Detecting the Effects of Fungicides on Soil Bacteria Populations using Denaturing Gradient Gel Electrophoresis (DGGE)
Rationale Fungicide applications are a necessary practice to discourage disease development in most high quality turfgrass areas. Little is known, however, about the effects that fungicides have on resident microbial community of the soils supporting turfgrass sites. Soil bacteria are responsible for important processes including pesticide degradation, nutrient cycling, and organic matter break...
متن کاملConformation sensitive gel electrophoresis for simple and accurate detection of mutations: comparison with denaturing gradient gel electrophoresis and nucleotide sequencing.
Previously, an assay called conformation sensitive gel electrophoresis (CSGE) was developed for scanning PCR products for the presence of single-base and larger base mismatches in DNA. The assay was based on the assumption that mildly denaturing solvents in an appropriate buffer can accentuate the conformational changes produced by single-base mismatches in double-stranded DNA and thereby incre...
متن کاملDenaturing gradient gel electrophoresis (DGGE) as a tool for identification of marine nematodes
Many phyla of marine invertebrates are difficult to identify using conventional morphological taxonomy. Larvae of a wider set of phyla are also difficult to identify as a result of conservation of morphology between species or because morphological characters are destroyed during sampling and preservation. DNA sequence analysis has the potential for identification of marine organisms to the spe...
متن کاملApplication of denaturing gradient gel electrophoresis (DGGE) for assessing fecal pollution sources at a recreational beach.
We investigated the effectiveness of Escherichia coli community fingerprinting for identifying fecal pollution sources impacting a recreational beach. E. coli in water collected from the beach, nearby creek and storm sewer outfall were enumerated using membrane filtration, while E. coli communities were characterized following polymerase chain reaction analysis and denaturing gradient gel elect...
متن کاملDenaturing Gradient Gel Electrophoresis (DGGE) in Microbial Ecology – Insights from Freshwaters
Although freshwater ecosystems support a great diversity of life, knowledge of its total diversity is far to be complete, particularly among microbes (Dudgeon et al., 2006). Aquatic microorganisms are pivotal in several biogeochemical processes, playing a key role in the recycling of organic material, or contributing to energy transfer in food webs, since they constitute food sources to micro-f...
