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

Humans and Microorganisms Humans will always use microbes. They occur in everyday life‚ everyday without fail. We use them for little things like inside to food production. However they are the root of some very unpleasant conditions like cholera and tuberculosis. To begin with‚ nearly every human being with consume food that has been produced using microbes or its self is a microorganism. Mushrooms are a good example of this as they are fungi which are eaten across the globe. You do need to

A Brief History of Antibiotics‚ Antibiotic Resistance‚ and Antibiotic Alternatives Antibiotic Resistance and Alternatives Antibiotics have been commonly‚ though mistakenly‚ thought of as the ultimate cure‚ for almost all illness‚ for over half a century now. However‚ the intended use of antibiotics is for the treatment of bacterial infections and diseases. Viruses or fungi-related illnesses will not be affected by antibiotics. This misunderstanding of the use of antibiotics has led to overuse

No-Calorie Powder May Substitute for Food’s Fat George E. Inglett of the U.S. Department of Agriculture’s Biopolymer Research Unit in Peoria III invented a no-calorie fat substitute called Z-Trim. It is a mix of crushed fibers made from the hulls of grains. It can replace the fat and some of the carbohydrates in foods such as chocolates‚ brownies‚ cheese‚ and ground beef. He spent three years trying to perfect Z-Trim to be smooth because he made it out of tough hulls of corn‚ oats‚ and rice

The discussion on Patrick Dismuke’s condition concentrated on his incapability to improve. After reviewing his symptoms and considering possible scenarios resulting from certain kinds of treatment‚ such as the tube that delivered nutrients into his veins that "broke the barrier between blood and air" and became "a bacteria-laden Trojan horse‚ opening the door to infection"‚ we attempted to come to a consensus on what would constitute a quality life‚ as deliberated among the committee. We took into
