Macy Gagne 12/6/14 Microbiology 83414 Angelo Kolokithas Streptococcus pyogenes There are trillions of bacteria on earth. It is hard to believe that something so small can be so destructive. Bacteria replicates so fast that small symptoms can soon turn way worse, sometimes can even cause death. In fact bacterial infections are the number one cause for death in the United States in young children and elderly adults (Streptococcal Infections). The unknown I was given was unknown number four. The tests

A critique of “Into the unknown” published by the economist (November 13, 2004.) Fear of losing jobs to offshoring (rise in unemployment), but computers and technology may take these jobs anyway. “Has the machines in its last furious manifestation begun to eliminate workers faster than new task can be found for them?” Article says not to worry. The United States has experienced an increase in the offshore outsourcing (offshoring) of jobs in the service industry. Although offshoring is common in

size, unique things found in each one, etc.). Bacillus is defined as any of a group of rod-shaped, gram-positive, aerobic or (under some conditions) anaerobic bacteria widely found in soil and water and they frequently occur in chains. Escherichia is a genus of Gram-negative, non-spore forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae. In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a

Madeline M. Westrick Unknown 2 Unknown Lab Report INTRODUCTION In this study, each student was assigned a different unknown bacterium, with the task of identifying it correctly. Unknown 2 was Streptococcus pyogenes. S. pyogenes is gram-positive cocci that can result in human ailments that are classified as Streptococcal A infections, such as impetigo, cellulitis, erysipelas, and scarlet fever. The allotted testing time given was a total of four laboratory periods, or two weeks total. MATERIALS

12:30PM – 3:30PM Unknown 6: Micrococcus Luteus Introduction: This lab requires us to learn about cultural, morphological and biochemical characteristics that are used in identifying bacteria. These characteristics and unique aspects can be observed by learning and using the various different tests and techniques, which is the main purpose here, and can help pinpoint the identity of the unknown organism. Each student will receive a slant containing one species of bacteria. The assignment is

differentiate two types of bacteria that were unknown. Gram staining is a method that is used by many scientists in order to identify unknown bacteria’s via the unique physical and chemical characteristics of their cell walls. In a gram test a bacteria can either be gram positive or gram negative. The Gram-positive bacteria have an intricate set of amino sugars which we call peptidoglycan that form a thick cell wall around the plasma membrane. On the other hand, Gram-negative bacteria have an uncomplicated

Abstract In this experiment an unknown gram-negative sample was obtained randomly to identify the possible microorganisms. Using comparative analysis several biochemical tests were performed to determine which bacterium out of the six potential unknowns was given. The biochemical tests carried out included; triple-sugar iron agar (TSIA), sulfur indole motility (SIM), citrate, urease, gelatinase, methyl red (MR) and voges-proskaeur (VP). In order to determine the microorganism characteristics the

Unknown Laboratory Report Sarah Mansfield Biology 203 Professor Lana November 19, 2014 INTRODUCTION Microorganisms are the earliest forms of life and most have thrived since the early birth of the planet. They have evolved into many different forms of life such as animals, humans, and plants. While some microorganisms impact life in a positive way by sustaining life, others cause disease and even death (Nester, et al. 2012). Prokaryotes are one of the earliest
