identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully isolated two different bacterial species by examining my MAC and CNA plates. Only

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

What Caused Secession? Before the Civil War began in 1861‚ there were major factors that led to the secession of the southern states. These factors affected the people of America tremendously due to slavery and racial segregation. Three significant factors that led the eleven southern states to secede from the Union were abolitionists (Doc. 5)‚ Kansa-Nebraska Act‚ and the election of 1860 (Doc. 1). During the period of slave existence‚ abolitionists began to rebel against the situation (Doc

BACTERIAL TRANSFORMATIONS USING PVIB II. INTRODUCTION Transformation is the manipulation of a bacterial cell’s DNA in order to alter the cell’s genotype or phenotype by absorbing free DNA from its surroundings. In this lab‚ pVIB plasmid will be used. A plasmid is a segment of DNA that can incorporate itself into the bacterial DNA. Although is not required for growth of the bacterial cell‚ plasmids can provide advantages in stressful environments such as the ability to adapt as environmental

Many of the bacteria that cause common bacterial infection are mutating and therefore gaining resistance. This means that the original antibiotics that were once used to treat these common illnesses are becoming increasing ineffective. This resistance delays treatment as the original antibiotics are ineffective. This can lead to the disease worsening and even death. This means that common illnesses that were once easily treated by antibiotics are no longer so easy to treat. This results in increased

inhibits the enzyme peptidyl transferase. This inhibition results to the prevention of the transfer of amino acid for growing peptide chains which leads to the inhibition of the formation of bacterial protein. (Michigan State University‚ 2011). Chloramphenicol is a broad-spectrum antibiotic. (Hitner et al.‚ 2016). Bacterial microorganisms become resistant by the inactivation of chloramphenicol through the enzyme acetyltransferases. (Rang et al.‚ 2016). Chloramphenicol resistance are very common in Staphylococcus

Abstract: Milk plays a very important role in meeting the day to day nutritional needs and requirements of a human being. It is a fulfilling product which provides the body with all the essential nutrients. In today’s world there is a lot of contamination in each and every food item which is the cause of many diseases spreading in humans. Milk contains a bulk of casein molecules which play a very important role in microbiology and pharmaceuticals. The samples of milk were collected from the market

Ecological Succession Worksheet Name __________________________________ Date ________ Period _______ Succession‚ a series of environmental changes‚ occurs in all ecosystems. The stages that any ecosystem passes through are predictable. In this activity‚ you will place the stages of succession of two ecosystems into sequence. You will also describe changes in an ecosystem and make predictions about changes that will take place from one stage of succession to another. The evolution of a body
