Bacteriology at UW-Madison Bacteriology 303 Main Page Biological Identity of Procaryotes INTRODUCTION What is a procaryote (or prokaryote )? What does it mean in biology to be a procaryotic cell? What is covered in procaryotic microbiology ? What is the significance and position of procaryotes in the living world? What is the importance of studying the biology of procaryotes? These questions are answered in this article, provided as an introduction to Bacteriology 303 , the beginning course in Procaryotic Microbiology which is taught at the University of Wisconsin-Madison. It appears that life arose on earth about 4 billion years ago. The simplest of cells, and the first types of cells to evolve are procaryotic cells organisms which lack a nuclear membrane . The Bacteria are the best known and most studied procaryotes, but recently the discovery of a second group of procaryotes, the Archaea , has provided evidence of a third cellular domain of life and new insights into the origin of life itself. For approximately 2 billion years, procaryotic-type cells were the only form of life on Earth. The oldest known sedimentary rocks, from Greenland, are about 3.8 billion years old. The oldest known fossils are procaryotic cells, 3.5 billion years in age, found in Western Australia and South Africa. The nature of these fossils, and the chemical composition of the rocks in which they are found, indicate that lithotrophic and fermentative modes of metabolism were the first to evolve in early procaryotes, and that photosynthesis developed in procaryotes at least 3 billion years ago.

Human Genome Explore human genome resources or browse the human genome sequence using the Map Viewer The SNP Database Single nucleotide polymorphisms (SNPs) are the most common genetic variations and occur once every 100 to 300 bases. It is expected that SNPs will accelerate the identification of disease genes by allowing researchers to look for associations between a disease and specific differences (in the form of SNPs) for a given population. dbSNP is a GenBank-independent database for SNP information.

Index to this page Nitrogen Fixation Atmospheric Fixation Industrial Fixation Biological Fixation ... Are the denitrifiers keeping up? The Nitrogen Cycle All life requires nitrogen-compounds, e.g., proteins and nucleic acids. Air, which is 79% nitrogen gas (N ), is the major reservoir of nitrogen. But most organisms cannot use nitrogen in this form. Plants must secure their nitrogen in "fixed" form, i.e., incorporated in compounds such as: nitrate ions (NO ammonia (NH urea (NH CO Animals secure their nitrogen (and all other) compounds from plants (or animals that have fed on plants). Four processes participate in the cycling of nitrogen through the biosphere: nitrogen fixation decay nitrification denitrification Microorganisms play major roles in all four of these. Nitrogen Fixation The nitrogen molecule (N ) is quite inert. To break it apart so that its atoms can combine with other atoms requires the input of substantial amounts of energy. Three processes are responsible for most of the nitrogen fixation in the biosphere: atmospheric fixation by lightning biological fixation symbiotic relationship with plants industrial fixation Atmospheric Fixation The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.

89. The Scientific Method of the universe, and the idea that ulcers are caused by stress has been replacedby the idea that ulcers are caused by bacterial infection. biology, 5 th Ed. http://biology.clc.uc.edu/courses/bio104/sci_meth.htm

The Scientific Method The following steps make up the Scientific Method . These steps make up a method which may be used to logically solve problems in many other areas of life. Françesco Redi and Louis Pasteur used the scientific method to disprove the idea of spontaneous generation. First, though, do you see any animals in this picture? (if so, click on them) If you were really in that place and trying to figure out what you were seeing, you could use the scientific method to study the “problem.” (There is a link to an explanation of the photograph near the bottom of this page.) Observation: For centuries, people based their beliefs on their interpretations of what they saw going on in the world around them without testing their ideas to determine the validity of these theories — in other words, they didn’t use the scientific method to arrive at answers to their questions. Rather, their conclusions were based on untested observations. Among these ideas, since at least the time of Aristotle (4th Century BC), people (including scientists) believed that simple living organisms could come into being by spontaneous generation . This was the idea that non-living objects can give rise to living organisms . It was common “knowledge” that simple organisms like worms, beetles, frogs, amd salamanders could come from dust, mud, etc., and food left out, quickly “swarmed” with life. For example:

90. Oxygen Requirements Of Bacteria Aerobes are bacteria that require oxygen. agar = polysaccharides used togel liquids for bacteria media and human foods including ice cream. http://www.disknet.com/indiana_biolab/gloss.htm

Revised 1997 Sep 3 Glossary Some definitions include a link to a page giving more information about the word. aaaa acid = any proton donor (H+); low pH, neutralize bases. Examples: HCl, vinegar, -COOH, aerobic = oxygen present. Aerobes are bacteria that require oxygen. agar = polysaccharides used to gel liquids for bacteria media and human foods including ice cream. Does not melt at room temperature like gelatin. Only a few marine bacteria can digest agar. Agar is obtained from seaweeds (algae) by heating, acid, and freezing. Gelling temperature varies. alga = single celled green plants usually growing in water; often in long chain, visible to naked eye. allergy = an immune reaction of the body which causes discomfort and possible harm. ambient = surrounding. Ambient temperature would be the room temperature. amino acids = organic acids bearing -NH group; building blocks of proteins. anaerobic = oxygen not present or depleted. Anaerobes are bacteria which are able to grow in the absence of oxygen provided suitable reducible compounds are present to accept electrons. antibodies = several sizes of structurally similar protein molecules which are able to bind to specific proteins or other substances; forming a main line of defense in animals against foreign items.

Bacterium Cell Label Me! Printout Answers EnchantedLearning.com Bacteria Animal Cells Plant Cells Bacteria are microscopic (very tiny) organisms that are unicellular (made up of a single cell). Bacterium is the term for a single bacteria. Evolution of Bacteria : These primitive organisms were among the first to appear on Earth; bacteria evolved roughly 3.5 billion years ago. The oldest-known fossils are those of bacteria-like organisms. Discovery of Bacteria : Bacteria were unknown to people until the 1600s, when Antony van Leeuwenhoek first observed them in his newly-made microscope. Cells of Bacteria : The cells of bacteria are different from those of plants and animals in many ways, the most obvious of which is that bacteria lack a nucleus and other membrane-bound organelles (except ribosomes). Unlike animals and plants, bacteria have pili, flagella, and most have a cell capsule. Bacterial cells include the following: basal body - A structure that anchors the base of the flagellum and allows it to rotate. capsule - A layer on the outside of the cell wall. Most but not all bacteria have a capsule.

100. Bacteria 3, (1994) 14Ð18. Flannery, Maura C. Back to bacteria The AmericanBiology Teacher 59 (June 1997) 370Ð37. Maggs, Dr. A. bacteria http://www.amnh.org/nationalcenter/youngnaturalistawards/1998/bacteria.html

by: Rachel Age 13 Ohio S Even though there are 2.5 billion bacteria in one gram of soil, you may never see a single bacteria in your entire life. If you lined 10,000 bacteria up, side by side, it would only make up 2.5 centimeters of space and could only be seen under a powerful microscope. Even though bacteria are extremely small, they are found nearly everywhere. Bacteria are even found in the Dead Sea. For instance, the bacteria that causes acne can be found on a pay phone. There are seven different kinds of bacteria on a locker room shower floor. On a movie theater seat and a school lunch table there are five different kinds of bacteria. Even though bacteria are so tiny, they play a very large role in their ecosystem. Every living thing would not be here today if it were not for bacteria. Decomposing is one of the most important jobs bacteria do. This is hawk eats rabbit eats grass eats decomposed hawk also called mineralization. When an organism dies in the wild, it just sits and rots. What is happening is that bacteria are releasing carbon to the atmosphere which plants use. With no carbon dioxide there would be no photosynthesis, which narrows down toÉno food. Instead of this catastrophe, bacteria do us a huge favor. By decomposing the dead organisms, the bacteria release essential nutrients into the air and soil. The simpler material made by decomposition can be used by both autotrophic and heterotrophic organisms. Autotrophs use it to help them make food and heterotrophs use it as food. As you can tell, the bacteria that decompose are very important to the earth's ecology. If these bacteria disappeared, everything would suffer greatly. The cycle goes like this: The grass is eaten by a rabbit. Then the rabbit is eaten by the hawk, then the hawk dies. After the hawk dies, bacteria decompose it and returns it to the grass that the rabbit eats, and it all starts once again.
