Bacteria are prokaryotes, and the fundamental difference between prokaryotes and eukaryotes is that there is no formed nucleus in prokaryotic cells, and at least in all the bacteria found so far, there is no formed nucleus, so bacteria must be prokaryotes.

1. Viruses: cell-free structure, mainly composed of proteins and nucleic acids, including viruses and subviruses (viroids, viroids, prions).
Animal viruses: RNA (poliovirus, rabies virus, measles virus, mumps virus, influenza virus, HIV virus, foot-and-mouth disease virus, meningitis virus, SARS virus).
DNA (poxvirus, adenovirus, herpesvirus, iridescent virus, hepatitis B virus).
Plant viruses: RNA (tobacco mosaic virus, potato X virus, cucumber mosaic virus, barley yellowing virus, etc.).
Microbial viruses: bacteriophages.
2. Prokaryotes: with cell structure, but there is no nuclear membrane and nucleolus differentiation in the cell, and there are no complex organelles, including: bacteria (rod-shaped, spherical, spiral-shaped), actinomycetes, cyanobacteria, mycoplasma, chlamydia, rickettsia, spirochetes.
Bacteria: All the species of bacteria covered in the three books:
Lactobacilli, nitrifying bacteria (metabolic type);
Pneumococcus s, R (material basis of heredity);
Mycobacterium tuberculosis and leprosy bacilli (intracellular parasites);
rhizobia, nitrogen-fixing bacteria (nitrogen-fixing bacteria);
Escherichia coli, Bacillus subtilis, Agrobacterium aleopterasis (providing carriers for genetic engineering, and can also be used as recipient cells for genetic engineering);
Bacillus thuringiensis (provides an insect-resistant gene for insect-resistant cotton);
Pseudomonas (a superbug that breaks down oil);
Methyltrophic bacteria, Corynebacterium glutamicrum, B. flavus (metabolism of microorganisms);
Streptococci (general anaerobic type); Methanogens (strictly anaerobic), etc.
Actinomycetes: are the main antibiotic-producing bacteria. They produce a wide variety of antibiotics (85%) such as streptomycin, gentamicin, erythromycin, tetracycline, cycloserine, polyoxymycin, cyclohexamide, chloramphenicol, and fosfomycinThe mode of reproduction is conidia reproduction.
Chlamydia: Chlamydia trachomatis.
3. Sterilization: It refers to killing the cells, spores and spores of all microorganisms in a certain environment. The most commonly used method in laboratories is autoclaving.
4. Eukaryotes: complex organelles and shaped nuclei, including: yeasts, molds (filamentous fungi), mushrooms (macrofungi) and other fungi and unicellular algae, protozoa (paramecium, paramecium, amoeba, Plasmodium vivax, etc.) and other eukaryotic microorganisms.
Mold: It can be used for fermentation industry, and is widely used in the production of alcohol, citric acid, glycerol, enzyme preparations (such as protease, amylase, cellulase, etc.), sterols, vitamins, etc. In agriculture, it can be used for feed fermentation, production of auxins (such as gibtimycin), insecticidal pesticides (such as Beauveria bassiana), herbicides, etc.
Hazards such as mould and toxin production (e.g. aflatoxins are carcinogenic, Fusarium toxins may be associated with Keshan disease).Common molds mainly include mucor, rhizopus, aspergillus, penicillium, gibberella, beauveria bassiana, veinola, Trichoderma, etc.
It's a little hard, but you can tell you more about it

Bacteria are prokaryotes, and there are many differences between bacteria and eukaryotes, such as eukaryotes mean that their cells are eukaryotes, that is, there is a fixed nucleus in the cell, and there is a nuclear membrane on the outside; The cells of prokaryotes are prokaryotic cells, i.e., there is no shaped nucleus in the cell, only one nuclear region that is not surrounded by a nuclear membrane.

Eukaryotes eukaryotes are organisms made up of eukaryotic cells. Including the kingdom Protists, Fungi, Plants, and Animals. Definition Eukaryotyotes are a general term for all unicellular or multicellular organisms whose cells have a nucleus, and it includes all animals, plants, fungi, and other organisms with complex subcellular structures surrounded by membranes. >>>More
In eukaryotic cells, the ribosomal small subunit 40s first and initiates the aminoacyl tRNA structure, while the prokaryotic ribosomal small subunit 30s first binds to mRNA. >>>More
There are cells to verify eukaryotes, and there is no nucleus is the most fundamental difference between prokaryotes.
