Bacteria‚ algae‚ protozoa‚ helminthes (parasitic invertebrate-worms) and fungi. 2. Multiple types of Professions Using Microbiology: b.

with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work dealt with bacteria‚ which are tiny microorganisms that can only be seen with the help of instruments like the microscope‚ which he invented. II. John Tyndall (Aug. 2‚ 1820- Dec. 4‚ 1893) C. In 1877 Tyndall demonstrated that dust carries microorganisms. He showed that if dust was absent‚ nutrient broths remained sterile‚ even if directly exposed to air. He also provided evidence for the

A General Essay on Bioremediation of Contaminated Soil Dana L. Donlon and J. W. Bauder‚ Professor‚ Montana State University-Bozeman MSSE Graduate Student and Professor‚ respectively Bioremediation is defined as use of biological processes to degrade‚ break down‚ transform‚ and/or essentially remove contaminants or impairments of quality from soil and water. Bioremediation is a natural process which relies on bacteria‚ fungi‚ and plants to alter contaminants as these organisms carry out their

Microbial spoilage There are three types of microorganisms that cause food spoilage -- yeasts‚ moulds and bacteria. Bacteria are round‚ rod or spiral shaped microorganisms. Bacteria may grow under a wide variety of conditions. There are many types of bacteria that cause spoilage. They can be divided into: spore-forming and non-spore-forming. Bacteria generally prefer low acid foods like vegetables and meat. In order to destroy bacteria spores in a relatively short period of time‚ low acid foods must

mary. Science 1972 bioremediation has become greater developed as a means of cleaning up spills of gasoline diesel ‚ heavy metals and other easily degraded petroleum products (National Research Council 1993). Bioremediation refers to the use of microorganisms to degrade contaminants that pose environmental and especially human risks. Due to its safety and convenience it has became an accepted remedy for cleaning polluted soil and water. A widely used approach to bioremediation involves stimulating

subsequent combination of the products with iron produces a black color. A positive test for the bile esculin slant is a completely blackened tube (Lindell et al‚ 1975). A triple sugar iron (TSI) slant is used to identify sugar fermentation in a microorganism; it contains a red pH-sensitive dye that will turn yellow under acidic conditions‚ such as contact with the acidic byproducts of sugar fermentation. The three sugars‚ sucrose‚ lactose and glucose‚ are present in specific concentrations‚ 1%‚ 1%

Louis Pasteur was a chemist‚ turned microbiologist‚ turned veterinary medicine pioneer‚ turned vaccine maker. As a chemist‚ he was originally interested in the light bending properties of certain crystalline solutions. During the course of his study of these solutions he discovered that certain types of solutions were created by biological processes. As he investigated this phenomenon he was led to investigate the field of fermentation where he essentially discovered the aerobic and anaerobic

The field of biotechnology growing at an exponential rate and branches off into several categories. B. Bioremediation is a subcategory of biotechnology that involves microorganisms and the environment. Although bioremediation is primarily established my man‚ it is a fairly natural process using microbes

areas such as: bacteriology‚ virology‚ parasitology and immunology. The goal of microbiology is to increase the specific knowledge of a known microorganism and by extension counter the spread of harmful microorganisms and to learn practical applications of research results. A microbiologist studies the structure‚ metabolism‚ genetics and ecology of microorganisms such as bacteria‚ viruses‚ fungi or algae. A microbiologist also studies in the relationships of these organisms among themselves and how they
