Effectiveness of Garlic in Fighting Bacteria Introduction This experiment determined whether garlic was effective in fighting bacteria. This project interested me because garlic is traditionally used in medicine and is known to combat bacteria. Hypothesis If bacteria is exposed to garlic‚ then the garlic will to abolish the Escherichia coli‚ because the Escherichia coli (E. coli) is usually a weak bacteria. Procedure Have three petri dishes prepared with blood agar‚ and three test tubes

time) 3. Clean your surface with disinfectant to sterilise your lab work surface‚ this will prevent contamination but leave the disinfectant to stand up to 4 minutes so it can penetrate the harder capsules of some bacteria. 4. Using a sterile pipette with draw some of your bacteria culture from the bottle making sure you flame the neck of the bottle to keep the procedure sterile. Place what you have withdrawn on to an agar plate. 5. then get your glass sterile spreader out of the packet making

It is thought that archaea and bacteria were diverged early in their existence because of all the dissimilarities between the two groups. Both bacteria and archaea are enclosed in cell membranes. Archaea have a single cell membrane that absences a peptidoglycan wall and also their genetic transcription and translation‚ the two main processes in molecular biology do not show the typical bacterial features‚ but are quite similar to those of eukaryotes. Archaea are more related to eukaryotes‚ even though

Sampling of Gram-Positive Bacteria and Antibiotic Resistance Resting We thought it would be interesting to find out the different bacteria that grow on things we use on a daily basis and the level of antibiotic resistance that those bacteria have. We chose to swab the toilet seat in the MATC women’s bathroom and the ATM machine in the commons area on campus. We were certain the ATM would be dirtier than the toilet seat since the bathrooms get cleaned every day. The first step we took in testing

Fermented food‚ enjoyed across the globe‚ conveys health benefits through lactic acid fermentation. The fermentation process can transform the flavor of food from the plain and mundane to a mouth-puckering sourness enlivened by colonies of beneficial bacteria and enhanced micronutrients. While fermented food like yogurt‚ sauerkraut and kefir are well-known many other lesser-known foods also benefit from the lactic acid fermentation process. Indeed‚ virtually every food with a complex or simple sugar content

Bacteria and Viruses Breann Johnson COM/155 03/17/2013 University of Phoenix Bacteria and Viruses Almost 56‚000 people are hospitalized each year‚ and over 1‚300 die because of food borne bacteria and virus microbes. Bacteria and viruses are tiny microscopic pathogens that can cause infectious disease‚ or even result in death. “Infectious diseases remain a major cause of death‚ disability‚ social‚ and economic disorders for millions of people around the world.

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

Botulism Botulism is a bacterial disease most often linked to un-sterile canned foods. It can be rather serious‚ as it has the potential to paralyze the respiratory system and thus cause death. The bacterium is named Clostridium Botulinum‚ it is a gram-positive and anaerobic pathogen. The morphology consists of rod shaped spores. The toxin is widely used in cosmetic injections‚ also known as Botox‚ to decrease wrinkles in the skin. Though Botulism is mainly linked to canned foods

were measured and recorded. A hypothesis that was formulated before experimenting was‚ “If the type of disinfectant is Mouthwash‚ then it will allow for the least amount of bacteria growth because the chemicals present in Mouthwash combined with the acidic environment it bring will make it very hard to allow for any bacteria growth”. The independent variable in this experiment was undeniably
