Control cultures are necessary in evaluating disinfectants to account for the microbial colonies that would have present if the disinfectants were not. If a disinfectant contaminates any of your microbial cultures your results will be skewed.

Disinfectants can be classified in two different ways. One is by what type of chemical they are. For example, the active ingredient in Lysol is O-phenylphenol. Phenol and some other disinfecting chemicals are chemically similar. Another way to classify disinfectants is by how many hard-to-kill microbes they are effective against. High level disinfectants can kill most endospore-forming bacteria which tend to be very resistant. There are intermediate level and low level disinfectants as well.
hi, embalming chemicals have a variety of preservatives, disinfectants and additives which are used to delay decomposition. an embalming chemical is a combination of formaldehyde, glutaraldehyde, ehtanol, wetting and solving agents.
A chemical agent that leaves an instrument clean but not sterile is called a disinfectant. Disinfectants are used to reduce the number of microorganisms on surfaces but may not eliminate all types of bacteria, viruses, or fungi. Therefore, while disinfectants can remove dirt and organic material, they may not achieve complete sterility.
The are a number of disinfectants that are known to be water based. These include disinfectants such as Lysol, Oxy Clean in liquid format, and even Phenolics.
Disinfectable
You should not use disinfectants on food - not if you intend to eat it.
Disinfectants are effective against vegetative cells and viruses, but not endospores.
Disinfectants kill or inhibit the growth of pathogenic microorganisms. Most disinfectants are too harsh to be applied to living tissue, and are applied only to inanimate surfaces. Ammonia, ethanol, and bleach are examples of widely used disinfectants.
