Proteobacteria Essays

Exponential Growth of E. coli Escherichia coli, also more commonly known by the name E.coli, is a commonly found in the large intestines of warm-blooded organisms. The strains of bacteria that are found in the body are not harmful and can actually aid the body in things like digestion. E.coli, like a lot of bacteria, have a growth stage that can be expressed exponentially in both an equation and on a graph. In order to calculate and predict the number of E. coli bacteria cells growing on a plate

Large relative amounts of Firmicutes (40.7 ± 15.9%) and Bacteroidetes (39.5 ± 19.9%) were found, followed by Proteobacteria. According to dietary patterns, the proportion of Firmicutes (Figure 1, panel A) was lower and that of Bacteroidetes was higher in the strict vegetarian group (Figure 1, panel B) when compared to lacto-ovo-vegetarians and

Pseudomonas aeruginosa are rod-shaped, monoflagellated bacteria. They are in the domain Bacteria, phylum Proteobacteria, class Gamma Proteobacteria, order Pseudomonadales, family Pseudomonadaceae, genus Pseudomonas, and species P. aeruginosa. They range in size from 1-5 micrometers in length and 0.5-1.0 micrometers in width. There are 3 possible colony morphologies that can be seen and these depend on where the bacteria is taken from. P. aeruginosa from water and soil are typically small and rough

After this, Proteobacteria and Actinobacteria phyla were identified to be common. With all the surface swabs collected, there was a total of 25 different genera identified and 63 species founded. From human and environmental origin, is composed of majority of these bacterial

As humans, we can think of ourselves as capsules that encase trillions of bacterial cells. A vast majority of bacterial cells line our gastrointestinal tract (GI). The population of cells within the gut may be referred to as a microbiome, microbiota, and/or gut flora. The functionality of microbes is essential to human health. Moreover, it’s what determines how our bodies will function with respect to health and disease. Alike all natural ecosystems, animal (including humans) and microbial populations

Where is the digestive system located? The digestive system is a continuous tube that is composed of a complex series of organs and glands which extends from the mouth to the anus through the thoracic and abdominopelvic cavities. It is responsible for breaking down food into forms that can be absorbed and used by the body’s cells. It also absorbs water, vitamins, and minerals, and eliminates wastes from the body. (psio book) List the main types of microbes present. Substantial numbers of microbes

According to the series of test that my group ran for our unknown specimen, we had a match with the bacteria known as Alcaligenes Faecalis. This bacterium belongs to one of the major group of gram-negative bacteria (Phylum Proteobacteria). Alcaligenes Faecalis (Genus, species) is a rod shaped (bacillus), 0.5-1.2 x 1.0-3.0 µm, round with scalloped margin (colony configuration growth), motile (with one to nine peritrichous flagella), gram-negative, non-fermentative bacteria, obligate aerobic, having

There are two kinds of cellular life forms on Earth.Endosymbiotic theory, is a theory of the origin of eukaryotic cells from prokaryotic organisms, first thought of in 1905 and 1910 by the Russian botanist Konstantin Mereschkowski, and gone further into and substantiated with microbiological evidence by Lynn Margulis in 1967.The Endosymbiotic Hypothesis wasn’t developed overnight by a single scientist. The combined work of several researchers over a century of experimentation has led to the Hypothesis

food production, medicinal research, health, ecology and biotechnology. In this essay I will be talking about the genus pseudomonas in particular. The basic few things to know about the pseudomonas bacteria is that it falls under the class of proteobacterias, belongs to the family of Pseudomonadaceae and is a Gram negative bacteria. It is rod shaped in structure and measures 0.5 to 0.8 µm by 1.5 to 3.0 µm. This bacteria is useful to microbiologists and

(HUS) happens once microorganisms enter the system and release a poisonous substance that destroys red blood cells. Patients with hemolytic uremic syndrome often have dysentery. The syndrome is deadly (Galanakis et al., 2002; Butler, 2012). Enterococcus: Enterococcus is the massive group of carboxylic acid microorganism of the phylum Firmicutes. Enterococci are Gram +ve cocci that generally occur in pairs (diplococci) or short chains. Enterococci are facultative anaerobic organisms, i.e., they're

Chapter 1: Hydrothermal vent habitats As light penetration at depths below 300 meters is inadequate to support photosynthesis, ambient seawater temperatures below 1000 meters lie between 1 and 5⁰C and hydrostatic pressure increases with 1 atm for every 10 meters of water depth, for a long time the deep sea was not regarded to be a very habitable environment (van Dover, 2000). However, since the discovery of hydrothermal vents in 1977 this view has drastically changed (Corliss et al., 1979; German

The goal of this experiment was to see which forms of turkey would yield the most microbes. Our hypothesis was that the turkey exposed to more was going to yield the most microbes. My prediction was that the raw chunk turkey and the non-organic sliced turkey was going to have the most microbes. To my surprise, the Inspirations deli turkey from Hannaford had the most microbes in both experiments. Experiment 1 began with obtaining 5 different samples of turkey that had all been cooked and prepared

Serratia: Serratia’s a group of gram (-negative), facultative anaerobic, rod-shaped bacteria of the Enterobacteriaceae family. Serratia are most common and pathogenic of the species within the genus, S. marcescens, is often the sole infective agent and frequently causes health facility infections. S. marcescens is often found in showers, bathroom bowls, and around wetted tiles. The bacterium is associate timeserving, human infective agent, capitalizing on its ability to make integrated surface communities

1. Introduction Bacteria have evolved several different mechanisms to enable them adapt successfully to their environment. All organisms have intrinsic genetic determinants that are expressed when challenged with different stress factors. Examples of such environmental stressors include antibiotics, chemicals, ionizing radiation, high salinity, extreme hydrostatic pressure, extreme temperatures and heavy metal stress, among others. When faced with single or multiple challenges, a series of transcriptional

TABLE 1 - Particle Size Range (micrometers).5 3. RESULTS AND DISCUSSIONS Experiment A shows that the compound present in the dust sample is Sodium Nitrate. Experiment B shows the dust is inhalable and can directly get to the lungs. From the oxidation state of nitrogen, Nitrate is the most oxidized form of nitrogen present in the environment. It accounts for the majority of the total available nitrogen in surface waters (Environment

Pseudomonas aeruginosa and Chronic Lung Infection of Cystic Fibrosis Patients Valerie R. Vorndran Pueblo Community College   Abstract Cystic Fibrosis is a genetically inherited autosomal disease that affects the ability to clear mucus from the airway. Mucus accumulation in the lungs and airway increases susceptibility to opportunistic pathogens such as, Pseudomonas aeruginosa. Airway bacterial infection and eventually chronic lung infection is the primary cause of death in people with CF. P. aeruginosa

reoccur after treatment some individuals are diagnosed with chronic CDI that can last for an unknown amount of time. Studies have shown that individuals with reoccurring or chronic CDI typically have low levels of Bacteriodetes and abnormally high Proteobacteria and Verrucomicrobia. However, after a successful fecal microbiota transplant these species deficiencies are

GAIRANOD, Princess Jeanne R. BS Biology, 2011 – 37638 Synthesis Paper: Shigella flexneri The genus Shigella includes four different species – Shigella boydii, Shigella dysenteriae, Shigella sonnei, and Shigella flexneri. Several serotypes occur for each species based on O - antigen variations (Jennison & Verma, 2004; Morona, et al., 1995). Members of the genus are gram-negative, highly infective facultative intracellular pathogens, recognized as etiological agents of bacillary dysentery (shigellosis)

ntroduction: Soils are a naturally occurring cover of the earth's surface and come in three different states; solids, liquids, and gases. The solid states contain dead biological materials and as well as geological. The liquid states contain water and the gas states contains soil pores present in the air. Soils are the foundation of all land ecosystems and are home to many varieties of bacteria, fungi, insects, archaea, annelids, plants and algae. These organisms that are found in the soil provide

Is there a difference in the boring mechanism of different Osedax species and has the mechanism been consistent over time? Bioerosion is an important process in nature because it changes the present environment. Typically, it is used to describe the process of breaking down a hard substance in the ocean by a living ocean. The bioerosion of coral into small particles results in the fine sand that show up on our beaches. Different organisms use different mechanisms for removing the substrate. Parrotfish
