INTRODUCTION Bacteria constitute a large domain of prokaryotic micro-organisms. They are typically a few micrometres in length and have a wide range of shapes ranging from spheres to rods. Bacteria are the most diverse and abundant group of organisms on earth and in favourable conditions bacteria reproduce very rapidly by binary fission, an asexual process whereby a single cell divides into two with identical DNA. Under ideal conditions some bacterial species may divide every 10 to 15 minutes. Within
of Unknown Bacteria Microbiology is the study of organisms that are invisible to the unaided eye. Bacteria are a diverse group of microbes that have the ability to inhabit many different habitats, including soil, food, water, and human bodies (Collard, 1976). Among their beneficial uses is their use in the production of food, alcohol, and antibiotics. Not all bacteria are helpful to humans, however. Medical microbiology is an active field of study which deals with identifying bacteria that can cause
Mixed Unknown Bacteria Lab Report Biology 2460-002 Jamuna Kadariya November 24, 2014 Unknown number: thirty-four I. Abstract There are many types of bacteria and they produce different enzymes. However, some bacteria can produce same enzymes. In order to identify the particular enzymes produce by each bacteria specific test needs to be done. Among various types of enzyme producing bacteria, gram- negative and gram-positive bacteria are given priority in our experiment. There are four main types
Bacteria and Antibiotic Lab Report The purpose of this lab was to identify the possible bacteria discovered in two patients and to test different antibiotics on the bacteria to find the best treatment for each patient. In order to identify the bacteria, we had to Gram stain the bacteria from culture A and the bacteria from culture B, and then observe the bacteria under a microscope. We recorded the shape and color of the bacteria in order to find a possible match with a strand of bacteria. If a
Bacterial Transformation Alyssa Krajnik Lab TA: Qi Deng Lab Time: Thursday 4:30 Report Submitted: 09 APR 2015 Abstract: The purpose of this experiment was to observe the process of transferring genes from one organism to another using the aid of a plasmid. However, the results obtained from the experiment illustrated that the data collected was not reliable. The results indicated that not enough bacteria were transferred to the agar plates. Because of the errors that occurred in the experiment
September 29, 2014 BIOL 240 Lab Report Gram Stain Introduction Various methods are used to identify unknown bacteria. A popular method to determine unknown bacteria is called a Gram Stain. A stain is coloring a specimen with dye. A Danish physician named Hans Christian Gram developed the Gram stain method in 1844. He studied at the University of Copenhagen and became a professor of Medicine. When differentiating between two types of pneumonia, he found that most bacteria are either Gram-positive or
Final Diagnosis Report- Sue Smith’s College Outbreak Introduction: 18 year old Sue Smith has a slight fever, with a pounding headache and she feels extremely tired. Some of her friends have similar symptoms and hopes it’s just a cold, but after days she is feeling worse and her neck feels extremely tight. Just going of her symptoms we’d though she have the Flu, Influenza, or just a simple cold. By using bioinformatics, which is a field of science that combines biology, computers, and information
A: Summary The report is about the lab-made burger patty. Technology has reached a point, where scientists are able to make a burger patty in the lab. There are some issues that follow with this technology. One of them is the price of the burger patty is $300.000, which makes it impossible for a normal consumer to buy it. An another issue such as the taste will also come in to play, where it has a taste that satisfies the people and also the nutrients in the meat. Besides the “ick-factor” that this
Objective: This lab was done to help understand restriction enzymes and how they work. As well as comprehend the correlation between these enzymes and DNA Fragments. This lab was conducted to estimate the size of unknown DNA fragment thru agarose gel and electrophoresis. Background: A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence. Restriction enzymes
Specific goals were to achieve 10-12% acidity using constructed lab scale production facilities and to characterize the species of vinegar bacteria used in acetification. Vinegar is the product made from the conversion of ethyl alcohol to acetic acid by a genus of bacteria, Acetobacter. Therefore, vinegar can be produced from any alcoholic material from alcohol-water mixtures to various fruit wines. Its colour and
