Escherichia coli also known as E. Coli‚ is a type of bacteria which thrives in polluted water. Many people will come in contact with this type of bacteria in their lifetime. In fact‚ E. coli is normally found in the intestine of humans and animal where it plays a significant role in the digestive system. The bacteria can also be found in raw meat and uncooked vegetables as well as polluted water. Most of the strain of E. coli are harmless therefore they will not cause illness if consumed. “One of

UNKNOWN LAB REPORT UNKNOWN NUMBER 54 Ron Williams 7-28-05 Bio 205 Prof. Curlee Fall 2005 Purpose There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory

a sample of contaminated dirt by running it through a series of identification techniques. Some of these techniques were simple staining‚ gram staining‚ and isolation techniques. The hypothesis of this experiment was that the bacterium is of the bacillus family due to the rod shape. Due to multiple complications with the PCR‚ a new hypothesis couldn’t be formulated. Methods: In this experiment‚ a 1 gram sample of contaminated dirt was taken and mixed with 100 mL of sterile water then shaken. After

Imperata cylindrica as an Antibacterial Agent for Escherichia coli INTRODUCTION a. Background of the Study We all know that bacteria are everywhere. Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. One example of bacteria is E .coli is a bacterium that is commonly found in the gut endotherms. E. coli and related bacteria constitute about 0.1% of gut flora‚ and fecal-oral

accumulate data on the growth of Escherichia coli (E. coli) and to monitor how it grows under certain conditions. It has been demonstrated that the levels of glucose and dissolved oxygen were found to affect the rate of growth of E. coli proportionally with a lack of oxygen resulting in the lowering of the pH. In this experiment the growth of E. coli was studied at constant temperature (37 0C) at which it grows ideally. Experimental results for the growth of Escherichia coli showed good agreement with

conclusion‚ different staining techniques are used to determine the presence of certain exterior structures of the bacteria like the cell envelope or just to identify the basic shape and size of the microbe. In this experiment‚ the microbes E. coli‚ Bacillus sp and an unknown microbe from petri dish 1 were categorised as gram negative or gram positive and their shape was identified. These staining techniques are the correct way to identify the shape and size of microbes.

Amanda Lab Report 1 Microbiology Laboratory Title – Differentiating Organisms using the Gram Stain Introduction The experiment conducted was based upon the known attributes of two different groups of bacteria‚ those that are gram positive‚ and those that are gram negative. Using a specific staining procedure‚ it is possible to differentiate the two types under a microscope The gram stain method of differentiation is possible because of differences in the cell membrane between the two categories

Aseptic technique Michele Pearson‚ Leah Christine Silver‚ and William Jarvis Purpose Aseptic technique is employed to maximize and maintain asepsis‚ the absence of pathogenic organisms‚ in the clinical setting. The goals of aseptic technique are to protect the patient from infection and to prevent the spread of pathogens. Often‚ practices that clean (remove dirt and other impurities)‚ sanitize (reduce the number of microorganisms to safe levels)‚ or disinfect (remove most microorganisms but not
