Which of these disinfectants does denaturing proteins?
Iodine, in both tincture and iodophor forms, is an effective antiseptic. Alcohols, including ethyl alcohol and isopropyl alcohol, are commonly used antiseptics that act by denaturing proteins and disrupting membranes.

Thymol was found to be the most effective with the lowest MIC values of 1.0 and 1.2 mmol 1-1 against Salm. Typhimurium and E. coli, respectively. After thymol, the antimicrobial order of the natural organic compounds was carvacrol > eugenol > cinnamic acid > diacetyl.
Which one of the following is most resistant to chemical biocides?
Different groups of bacteria vary in their susceptibility to biocides, with bacterial spores being the most resistant, followed by mycobacteria, then Gramnegative organisms, with cocci generally being the most sensitive.
Is formaldehyde considered a disinfectant?
Formaldehyde is used as a disinfectant and sterilant in both its liquid and gaseous states. … Ingestion of formaldehyde can be fatal, and long-term exposure to low levels in the air or on the skin can cause asthma-like respiratory problems and skin irritation, such as dermatitis and itching.
