Experiment 6: Microbial Cultivation Objectives: To successfully cultivate microorganisms from different sources to medium. Materials: Broth‚ Agar‚ Sterilized cotton swab‚ Procedure: 1) Get your broth with cotton swab inside containing your bacteria. 2) Remove the cotton and flame sterilize the mouth of the testtube. 3) Get your cotton swab inside‚ flame sterilize again the mouth of the testtube then plug it with cotton. 4) Grab the inverted plated media and flame sterilize the

INTRODUCTION: In this laboratory exercise explore the differences of microorganism and continue our use of specialized media and use some biochemical testing.This report discloses the basic laboratory instruments will be used in each of our practices .It is of great importance to recognize and identify the different instruments and laboratory tools‚ because in this way will we be able to use them properly and also to call them by name and know why.

multiplication of different pathogenic microorganisms in the body-such as fungi‚ bacteria and viruses- the body’s reaction to it and the defense mechanisms it activates to counter these pathogens or the toxins they produce. Infections can range from simple to complex ones that can be fatal or debilitating‚ but because of the continuous researches and studies to protect the human race‚ antibiotics were discovered. Antibiotics inhibit the release of toxins of these microorganisms or simply fight against them

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%
