Water And Milk E Coli
985 wordsBiology Escherichia coli Escherichia coli Escherichia coli is an Enterobactericeae bacteria. This family name is derived from the fact that nearly all species in it, more or less, constantly inhabit the intestines of humans and animals. Because of its widespread presence in the environment and its ability to promote disease in humans, one of the most prominent members of this family is the species Escherichia coli. This bacterium is so common that its name has come to describe all similar bacter...

Different From Other Bacteria
4,548 wordsBACTERIA (Gr. bakterion, "little staff"), group of microscopic, unicellular organisms that lack a distinct nucleus and that usually reproduce by cell division. are tiny, ranging from 1 to 10 micrometers (1 micrometer equals 1/25,000 in), and are extremely variable in the ways they obtain energy and nourishment. They can be found in nearly all environments-from air, soil, water, and ice to hot springs; even the hydrothermal vents on the deep ocean floor are the home of sulfur-metabolizing bacteri...

Positive Bacteria
1,223 wordsIntroduction: The purpose of this experiment is to isolate and differentiate between two bacterial species using Gram's stain, microscope visualization and different biochemical tests. Bacteria can be classified and differentiated based upon different morphological characteristics, staining reaction, nutritional needs, cultural characteristics, physiology, cellular chemistry, and biochemical tests results for specific metabolic end products. Identification of unknown bacteria is useful in many s...
