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”

Kaitlyn Swearingen Effects of the Pigmentation of an Onion Cell within 40% Ethanol and Deionized Water Purpose: To measure the amount of pigment in a solution of 40% ethanol and deionized water both containing pieces of an onion with a spectrometer. Hypothesis: 40% ethanol breaks down the cell creating less surface area and spreading out the pigment while the deionized water absorbs the pigment in a greater surface area. Procedure: Add 10ml of deionized water and 40% ethanol to a 6-dram vial Add

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

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

Antiseptics Definition An antiseptic is a substance which inhibits the growth and development of microorganisms. For practical purposes‚ antiseptics are routinely thought of as topical agents‚ for application to skin‚ mucous membranes‚ and inanimate objects‚ although a formal definition includes agents which are used internally‚ such as the urinary tract antiseptics. Purpose Antiseptics are a diverse class of drugs which are applied to skin surfaces or mucous membranes for their anti-infective

Control by Antibiotics and Antiseptics Lab Report Georgia State University Introduction The fact that each bacterial species‚ and even some of their respective strains‚ responds uniquely to a given antimicrobial makes it necessary to have methods‚ which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By

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
