Detergent effects on cell walls
Webthese detergents with urea are the most effective for this purpose. During the ex-traction of proteins from bacterial cells under the conditions studied, the release of RNA into solution also occurs, while DNA mostly remains inside the cells. The proposed treatment does not break the bacterial cell walls; proteins probably are WebJul 1, 2013 · 2. Non-mechanical methods. Non-mechanical methods involve the addition of enzymes or chemicals that specifically break down cell wall components. They are often used in combination with mechanical force to ensure complete disruption of the cell. The disadvantage to their use is that they often have to be removed from the sample afterwards.
