What are the types of microorganisms?

Heterotrophic facultative anaerobic, heterotrophic anaerobic, heterotrophic aerobic, autotrophic aerobic, heterotrophic anaerobic, heterotrophic aerobic.

There are many kinds of microorganisms, among which there are about 200,000 kinds of microorganisms that have been recorded, with the improvement of isolation and culture technology and the deepening of research work, new species, new genera, new families, and even new catalogs and new classes of microorganisms are constantly discovered, and these numbers are still growing rapidly. So how many kinds of microorganisms are you asking, with the development of science and technology, the depth of research, so that the types of microorganisms are more diverse, according to incomplete estimates, the types of microorganisms that have been discovered now do not exceed 10% of the total number of microorganisms in nature.

A conservative estimate is that there are 3 million species of microorganisms ......

Microorganisms are a general term for tiny organisms that cannot be observed with the naked eye. It includes four categories: bacteria, fungi, protists and viruses.

"Organisms that are tiny, simple in structure, and can usually be seen clearly with an optical microscope or electron microscope, are collectively called microorganisms. Microbe. Among the approximately 100,000 known species of microorganisms, there are not only viruses without cell structures, but also organisms in the prokaryotic kingdom, fungal kingdom, and protist kingdom.

The above is from a high school biology textbook.

It's a general term for very small creatures. Not an exact title.

What is a microorganism? How big are bacteria? How big is the new coronavirus?

These four microorganisms belong to the gram-negative and gram-positive bacteria (Escherichia coli and Bacillus subtilis) of prokaryotic microorganisms, and the single-celled yeast and filamentous fungi (brewer's yeast and Aspergillus niger) of eukaryotic microorganisms, respectively, and can be distinguished from the colony morphology and individual morphology under the microscope.

Aspergillus niger: Compared with the four types, the colonies of Aspergillus niger cultured in ordinary PDA medium are the largest, round, and the mycelium spreads rapidly, initially white, then turning bright yellow until black and thick velvet. The back is colorless or **slightly yellowish-brown, with concentric rings.

Under the microscope of insert famylan staining, the mycelium was well developed and branched, and there were septum and multiple nucleus. Vertical growth of conidia on enlarged hyphal cells (podocytes); At the apex, a swollen conidia head (parietal sac) is formed, and a double layer of small peduncles grows radially, on which clusters of conidia grow, shaped like "chrysanthemums".

Brewer's yeast: Brewer's yeast is cultured on PDA medium, with the second number of colonies, round and convex, and a milky white waxy surface. Microscopy with Melan staining shows that the thallus is oval or mango-shaped, blue or colorless, and is present alone, sometimes with buds or filigrea.

E. coli: E. coli colonies in eosin blue medium are dark purple and have a metallic sheen. Microscopic examination of Gram stain is Gram-negative, single-arranged, short bacilli.

Bacillus subtilis: Bacillus subtilis can be cultured with beef paste peptone medium, the surface of the colony is rough and opaque, white or yellowish, and the shape is round or irregular. Gram stain microscopy is gram-positive, chain-like, and rod-shaped much larger than that of E. coli.

Microorganisms are all small and medium-sized organisms that are invisible or invisible to the naked eye. The individual is tiny, the structure is simple, and it is usually necessary to use an optical microscope and an electron microscope to see clearly, which are collectively referred to as microorganisms.

Microorganisms include: viruses; Bacteria: such as Escherichia coli, Staphylococcus aureus, Bacillus subtilis, etc.; Fungi: such as molds, yeasts, etc.

Microorganisms are a group of tiny organisms that are small in size, simple in structure, and invisible to the naked eye. It is divided into 8 categories: bacteria, chlamydia, mycoplasma, rickettsia, spirochetes, actinomycetes, fungi and viruses.

Microorganisms are the umbrella term for all tiny organisms that are invisible or invisible to the naked eye. Organisms that are small in shape and simple in structure, and can usually be seen clearly with light microscopes and electron microscopes, are collectively called microorganisms. (But some microorganisms can be seen, such as mushrooms, reishi, etc., which belong to fungi.)

Characteristics: Individuals are small and generally <.

The structure is simple, there are unicellular, simple multicellular, non-cellular. The evolutionary status is low, and most of them rely on organic matter to sustain life.

Classification: Prokaryotes: Tribacteria, trisomy.

Triomycetes: bacteria, cyanobacteria, actinomycetes Trisomy: mycoplasma, chlamydia, and rickettsia.

Eukaryotes: fungi, protozoa, microscopic algae.

Noncellular: Viruses, subviruses (see Viroids, Viroids, Prions).
