Salting out is introduced as the best method for DNA extraction from L. seratta as a food-borne pathogen with the least costand appropriate purity. Although, the best purity was regarding to PCI but PCI is not safe as salting out. In addition, the duration of salting out was less than PCI.
DNA extraction process frees DNA from the cell and then separates it from cellular fluid and proteins so you are left with pure DNA. The three basic steps of DNA extraction are 1) lysis, 2) precipitation, and 3) purification
