Can propylene glycol kill bacteria?
Propylene glycol has antimicrobial properties and can inhibit the growth of some bacteria. However, in order to effectively kill bacteria, propylene glycol would need to be used in high concentrations, which may not be safe for certain applications. It is commonly used as a preservative in products to prevent bacterial growth rather than as a direct antibacterial agent.

What inhibits bacterial growth but does not kill bacteria?
Bacteriostatic agents inhibit bacterial growth by preventing their reproduction and division, but do not directly kill the bacteria. Examples include certain antibiotics, refrigeration, and desiccation.
What is the function of each ingredient of nutrient agar?
Agar: Acts as a solidifying agent to provide a solid surface for bacterial growth. Beef extract: Provides amino acids, vitamins, and minerals as nutrients for bacterial growth. Peptone: Another source of amino acids and peptides for bacterial metabolism. Sodium chloride: Provides essential ions for bacterial cell function and maintaining osmotic balance.
What is broth dilution?
Broth dilution is a method used in microbiology to determine the minimum inhibitory concentration (MIC) of an antimicrobial agent. It involves serially diluting the antimicrobial agent in liquid growth medium (broth) containing the bacteria being tested. The lowest concentration of the antimicrobial agent that inhibits visible bacterial growth is considered the MIC.
Identify 3 ways in which the m291 decon kit decontaminates your skin?

What is the purpose of adding rose Bengal and streptomycin solution in the rose Bengal agar medium?
Rose Bengal agar is used for the selective isolation of fungi, particularly Cryptococcus species. Rose Bengal inhibits bacterial growth while allowing fungal growth. Streptomycin solution is added to the medium as an antimicrobial agent to further inhibit bacterial growth and enhance the selection of fungal colonies.
What bacterial agent is contagious person to person?
