorganisms and even possibly is subject to gene recombination with genes in soil microorganisms through inoculating the plasmid or strains containing the plasmid to the soil, thereby solving the problem that exogenous microorganisms are difficult to live in soil on one hand, and ensuring that degrading bacteria can be maximally dispersed to degrade the DDT as much as possible on the other hand.
