Bacterial Community DNA Extracted from Soils Polluted with Heavy Metals
This paper describes the application of two direct and one indirect methods for the extraction of microbial community DNA from soils polluted with heavy metals. DNA was extracted directly from soil using a gentle method based on soil incubation at 37°C with proteinase K and SDS, or the method was modified by the addition of a bead beating step. The indirect approach was based on the RNA/DNA ext...
متن کاملBiotic contexts alter metal sequestration and AMF effects on plant growth in soils polluted with heavy metals.
Investigating how arbuscular mycorrhizal fungi (AMF)-plant interactions vary with edaphic conditions provides an opportunity to test the context-dependency of interspecific interactions. The relationship between AMF and their host plants in the context of other soil microbes was studied along a gradient of heavy metal contamination originating at the site of zinc smelters that operated for a ce...
متن کاملPhytoremediation of soils polluted by heavy metals using Vetiver grass and Tall Fescue
Phytoremediation is a biological method to improve soils contaminated with heavy metals. The objective of the present research was to study the capability of Vetiver grass and Tall Fescue in refining and reducing pollution of Cd, Cu and Zn from contaminated soils. The research was implemented in greenhouse during two separate tests (Vetiver grass and Tall Fescue) in a completely randomized desi...
متن کاملPhytoremediation of heavy metals polluted environments
The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...
متن کاملPhytoextraction of heavy metal polluted soils using Sedum plumbizincicola inoculated with metal mobilizing Phyllobacterium myrsinacearum RC6b.
The aim of this study was to investigate the effects of metal mobilizing plant-growth beneficial bacterium Phyllobacterium myrsinacearum RC6b on plant growth and Cd, Zn and Pb uptake by Sedum plumbizincicola under laboratory conditions. Among a collection of metal-resistant bacteria, P. myrsinacearum RC6b was specifically chosen as a most favorable metal mobilizer based on its capability of mob...
