eDNA
Environmental monitoring technique
DNA is the genetic material of the living organisms that contain characteristics related information of the specific organism. In modern laboratory diagnostics, DNA analysis is a very useful and sensitive tool.
For the diagnosis of target DNA, there is an essential DNA sequence required for the laboratory work. This can be achieved by nucleic acid hybridization, DNA probes, and DNA chips microarray of gene probes all of these tools are essential for DNA diagnosis purposes.
DNA analysis for environmental monitoring
Today, environmental pollution is a major problem that we face. Pollutants that cause environmental pollution degrade the purity of our environment. Some several pathogenic microorganisms and viruses may cause environmental pollution, particularly water pollution.
DNA analysis can also be employed for the specific detection of indicator bacteria such as Escherichia coli to check the quality of potable water. By using DNA probes we can detect the specific gene of Escherichia coli that is present in the sample. The DNA analysis technique is very sensitive and is capable of identifying a single Escherichia coli cell in 100 ml of water.
It also helps to detect pathogenic organisms such as Salmonella, Vibrio, and…
