Science Timeline In the early 1860’s the French beverage industry was thriving. Pasteur was called upon to tackle some of the problems that were plaguing the industry. The special concern was the spoiling of wine and beer‚ which caused great economic loss and tarnished France’s reputation for fine vintage wines. He noticed that when aged properly‚ the liquid contained little yeast cells. But when the wine turned sour‚ he was a proliferation of bacterial cells which were producing lactic acid

The effect of toothpaste to oral bacteria VS the effect of mouthwash to oral bacteria Problem: Bacteria in ones’ mouth causes many problems for oneself in the future. For example‚ gum diseases‚ bad breath‚ etc..‚ Toothpaste and mouthwash is promised to kill most of the bacteria in one’s mouth‚ but which is more effective at killing the bacteria and preventing future problems? This experiment and research is going to prove which is more effective at killing oral bacteria

The human body is rich in bacteria‚ in fact it has more bacteria than cells. Bacteria can be helpful‚ but can be extremely harmful as well. The harmful bacteria have acted as parasites towards humans since the initiation of mankind. Campylobacter Jejuni‚ ranked as a subspecies of the Campylobacter species‚‚ is the most common form of bacterial gastroenteritis in third-world countries. In fact‚ it causes 5-14% of diarrhea-related diseases worldwide‚ resulting in hospitalization. For instance‚ in the

A living system grows‚ provides for itself and reproduces by itself. The coolest thing about a living system is that it is composed of non-living molecules and atoms. Biochemistry is basically that the pursuit of knowledge of what goes on chemically within a living system is classifies as such. Although there are thousands of different types of molecules in a cell‚ only few are bimolecular like the four common macromolecules and many more. Proteins and carbohydrates are important factors of our food

Two different types of procedures were carried out over the course of this experiment: tube inoculation and plate inoculation. We started with plate preparation. Three different lysogeny broth‚ or LB‚ agar plates were prepared for E. coli growth every other week: a control where water was used‚ one for triclosan‚ and one for streptomycin. Using an inoculation loop‚ E. coli was transferred from the test tube to the agar plate. This was done to each plate twice‚ creating a grid-like pattern of bacteria

The Kirby-Bauer Antimicrobial Susceptibility Test Read section II of chapter 26 in your lecture textbook for background on chemical antimicrobial control (for background)—pages 762-763. Introduction Today you will perform a frequently used procedure called the Kirby-Bauer Antimicrobial Susceptibility test (disc diffusion technique). Each group will inoculate his/her own plate of Mueller-Hinton agar with an assigned culture. To that inoculated plate‚ you will then aseptically add sterile

My journey to the unknown started about three weeks before the end of my microbiology class at Brunswick Community College. This journey started out with a media plate cultured with an unknown species of bacteria. I was then instructed by my professor to use all of my previous knowledge to identify the unknown bacterial pathogen. This lab led me to master my skills of using the Gram stain‚ testing for catalase‚ testing for coagulase and using the oxacillin screen. Now I am going to take you with

TITLE OF PROJECT: Effects of Chemoattractants of Pseudomonas Aeruginosa Through a Capillary Tube. PROPOSED COST: $1764.90 ABSTRACT: This project will show how strong certain bacteria that are commonly found in biofilms attract to Pseudomonas aeruginosa through a capillary tube. It will test ten bacteria to see which bacteria have more chemoattractants with Pseudomonas aeruginosa . These bacteria are all motile‚ so to come together to form a biofilm‚ they must lose their ways of
