Important Roles That Bacteria Plays In Our Lives
Bacteria live in our irrigation, our food, and our bodies. Much what we know about bacteria was learned by scientists fight bacterial diseases. But of the thousands of types of bacteria only a minority cause diseases. Many bacteria do things that are important and even helpful to us.
Great for the Environment
Life as we -know it could not exist without bacteria. Bacteria are very important to the health of Earth. They help recycle dead animals and plants. Bacteria also play an important role in the nitrogen cycle.
Most living things depend on plants. Plants need nitrogen! grow. Nitrogen gas makes up about 78% of the air, but most plants cannot use nitrogen directly from the air. They need to take in a different form of nitrogen. Nitrogen-fixing bacteria take in nitrogen from the air and change it to a form that plants can use. This process, called nitrogen fixation,.
Bacteria in Your Food
Believe it or not, people raise bacteria for food! Every time you eat cheese, yogurt, buttermilk, or sour cream, you are also eating bacteria. Lactic acid-producing bacteria break down the sugar in milk, which is called lactose. In the process, the bacteria change lactose into lactic acid. Lactic acid preserves and adds flavor to the food.
Good for Human
Bacteria do much more than help keep our environment clean. Bacteria also help produce many of the foods we eat every day. they even help make important medicines.
Bacteria in the Gut
There are good bacteria and bad bacteria in our gut or the digestive system. If a person has too much bad bacteria in their gut, that can cause illness. It is has been found that most of our immune system is in our gut / digestive system. If there is an over abundance of bad bacteria in the gut, that can cause illness throughout the entire body.
It is important to build up the good bacteria in the gut. This can be done by eating plenty of vegetables, fruits and a good quality yogurt like Greek yogurt, plus taking probiotics. There are also prebiotic foods that can help with the absorption of probiotics. Certain medicines, especially antibiotics can kill all bacteria in the gut, and it is important to build up the good bacteria again. You can find many good quality probiotics like Ulimate Flora by RenewLife.
Cleaning Up Environment
Bacteria and other microorganisms are also used to fight pollution. Bioremediation means using microorganisms to change harmful chemicals into harmless ones. Bioremediation is used to clean up hazardous waste from industries, farms, and cities. It is -also used to clean up [oil spills. The Scientists also are use bacteria to remove pollutants from the soil.
Recycling leaves: have you ever seen dead leaves and twigs on a forest floor? These leaves and twigs are recycled over time with the help of bacteria. Decomposer bacteria break down dead plant and animal matter, peaking down dead matter makes nutrients available to other living things.
Humans couldn't live without bacteria, but bacteria can also cause harm. Scientists learned in the 1800s that some bacterial are pathogenic . Pathogenic bacteria are bacteria that cause disease. Pathogenic bacteria get inside a host organism and take nutrients from the host's cells. In the process,: harm the host. Today, we are protected from many bacterial diseases by vaccination. Many bacterial diseases can also be treated with antibiotics.
Scientists change the genes of bacteria, or any other living thing, the process is called genetic engineering. Scientist have been genetically engineering bacteria since 1975. In that year, researchers put genes from a frog like the one in into the bacterium Escherichia coli.|The bacterium then started making copies of the frog genes, Scientists can now engineer bacteria to make many products,; such as insecticides, cleansers, and adhesives.
What's the best way to fight disease-causing bacteria? Would you believe that the answer is to use other bacteria? Antibiotics are medicines used to kill bacteria and other micro organisms. Many antibiotics are made by bacteria.
The human body needs insulin to break down and use sugar! and carbohydrates. People who have diabetes do not make enough insulin. In the 1970s, scientists discovered how to put) genes into bacteria so that the bacteria would make human insulin. The insulin can then be separated from the bacteria and given to people who have diabetes.
There are now many doctors calling for the decrease in the use of antibacterial soaps. Many of us grew up playing in the dirt, and then just using soap to clean up. It has been shown that playing in the dirt as a child can help build up the immune system. Antibacterial soaps and surface cleansers can actually hurt the immune system.
