Hello everyone! Introduce myself, I am the oldest microorganism in the world -cyanobacteria bacteria! Now, I am 35 billion years old, and I am the biggest elder in the entire family! Today, let me lead everyone to our "world" together!

Time passed, and when he was expected to discover me for the first time in Taikoo Rock in western Australia, I was able to see the sun again. I also have a "nickname" like humans called blue and green algae. My ability is big! Can use photosynthesis to generate energy, promote the formation of oxygen in the earth's atmosphere, and make the earth more suitable for life. This is indispensable for the "construction" of the earth and the survival of all life!

Our family is divided into eight people -bacteria, viruses, fungi, radiation bacteria, Lixi secondary toot, mycoplasma, chlamydia, and spiral. Most family members are very small. Human beings cannot be found with the naked eye. We can only see us through optical or electrical microscopes, but one of the clan can be discovered with the naked eye. For example, mushrooms, ganoderma, shiitake mushrooms ... their family is the most special among the clan.

After working hard day and night, scientists have discovered some uniqueness of our microorganisms.

First, most of the people's people are "small faces and big faces." Because we are too small, the relative surface area will be larger, which will also become our unique symbol and a "ID card" that is easier to recognize.

Second, some people will "suck more and turn fast." For example, lactose bacteria, they can decompose within one hour, which is 100 to 10000 times that of their bodies and the protein synthesis capacity of fake silk yeast is 100 times the ability of soy protein synthesis!

Third, the growth and reproduction speed is extremely high. For example, E. coli in fertility experts in the clan, his speed can be described as unparalleled.

These three points are the uniqueness of our microorganisms.

We are not only the University, but also love to help others. For example, the most important thing to make bread is to make noodles, which is indispensable for a general in our family -yeast! After his processing, the bread became large and chewy and more delicious. Among many labor and technologies, our embellishment and processing are indispensable, and humans have inadvertently helped us, let us live from them and obtain necessary nutrition, and we can survive better. Not only that, humans sometimes help us find more companions and increase our ethnic group. It can be understood that humans and microorganisms are mutually beneficial relationships. We are also an essential part of human life!

Although we have always been good with humans, we can sometimes kill a wave of harmful horses and destroy the friendship between humans and microorganisms. SARS in 2003 and the new crown of 2020 are the best proofs. These unsatisfactory microorganisms sneaked into the human world and made a blessing, which caused countless humans to be persecuted. In this regard, our microorganisms are deeply ashamed ...

Our microorganisms and humans live together in the same natural environment. Human beings are inseparable from microorganisms, and our microorganisms are always inseparable from humans. Although, sometimes there are some unpleasant "episodes", and some horses who harm groups try to destroy the "friendship" between humans and microorganisms, but we have always believed that the friendship between humans and microorganisms will never break! Let's hold our hands to support a blue sky together; live in a beautiful earth together; jointly maintain the most pure and simple friendship between humans and microorganisms!
