Antimicrobial Properties of Plants A plant with antimicrobial properties means that it destroys or inhibits the growth of bacteria and fungi. Aim: our aim was to see weather or not garlic‚ mint and grass contained antimicrobial properties and if they did how effective they were we were trying to see weather the bacteria will grow around the different plants. Control Test: As a control test what we did was‚ we dipped a paper disc into the alcohol solution we used to dissolve the plants; the

Scientist Louis Pasteur’s work not only saved but also protects millions of people from disease every day. His scientific achievements sparked the early development of the food safety industry. His most noted achievement was the birth of germ theory. Initially‚ Pasteur was asked to examine why alcohol becomes contaminated during fermentation. According to his research Pasteur stated that bacterial organism were responsible for souring the alcohol. This discovery evoked him to look into finding where

In this review we will learn a lot of things about the effects of radiation in plants and some information about the plants and radiation. So as I go on my research I found out that‚ in moving from the water to the land‚ several living creatures had to subdue the number of problems. It must include the fortification against reproduction‚ fluid and nutrient transport‚ desiccation and ultraviolet radiation. So plants started from algae‚ it has been found in a long time photosynthesizing bacteria could

Quantification of Microbes in Milk and Water Naomi Hall 10/20/14 BSC 381L H003 Group: Megan Baker‚ Katie Coe and Meagan Williams Abstract Coliforms are gram negative bacteria commonly found in the intestines of birds and mammals and are the most widely utilized indicators of fecal contamination. The purpose of this experiment was to test various water and milk samples for the presence of coliforms‚ specifically fecal coliforms. It was expected that fecal coliforms would be found in all

Penicillin V (generic name) is an antibiotic drug largely used in pharmacy practice‚ belonging to the Penicillin group of drugs. There are many other drugs that are also in the Penicillin family such as amoxicillin‚ ampicillin‚ carbenicillin‚ dicloxacillin and oxacillin. These are used in patients to treat bacterial infections. (https://www.drugs.com/penicillin.html). Penicillin was discovered by chance by Alexander Fleming in 1928 when Penicillium spores had been introduced to the culture medium

Why are semi-solid media used to test for motility? D. Why might it be difficult to observe motility in a wet mount? E. Why is it important to use a needle rather than an inoculating loop when inoculating a motility tube? F. For which of the organisms on the wet mount‚ if any‚ were you able to observe motility? G

Bonnie Bassler claims that bacteria although simple have complex systems that they use to communicate with each other to coordinate. This is crucial to humans because Dr. Bassler considers humans to be 90-99% bacterial. Dr. Bassler states we have about one trillion human cells but we have about 10 trillion bacterial cells that either live in or on humans. The number of bacterial genes in those cells outnumber humans by 100 times since humans only have 30‚000 genes. These bacteria share a mutualistic

In medical facilities it is necessary to equips materials and surfaces with a high level of hygiene using antimicrobial agents to protect them against bacteria and other micro organisms to prevent infections caused by bacteria and contribute significantly to reduce health costs. Benefits of nanoscale coatings in this sector include long lasting antimicrobial effect‚ constant release of the active substance‚ effectiveness against bacteria and other micro-organisms‚ no chemical impurities‚ easy processing

In September 1928‚ Fleming returned to his laboratory after a month away with his family‚ and noticed that a culture of Staphylococcus aureus he had left out had become contaminated with a mold (later identified as Penicillium notatum). He also discovered that the colonies of staphylococci surrounding this mold had been destroyed. He later said of the incident‚ "When I woke up just after dawn on September 28‚ 1928‚ I certainly didn’t plan to revolutionize all medicine by discovering the world’s

Louis Pasteur was a pioneer of immunology. He was born in 1822. He grew up in the city of Dole‚ France. When he was young most of his teachers felt that he was slow and that advancing his education was not what the future held for him. His father was a leather tanner. His teachers felt that he should carry on that trade. He however had one teacher that believed in him. He then advanced his education and studies on to Paris‚ France. Louis Pasteur was an extraordinary man. While advancing his
