What is the approximate percentage of microorganisms cultivated by humans in all microorganisms?

At present, about 150,000 species have been identified by humans, which is much smaller than the number of animals and plants, but it is generally believed that less than 1% of microorganisms found in nature are found by humans

Summary. Extended information: At present, the microorganisms that people can cultivate, observe, and study only account for about 1% of the total microbial species on our earth, that is, there are still 99% of microorganisms waiting for us to know. This proportion is much higher than that of animals and plants.

Microorganisms are characterized by their small size. Don't say that the smallest virus is only 20 nanometers; A bacterium is 1000 nanometers, the volume is about one cubic micrometer, and the total volume of a trillion (1012) bacteria is only one cubic centimeter, and the total weight is about 1 gram. But their combined surface area is close to 6 square meters.

And one of us adults weighs 60 kilograms and has a body surface area of less than one square meter.

Hello. The proportion of microorganisms cultivated by humans is about less than 1% of all microorganismsExtended data: At present, the microorganisms that people can cultivate, observe, and study only account for about 1% of the total microbial species on our earth, that is, 99% of microorganisms are waiting for us to know.

This proportion is much higher than that of animals and plants. The characteristic of microorganisms is that the ridge is small. Don't say that the smallest virus is only 20 nanometers; A bacterium is 1000 nanometers, the volume is about one cubic micrometer, and the total volume of a trillion (1012) bacteria is only one cubic centimeter, and the total weight is about 1 gram.

But their combined surface area is close to 6 square meters. And one of us adults weighs 60 kilograms and has a body surface area of less than one square meter.

The proportion of microorganisms cultivated in human dust to all microorganisms is probably ().

Positive and dispersive answer: less than 1%.

Microorganisms include bacteria, viruses, fungi and some small protists, microalgae, etc., including a large group of organisms, it is small, closely related to humans, in the textbooks in Chinese mainland, microorganisms are divided into the following 8 categories of bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, spirochetes:

1. Bacteria are one of the main groups of organisms, with a diameter of up to 5 microns;

2. Viruses, most viruses have a diameter of 100 nanometers, the diameter of larger viruses is 300 to 450 nanometers, and the diameter of smaller viruses is only 18 to 22 nanometers;

3. Fungi, when in the vegetative body, the diameter of the hyphae is generally 2 to 30 microns, and the maximum can reach 100 microns.

4. Actinomycetes are a proto-Jianjingqing nuclear biological group, which mainly reproduces by spores, followed by rupture reproduction, and the species are diverse, and there is no unified data on size;

5. Rickettsia, microns to microns long, microns to microns wide;

6. Mycoplasma, to micron in size;

7. Chlamydia, with a diameter of to microns;

8. Spiral body, the diameter is generally to microns.

Microorganisms have been on Earth since 3.2 billion years ago. Just because of their small size, until the mid-19th century Leeuwenhoek.

It was only after the invention of the microscope that the microbial world revealed its fascinating mysteries to mankind.

To say that they are small is not an exaggeration at all. They are small, so small that they are not even visible to the naked eye, because we can only see things above 1 10 millimeters with the naked eye. And tens of thousands of microorganisms are piled together, and there is only one grain of millet.

It's so big, you can see how small they are.

Although the volume of microorganisms is so small, it can still be measured. Of course, the measuring tool cannot be the ordinary ruler used by ordinary families or students today. Because these rulers are the smallest units.

is millimeters, which are used as the unit of length of microorganisms.

It's really overkill. In general, to measure microorganisms, we use micrometers (millimeters) or nanometers (10-6 millimeters). How big is a micron?

Divide 1 mm into 1000 equal parts, one of which is 1 micron. Divide this little bit into 1,000 parts, and take one of them, which is 1 nanometer.

Microorganisms can decay wood, causing annual losses in the UK alone.

Three or four hundred million dollars! Moreover, it can multiply on the plastic surface of the computer's electronic circuit, causing the entire system to malfunction and cause immeasurable damage!
