耐辐射奇球菌对受损湿地土壤的生态修复研究
Ecological Remediation of the Damaged Wetland Soil by Deinococcus radiodurans
摘要
Abstract
In order to investigate ecological restoration effects of microorganisms and plants in heavy metal-damaged wetlands in the vicinity of estuaries and find a technique suitable to restore the area,the extreme bacterium Deinococcus radiodurans and Suaeda salsa were independently and combinationally used to determine their remediation effects on the wetlands.The results showed that all the treatments could improve physical,chemical and biological properties of the wetlands in the tested area to some extent.Following the treatment of D.radiodurans,the microbial content was significantly increased with concentration of Cd (Ⅱ) reduced by 25.24％,the available phosphorus increased by 12.75％,the organic matter increased up to 13.1％ and water soluble salts reduced by 3.37％.The treatment by D.radiodurans demonstrated better effects on the properties of soil including the available phosphorus,organic matter,microbial content,Cd (Ⅱ) concentration and water soluble salts compared with the other treatments.These results provided a theoretical basis and practical resources for the technology to restore coastal wetland using the extreme microbes.关键词
