Bacteria What are Bacteria? Bacteria are microscopic organisms whose single cells have neither a membrane-bounded nucleus nor other membrane-bounded organelles like mitochondria and chloroplasts. Another group of microbes, the archaea, meet these criteria but are so different from the bacteria in other ways that they must have had a long, independent evolutionary history since close to the dawn of life. In fact, there is considerable evidence that you are more closely related to the archaea than they are to the bacteria! [ View Link to page devoted to the Archaea.

Movie Gallery Bacteria Cell Structure They are as unrelated to human beings as living things can be, but bacteria are essential to human life and life on planet Earth. Although they are notorious for their role in causing human diseases, from tooth decay to the Black Plague, there are beneficial species that are essential to good health. For example, one species that lives symbiotically in the large intestine manufactures vitamin K, an essential blood clotting factor. Other species are beneficial indirectly. Bacteria give yogurt its tangy flavor and sourdough bread its sour taste. They make it possible for ruminant animals (cows, sheep, goats) to digest plant cellulose and for some plants, (soybean, peas, alfalfa) to convert nitrogen to a more usable form. Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle. They come in many shapes and sizes, from minute spheres, cylinders and spiral threads, to flagellated rods, and filamentous chains. They are found practically everywhere on Earth and live in some of the most unusual and seemingly inhospitable places. Evidence shows that bacteria were in existence as long as 3.5 billion years ago, making them one of the oldest living organisms on the Earth. Even older than the bacteria are the archeans (also called archaebacteria) tiny prokaryotic organisms that live only in extreme environments: boiling water, super-salty pools, sulfur-spewing volcanic vents, acidic water, and deep in the Antarctic ice. Many scientists now believe that the archaea and bacteria developed separately from a common ancestor nearly four billion years ago. Millions of years later, the ancestors of today's eukaryotes split off from the archaea. Despite the superficial resemblance to bacteria, biochemically and genetically, the archea are as different from bacteria as bacteria are from humans.

About Us Contact Us Home Enter your search terms Submit search form Sat Sep Grow Your Own Bacteria admin We always hear our mothers telling us to wash our hands with soap and warm water to kill the germs. Let us find out how true this statement is. For this experiment, we need one 4 inch sized Petri dish, water, 5 grams of agar nutrient, container to boil water, plastic wrap, cotton swab and hand sanitizer. Step 1 In a container, mix half a teaspoon of agar and a quarter cup of hot water and stir. Bring this mixture to a boil for one minute to completely dissolve the agar. In using the microwave to boil the mixture, be careful not to let it boil over. Be sure that the mixture is clear with no floating particles. Allow the mixture to cool for 3 to 5 minutes. Step 2 With an adult, carefully pour the solution into both halves of the Petri dish. Get the plastic wrap and loosely cover each Petri dish and leave it to cool and harden for at least an hour. Step 3 The fun part begins. Collect some bacteria using a cotton swab. This is usually done by rolling a cotton swab in your mouth and lightly rubbing the contaminated end on the gelled agar. Step 4 Remember you have poured the agar solution into each halve of the Petri dish. That means you have two places to grow your bacteria. Since the first half is tested with a sample from the inside of your mouth, you might want to a sample from other things such as the remote control or the computer keyboard. Or you can skip the mouth test and use other things instead. To get good samples, dampen the end of the cotton swab with water and wipe the end of the swab all over the surface to fully cover the swab with invisible bacteria.

Bacteria Bacteria Definition noun, singular: bacterium (Science: Microbiology) Microscopic single-celled organisms belonging to Kingdom Monera that possess a prokaryotic type of cell structure, which means their cells are noncompartmentalized, and their DNA (usually circular) can be found throughout the cytoplasm rather than within a membrane-bound nucleus . They reproduce by fission or by forming spores . They can practically live everywhere. They can inhabit all kinds of environment , such as in soil acidic hot springs, radioactive waste, seawater, deep in the Earth's crust , in stratosphere, and even in the bodies of other organisms Supplement Bacteria belong to Kingdom Monera , together with Cyanobacteria blue-green algae ), which are also prokaryotic . Bacteria may be classified based on their shape: spherical ( cocci ), rod-like (
