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
Identification 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
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
Vinegar can be defined as a condiment made from a variety of sugary and starchy materials by alcoholic and subsequent acetic fermentation. It is in simple words, an alcoholic liquid that has been allowed to sour (Unknown, 2011a) Vinegar can be produced by different methods and from a variety of diluted alcohol products, the most common being, wine, beer and rice. Wine (white, red, and sherry wine), cider, fruit musts, malted barley, or pure alcohol are used as substrates. Vinegar production ranges
collected from the waste water treatment plant located Apphughar, Visakhapatnam. This wastewater treatment plant is a 25MLD which receives raw sewage wastewaters from domestic uses from surrounding the city. The physico chemical parameter analysis reports were given in the Table 4.7.1.

Unknown Number 16 – Salmonella typhimurium Cindy Chai Rutgers University Microbiology for the Health Sciences Abstract This lab report was performed to identify the unknown organism, number 16, through various laboratory tests and techniques. The laboratory tests generated some critical results that suggested the unknown culture was Salmonella typhimurium. Some of the tests that led to the identification of the unknown organism included: the EMB agar plate that resulted as negative for lactose
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, found naturally in bacteria, can be used to cut DNA fragment at specific sequences, while another enzyme, DNA ligase,
close association with animals. The Worldwide, reported incidence of human brucellosis in endemic disease areas varies widely, from 200 per 100,000 population. Egypt, the Islamic Republic of Iran, Jordan, Oman, Saudi Arabia, and Syrian Arab Republic reports a combined annual total of more than 90,000 cases of human brucellosis (Awad et al.,1998). The low incidence reported in known brucellosis-endemic areas may reflect the absence or the low levels of surveillance and reporting (Mc Dermott et
still associated with major problems like: 1. Possibility of development of immunotolerance to the vaccine protein or peptide. 2. Constancy of dosage form is different in every plant, fruit and every generation. 3. Stability of vaccine in fruit is unknown. 4. Some food cannot be consumed raw and needs cooking which weakens the protein content in it. 5. Selection of the best plant is difficult. 6. Evaluating dosage requirements is difficult. 7. Glycosylation pattern of plants and humans is different
ANORECTAL ABSCESS AND FISTULA Anorectal abscesses and anal fistulas are disease processes that have their basis of understanding and treatment firmly rooted in the anatomic design of the anal canal. The potential for disastrous complications is real. Careful, thorough, and meticulous care in the diagnosis and treatment of fistulous abscesses will result in successful outcomes in most cases. Perirectal and perianal abscess are commonly encountered problems in surgical practice. Timely
