Bacteria Essay Examples

Probiotics are live microorganisms thought to be beneficial to the host organism. According to the currently adopted definition by FAO/WHO, probiotics are: “Live microorganisms which when administered in adequate amounts confer a health benefit on the host”. Lactic acid bacteria (LAB) and bifidobacteria are the most common types of microbes used as probiotics; but certain […]

This report discusses an experiment that was done to demonstrate the effects of lysozyme on populations of Gram positive and Gram negative bacteria. Bacteria have a cell wall composed of peptidoglycan that gives the wall its strength. Gram negative bacteria have and extra component of lipopolysaccharide (LPS), that is stabilized with magnesium ions, to their […]

Introduction The fundamental components of all living beings are cells. Cells offer structural support, absorb nutrients, and convert energy. They also possess specific functions and genetic material for replication. Furthermore, cells function as metabolic compartments where a variety of chemical reactions occur. There are two categories of cells: eukaryotic and prokaryotic. Both prokaryotic and eukaryotic […]

Introduction Transformation is the transfers of virulence from one cell to another, through the transferring of genetic material. It was originally postulated in 1928 through the works of Federick Griffith, a British microbiologist. Griffith observed that the mutant form, non-virulent form, of the bacteria Streptococcus Pnumoniae could be transformed into the normal, virulent form, when […]

Bio 205 Workshop 2 Bacteria Purpose of Bergy’s Manual: based on ribosomal RNA sequences, which presumably reflect phylogenetic (evolutionary) relationships. Used for the identification of prokaryotes. 2nd edition on classification of prokaryotes. 4 Tests/ Parameters that are evaluated to classify bacteria are: procedure’s that determine an organism’s ability to ferment carious carbohydrates; utilize various substrates […]

Microbiology, which involves the study of microorganisms that cannot be seen with the naked eye, encompasses various techniques such as aseptic technique, pure culture technique, and microscopic observation. Microbiologists isolate specific microorganisms from wild populations to examine them. Initially centered on harmful microorganisms leading to disease or spoilage, microbiology now acknowledges the significant roles of […]

The development of dyes to stain microorganisms was a significant advance in microbiology. Stains serve purposes such as it differentiate microorganisms from their surrounding environment and it allows detailed observation of microbial structures at high magnification. (http://insist. Back. Wise. Deed/, 0 2006-2013 Microbiology Laboratories) Sexagenarians (2005) defined staining as the method of artificially producing color […]

Microbiology is the study of microorganisms or microbes, which are tiny life forms that cannot be seen without magnification. These microorganisms are found everywhere and have a significant impact on the planet. The discovery made by Englishman Robert Hooke in 1665 of “little boxes” or “cells” in a slice of cork through the microscope is […]

What is a license? It is an award given to you for your effort of learning something. You go to a training school, after you pass whatever it is, you apply for a license that gives you right to use your knowledge you gain. So, the vermin say that freedom is not an award given […]

The identification of the active antifungal substance that inhibits spore formation and causes abnormalities in Aspergillus niger structures has been accomplished. Fungal growth frequently leads to the presence of toxic mycotoxins, such as ochratoxin A (OTA). Key words: Aspergillus niger, Streptomyces noursei, ochratoxin A. According to Miller (1994), mycotoxins present a significant health hazard for […]
