Lab Report Title Page: Determine Disinfectant and Antiseptic Effectiveness Using Zone Inhibition Method Prepared for: By: Date: Introduction Page: Abstract This study is to examine the effects of different types of disinfectants by disk diffusion method using common agents such as Betadine‚ Clorox‚ Crest‚ Kiss My Face‚ Listerine‚ and Lysol. Wound care and general cleaning of home surfaces is a part of daily activity for many of the general population. Knowing

higher the concentration of antiseptic‚ the more powerful it will be at inhibiting/ killing microorganisms which cause bacterial growth.” This theory supports my result because as you can see the zone of inhibition increases due to the increasing concentration of antiseptic. The higher concentration of antiseptic means it has been less diluted‚ which means its more stronger than other more diluted concentrations‚ this high concentration will determine how powerful the antiseptic will be at killing/inhibiting

beneficial bacteria. Finally‚ you would definitely want to know that the compound is effective against the organism(s) you are trying to eliminate. This project shows you one method of measuring the effectiveness of an antimicrobial agent against bacteria grown in culture. This is called the Kirby-Bauer disk-diffusion method‚ and here is how it works. The bacteria of interest are swabbed uniformly across a culture plate. Then a filter-paper disk‚ impregnated with the compound to be tested‚ is placed

Olivia Teasdale Mrs. Gaspar SBI3U1 10/07/13 The Effect of Disinfectants and Antiseptics on Bacteria Growth Abstract The purpose of this lab was to determine the effect of disinfectants and antiseptics on bacterial growth. By observing the effects of 5 different inhibitors including alcohol‚ bleach‚ soap solution and distilled water‚ it was determined what antiseptic or disinfectant was able to best inhibit this kind of bacterial growth. Nutrient Agar was poured into a Petri dish with four quadrants

Effects of Antiseptics and Disinfectants Purpose: The purpose of this lab is to discover substances that can slow the growth of‚ or kill‚ microorganisms. Hypothesis: The antiseptic that will prevent the growth of bacteria the most is iodine. The disinfectant that will prevent the growth of bacteria the most is bleach. Procedure: To begin the lab‚ turn the agar plate over and divide the plate into four quadrants and label the agar plate whether you

were not expected. Morning fresh which costs the most was expected to have the largest zone of inhibition but this was not the case. Palmolive has the largest zone of inhibition having an 0.8 cm larger diameter then morning fresh had. It was expected that ultra would have the smallest zone of inhibition as it was the cheapest. The sponges results were also interesting as there was no clearly seen zone of inhibitions that were noticeable enough to be able to measure. Discussion The results that were

Antiseptics and Disinfectants Introduction Antiseptics and disinfectants are extensively used in hospitals and other health care settings for a variety of topical and hard-surface applications. A wide variety of active chemical agents (biocides) are found in these products‚ many of which have been used for hundreds of years‚ including alcohols‚ phenols‚ iodine‚ and chlorine. Most of these active agents demonstrate broad-spectrum antimicrobial activity; however‚ little is known about the mode of

Method 1. Sterilise all of your equipment with ethanol‚ blue flame or disinfectant if you can flame it. 2. Collect all equipment together ensuring you collect your goggles and gloves as you are using a flame and gloves and goggles are part of safety precautions. (don’t wear gloves with messing with Bunsen burner only goggles‚ but use gloves when messing with chemicals ensuring goggles on all the time) 3. Clean your surface with disinfectant to sterilise your lab work surface‚ this will prevent

The Relation of Antiseptics and Bacteria Growth Purpose: To explore the effectiveness of different levels of concentration of antiseptic and antibacterial products’ prevention of bacterial growth. Question: Amongst common household products‚ which antiseptic and level of concentration is more effective at inhibiting the growth of bacteria? Introduction: Antiseptics are antimicrobial substances used on living tissue to reduce the possibility of infection‚ putrefaction or sepsis. The word “anti”
