The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses —are summarized below.
What are the main types of microbes?
Microbial diversity is truly staggering, yet all these microbes can be grouped into five major types: Viruses, Bacteria, Archaea, Fungi, and Protists .
What are the 3 types of microbes and their characteristics?
Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. Microorganims are widespread in nature and are beneficial to life, but some can cause serious harm. They can be divided into six major types: bacteria, archaea, fungi, protozoa, algae, and viruses .
What are 3 characteristics of a microbe?
Bacterial species are typified by their diversity. There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size.
What are the 3 types of microbes found in food?

Which organism is smaller than bacteria?
Viruses are even smaller than bacteria. They aren’t even a full cell. They are simply genetic material (DNA or RNA) packaged inside of a protein coating.
What is microbial life?
Microbial Life: A Universe at the Edge of Sight takes visitors on a multimedia journey into this fascinating, invisible realm where bacteria and other microbes bustle about their lives, interacting with one another and with organisms of all sizes in every corner of the globe.
What are the 7 types of bacteria?
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes) . They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.
Which are the most common microbes on Earth?
The most common types are bacteria, viruses and fungi . There are also microbes called protozoa. These are tiny living things that are responsible for diseases such as toxoplasmosis and malaria.
What are 3 characteristics of Archaea?
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat; (3) the occurrence of ether linked lipids built from phytanyl chains and (4) in ...
What are 5 characteristics of viruses?
These are: 1) attachment; 2) penetration; 3) uncoating; 4) replication; 5) assembly; 6)release. As shown in , the virus must first attach itself to the host cell.
What would happen if we rid the world of bacteria?
Bacteria are vital in keeping nitrogen cycling through the ecosystem , and nitrogen is vital to plant growth. ... Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn’t return their nutrients back to the system.

- Headache.
- Stiff neck.
- Confusion or changes in alertness.
- Loss of balance.
- Convulsions.
What does Fattom stand for?
FATTOM is an acronym used to describe the conditions necessary for bacterial growth: Food, acidity, time, temperature, oxygen, and moisture . Foods provide a perfect environment for bacterial growth, due to their provision of nutrients, energy, and other components needed by the bacteria.
What kinds of bacteria grow on food?
- Norovirus.
- Salmonella.
- Clostridium perfringens.
- Campylobacter.
- Staphylococcus aureus (Staph)
