Study of Bacterial Growth and Resistance Level to Certain Antibiotics INTRODUCTION Escherichia coli—better known as E. coli—is a gram negative‚ rod shaped bacteria. It is relatively harmless‚ but can occasionally cause food poisoning. It can also provide Vitamin K2. It prevents the establishment of pathogenic bacteria‚ and is associated with or found in the intestinal organ. The antibiotic that E. coli is resistant to is Penicillin. Bacillus subtilis—better known as B. subtilis—is known as

learns to adapt to the unfamiliar nutrient-filled environment it is placed. The second phase is called the log phase. During the log phase‚ the bacteria experiences exponential growth. Nutrients are metabolised at maximum speed until all of the nutrients are entirely consumed. At this point‚ the bacteria starts to limit growth. The third phase is the stationary phase and is a result of depleted nutrients. This is the phase where the bacteria ceases its metabolic activities. The final phase is simply

David Kennedy Bio 210 Lab Report 1 10/11/13 Microbial Growth Background Information: This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately

P.C.H. Brouardel. Anyone well educated in the science field can say that these words pretty much sum up what it is to be ethical and how to act in a laboratory. There are also three important aspects to follow according to the American Society of Crime Laboratory Directors Laboratory Accreditation Board in order to be seen as a performing laboratory with professional and ethical conduct. These qualities are professionalism‚ competency and proficiency‚ and clear communications. Unfortunately for many

Introduction: Bacteria need specific living conditions to survive. The ideal conditions for bacterial growth is a warm‚ dark‚ and damp environment. This provides the maximum effectiveness for bacterial growth. The areas in our school that contain the most bacteria would be the water fountains because the bacteria from our mouths drop off on to it when we drink from it‚ and because water fountains are not regularly washed in comparison to weight equipment. Water fountains also provide a warm damp

INTEGRATED PRODUCT DEVELOPMENT AND STRATEGIES ASSIGNMENT – I S.SATISH BABU 11MD34 RAPID PROTOTYPING Rapid prototyping is the automatic construction of physical objects using additive manufacturing technology. The use of additive manufacturing for rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software‚ transforms them into thin‚ virtual‚ horizontal cross-sections and then creates successive layers until the model is complete. It is a

Former Massachusetts State Crime Lab chemist‚ Annie Dookhan‚ has been indicted on twenty-seven counts of tampering with evidence‚ perjury‚ and obstruction of justice after a legal fallout that has jeopardized thousands of drug cases (Smith). Dookhan admitted to “dry-labbing” (distinguishing a sample is a narcotic based on appearance instead of actually testing)‚ altering test results‚ and “deliberately turned a negative sample into a positive for narcotics a few times”. Another way in which she tampered

Examine the reasons for changes in divorce rate since 1970 Since the 1960’s divorce rate began to increase dramatically but the biggest rise in divorce rate was in 1972 when it doubled and was 120‚000. The divorce rate continued to rise and in 1993 reached its peak at 180‚000. There has been explanations for the rise in divorce which are: secularisation‚ changes in law‚ divorce had become cheaper and also changing attitudes in society especially with women as they had begun to receive more rights

Humanities – Cultural Studies Research Paper Modern China (Paper) How China’s Rapid Economic Growth Affects Their Environmental Condition In the last three decades‚ the Chinese people have drastically transformed their country from a once poverty stricken country into an economic powerhouse. However‚ the impact this growth has had on their environment is quite appalling. The Republic of China’s rapid economic growth has negatively affected the countries’ environmental status. Increased emissions
