True or False: Cationic and acid-anionic detergents have a killing effect for some microbes.

Cationic and acid-anionic detergents can indeed exhibit antimicrobial properties, particularly against certain types of microbes. Cationic detergents, such as quaternary ammonium compounds, are well-known for their ability to disrupt microbial cell membranes, leading to cell lysis and death. They are effective against various bacteria, fungi, and certain enveloped viruses. Acid-anionic detergents, often used in personal care and cleaning products, can also have a limited antimicrobial effect due to their ability to lower the pH and disrupt microbial metabolism.

This killing effect can vary based on concentration and the type of microbes present. However, it is important to note that while these detergents can provide some level of microbial control, they are not as universally effective as some other disinfectants, especially against spores or non-enveloped viruses.

The statement is true because both types of detergents can have a killing effect on some microbes, supporting the premise that they possess certain antimicrobial properties.
