Inhibition

the zone of inhibition for each antibiotic. To collect our data, we measured the diameter of the zone of inhibition around the antibiotic, in centimeters and converted it to millimeters. We recorded these measurements and combined our data with a group who had similar data to ours, to obtain six replicates total. Our control samples where different then the antibiotics because there was not a zone of inhibition around them and five of the six antibiotics did had a zone of inhibition. Finally, we

Concentration Measurement of zone of inhibition (mm) Mean length of inhibition zone(length excluding disk) Mean area in (mm2 ) Description of bacteria growth Mouthwash 1x 6.375 91.9 -medium ring of inhibition, almost fully undisturbed by bacteria 1/10x 2.5 28.46 -small ring of inhibition, some bacteria growing over 1/20x 1.75 18.89 -very slight ring of inhibition 0x 0 0 -entire section covered in bacteria Mr. Clean 1x 12.5 240.41 -relatively large ring of inhibition around disk, undisturbed by bacteria

item with the largest zone of inhibition. Starting with the largest zone of inhibition and ending with the smallest, Betadine was the largest, then the Lysol cleanser, liquid hand soap, rubbing alcohol, Neosporin, Germ-X, and the smallest was the distilled water. Betadine had the largest zone of inhibition of 39.5mm and rubbing alcohol which does not have the largest zone of inhibition of 17.7mm, which rejects the hypothesis. Betadine had the largest zone of inhibition because the active ingredient

Effectiveness of bacitracin, gentamicin and chloramphenicol on the growth of Escherichia coli Introduction: Escherichia coli (E. coli) is a bacterium commonly found in the digestive system of humans and animals. Although it is mainly harmless and helps promote a healthy digestive system, some strains can be pathogenic and cause illness such as diarrhea, urinary tract infections, respiratory infections and even pneumonia. What makes E. coli pathogenic is the release of a toxin called Shiga. These

Affect the Growth of Bacteria of the Digestive System? Using agar diffusion test, the effect of caffeine on the growth of bacteria is measured by the zones of inhibition established around the caffeine impregnated filter paper discs. Different concentrations of caffeine were tested, from 0.2 mg/mL to 1.0 mg/mL. The sizes of zones of inhibition was

and the gram positive Staphylococcus epidermidis bacteria. Quantitative data was taken using the filter-paper disk method to determine the zones of inhibition produced by the three antimicrobials. The results collected showed that Melaleuca alternifolia (tea tree) oil is an effective broad spectrum antimicrobial, while honey produced partial inhibition with an outer ring of stimulation signifying that the honey is merely bacteriostatic for a short period of time before growth reoccurs. The Capsicum

Introduction: Antibiotics have the ability to kill or hinder the growth of bacteria. Antibiotics contain compounds that are naturally produced by organisms to combat diseases caused by microbes. Discovery of penicillin by Sir Alexander Fleming became the first stepping stone of many new antibiotics of today’s modern medicine. Antibiotics typically invade the very components that make up bacteria, such as cell walls and metabolic pathways (Sato et al., 2014). However, frequent mutations of bacteria

Retroactive Inhibition in Memory THE EFFECT OF MEMORY IN LEARNING AMONG UPSI STUDENT Member’s Name: Muhammad Aiman Bin Bahnan Siti Nur Aqilla Bt Mohamat Helmee  D057683 Afiqatulathirah Normukminah Binti Zun D057630 Alice Goh Yea Mien D061104 Retroactive Inhibition in Memory The hypothesis that can be deduce in the study is when there is interference, which is the retroactive inhibition, the process of learning or the process of memorizing will be disrupted.

CFTR does not get eliminated, and CF does not exist. However, I know that it is not that simple. In regards to your questions, some studies touch upon ERAD inhibition as a therapeutic tool that deals with diseases related to misfolded proteins. In fact, one of the most outstanding studies is titled “Targeting the ERAD pathway via inhibition of

kill bacteria or, suppress their growth or their ability to reproduce. According to the mechanism of action antimicrobial drugs are work in a several ways: inhibition of cell wall synthesis, inhibition of protein synthesis, inhibition of nucleic acid synthesis, inhibition of metabolic pathway, disruption of cell wall permeability and inhibition of viral enzymes. Also, antibiotic drugs further classified as bacteriostatic or bacteriocidal. Antimicrobial drugs either
