Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations

between a gram positive bacteria and gram negative bacteria is the differences in cell wall composition. Prokaryotes known as eubacteria have three basic forms: rods‚ cocci and spiral. The bacterial cell wall is the single most important contributor to cell shape. In addition to shape of cell wall‚ presence or absence of flagellum‚ and if present‚ positions of flagellum‚ the eubacteria can be classified according to Gram Stain. First and foremost‚ gram positive bacteria are by and large dark

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

My journey to the unknown started about three weeks before the end of my microbiology class at Brunswick Community College. This journey started out with a media plate cultured with an unknown species of bacteria. I was then instructed by my professor to use all of my previous knowledge to identify the unknown bacterial pathogen. This lab led me to master my skills of using the Gram stain‚ testing for catalase‚ testing for coagulase and using the oxacillin screen. Now I am going to take you with

Bacteria are the most ancient life forms‚ most bacteria are so small that under a light microscope you can only see them as little dots. Some groups however grow to larger sizes and have spectacular shapes (1). Bacteria are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and the live bodies of plants and animals (2). Bacteria is mostly thought of as a pathogen‚ while it is true that
