Bacteria

- Key diffrents between prebiotics and probiotics : Prebiotics and probiotics are two types of bacteria which are present on all food products. These bacteria can help in dagestive system as they have the ability to keep it more healthy. These two types of bacteria have the same benefits for the health, as they can increase number of healthy bacteria in person's body, but they have some differants, too. For example, prebiotics are type of carbohydrates which have long chains of suger moleculs bonded

race. For the past 350 million years, before humans were alive, Bacteria were thriving, growing, and multiplying. These organisms are not visible to the naked eye but can be seen through a microscope. Bacteria are single-celled organisms that make up the Moneran Kingdom. According to Funk and Wagnall’s New World Encyclopedia, these archaic creatures, usually “ranging in length from less than 1 micrometer to 10 micrometers” (Bacteria), like to dwell within multiple different environments. These creatures

Genetic engineering and transformation is the “modification of an organism's original genetic composition by artificial means”(Genetic Engineering 2016). Genetic engineering and transformation involves the swapping of traits and genes between organisms to create a genetically modified organism or GMO. Genetic engineering has it’s advantages which include the prevention of disease by isolation of the gene that causes the disease, being able to take the “desirable traits” of one organism and implanting

the lowest concentration of bleach that can effectively kill E.coli bacteria? Hypothesis: The lowest concentration of bleach that effectively kills E.coli bacteria is 0.1%. Background information:  Bleach, a solution made from sodium hypochlorite and water, is a chemical used as a household cleaner. It is effective in killing bacteria and other microorganisms because when sodium hypochlorite comes in contact with viruses and bacteria, it oxidizes molecules in the cells of the germs and kills them. The

genetic material of bacteria create new characteristics through gene transfer? Introduction: Prokaryotic cells have no nucleus and no internal membrane. Because of this, they can be classified as bacteria. Prokaryotic cells are similar in structure to Eukaryotic cells, however the DNA floats in a nucleoid. Transformed bacteria consist of a recombinant plasmid and a host cell or bacteria. If the plasmid in the bacteria has a gene that is useful it can be very beneficial to the bacteria. Scientists can

Bacteria can thrive in many ways. Its growth can be influenced by temperature, pH level, water activity, supplemental compounds, absent of carbon dioxide, presence of sulfur or nitrogen, oxygen, and a supply of nutrients, or it could have a spontaneous generation. A spontaneous generation is the supposed production of living organisms from nonliving matter (Rogers & Kadner, 2015), as inferred from the apparent appearance of life in some supposedly sterile environments. There are three different cardinal

This organism is positive in oxidation because bacteria use oxygen to use lactose. The lactose tube turns from red to yellow without the mineral oil on top of the solution. Negative result for oxidation is no color change without the mineral oil. Fermentation also positive because color change from red to yellow with the mineral oil on top of solution. This mean the bacteria can use lactose without oxygen. Negative result is no color change with mineral oil on

The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems, open

The bathroom Door, which didn’t look like it could have so much bacteria. The gram staining was different than the other bacteria’s found because several chemicals and steps are used. The first step used is a frosted slide for the bacteria, secondly the loop to scoop the bacteria off the slide, and let the slide sit so it could dry thoroughly. The process of preparing the slide for the microscope had to sit so it could dry but it took more time than expected. The next option was to hold the slide

nucleus and mitochondria. Instead of a cell nucleus containing chromosomes, the DNA in bacterial cells is arranged in a single circular strand in the cytoplasm. Bacteria tend to multiply very rapidly under favorable conditions, forming colonies of millions or even billions of organisms within a space as small as a drop of water. Bacteria also spreads and can survive in extreme conditions via a process called sporulation. Sporulation involves repackaging genetic contents into small reproductive bodies
