Bacteria Kingdom Fermenting Bacteria Phylum: Streptococcus Like all other bacteria, streptococcus is a single-celled organism. It cannot tolerate oxygen so it finds places to live which are not exposed to the atmosphere. One such place is inside the human body. A drawing of bacteria These three bacteria are drawn hundreds of times bigger than their normal size. It would take 1000 of them lined up from end to end to measure one millimetre. As soon as it enters the body, a bacterium will begin to reproduce by simply splitting in two. The two bacteria will then divide to make a total of four. The next division will produce a total of eight, then sixteen, then thirty-two. When the population of bacteria attains a certain number in an area of the body, they produce an infection. Fever will begin and antibiotics are often taken to kill the bacteria. Bacteria may be extremely small, but they are capable of making people very sick. O p e n ... e

Introduction to the Bacteria Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira , which causes serious disease in livestock). However, certain bacteria, the actinomycetes, produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies, or on the roots of certain plants, converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to break down dead organic matter; bacteria make up the base of the food web in many environments. Bacteria are of such immense importance because of their extreme flexibility, capacity for rapid growth and reproduction, and great age - the oldest fossils known, nearly 3.5 billion years old, are fossils of bacteria-like organisms.

Overview Research Development Dissemination ... Theoretical and Computational Biophysics Group Quantum Biology of the PSU NIH Resource for Macromolecular Modeling and Bioinformatics Click on the figure for a 212 kB version of the PSU Figure produced with VMD In general, biological pigments are non-covalently bound to proteins, forming the so-called pigment-protein complexes. The pigment-protein complexes are organized as the photosynthetic unit (PSU). The bacterial PSU consists of two types of pigment-protein complexes: the photosynthetic reaction centers (RCs) and the light-harvesting complexes. The main function of the light-harvesting complexes is to gather light energy and to transfer this energy to the reaction centers for the photo-induced redox processes. In most purple bacteria, the photosynthetic membranes contain two types of light-harvesting complexes: light harvesting complex I (LH-I) and light harvesting complex II (LH-II). While LH-I is tightly bound to the photosynthetic reaction centers, LH-II is not directly associated with the reaction centers, but transfers energy to the reaction centers via LH-I. Purple bacteria are great masters of harvesting light. Nearly all the energy gained by the absorption of a photon is transferred on to the reaction center. To illustrate how purple bacteria achieve such high efficiency, we trace the way of a photon (and its excitation energy, respectively) through the light-harvesting system. On this way we will point out the remarkable geometrical features that serve the process of harvesting light. It is the goal of our research to understand how these geometrical features translate into physical properties that ideally support the biological function. It will be shown that purple bacteria exploit elegant quantum physics, the working of which were only fully understood recently after the discovery of the structures of light-harvesting complexes and investigations into their electronic excitations.

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.
