Bacteria, such as those at the bottom

AP

1880, a Russian microbiologist named Sergei Winogradsky discovered that

mud poured into water bottles, and high in the sun turned

many different colors. He found that by adding a few simple things, such as

sheese or paper, it can control which colors appear. Here's a recipe for creating your own Winogradsky column. Materials: To >> << to do and said: Remove any stones or dirt sticks in the mud and put in bowl >>. Mix << it with water until the correspondence cream. Remove

label from your container. Put in the shredded paper and egg, add

inches of dirt, and mix well. Then fill the container

centimeter of dirt on top and cover it. Wash your hands after using the

installation. Place the container

about keeping up with the 40-watt bulb, you can go to

all the time. Every few days, briefly remove the top >> << container to express the gas (if allowed too much gas to build up, it could explode

top). If the dirt is dry on top, add

a little water. After a few weeks you will see an aura of brilliant colored

bacteria. Keep looking and you'll see that the color

develop and change over the next few months. Many species of bacteria live in

in the mud. Some of these destroyers, which are nutrients

through destruction of organic materials such as paper and egg thing. In the process of decomposition, all the oxygen at the bottom of the vessel

used. More >> << bacterial photosynthesis. Blue-green bacteria, at the top of the mud using a >> << a column of light carbon from carbon dioxide and hydrogen

Carbon dioxide is released when they should decomposers break

paper and eggs. What's going on

flourished. It was not until about two billion years ago

that the blue-green bacteria filled the atmosphere with the photosynthetic oxygen >> << product waste. This is actually driven by other types of bacteria

in places where there is no oxygen in the mud and sediment

, , and (more recently) on the insides of animals and plants. But these

oxygen-phobic bacteria continue to play a key role. Some take

participate in the global sulfur cycle. Other transformations of nitrogen in the form
