Types of Microbes
Bacteria are microscopic, single-celled organisms that have no nucleus and a cell wall made of peptidoglycan. Bacteria are the direct descendents of the first organisms that lived on Earth, with fossil evidence going back about 3.5 billion years.
All algae contain a pigment called chlorophyll a (other types of chlorophyll such as b, c and / or d may also be present) and they make their own food by photosynthesis. The chlorophyll is contained in the chloroplasts and gives many algae their green appearance.
What are Bacteria, Yeasts & Molds? 6 University of Georgia Cooperative Extension Bulletin 817 The third group – called thermophiles – grows well at temperatures between 110oF to 140oF. These bacteria can cause spoilage in under-processed canned foods. As noted earlier, microorganisms are essential in the production of certain foods.

Viruses are not "alive," that is, they cannot replicate, unless they are inside another organism. A virus is definitely too small to be seen without a microscope. Since viruses are so small (tinier than bacteria) they may be considered microbes.

Protozoa are single celled organisms. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Paramecium with its fixed shape and complex structure. They live in a wide variety of moist habitats including fresh water, marine environments and the soil.
All algae contain a pigment called chlorophyll a (other types of chlorophyll such as b, c and / or d may also be present) and they make their own food by photosynthesis. The chlorophyll is contained in the chloroplasts and gives many algae their green appearance.
However some algae appear brown, yellow or red because in addition to chlorophylls they have other accessory pigments that camouflage the green colour. Diatoms a type of algae, are found floating in the phytoplankton of the seas.
Bacteria; Archaea; Fungi; Protists; Viruses; Microscopic Animals; The human body is home to microbes from all of these categories. Microscopic plants are also considered microbes, though they don’t generally live on or in the human body.
Protozoa vs Bacteria Out of all the present biomass of the Earth, the vast majority is the microorganisms. The importance of these microorganisms would never be imaginable, given their existence could never be compared with other living beings.
• Protozoa is a sub group of Kingdom: Protista, which comes under the Eukaryotes domain, whereas bacteria could be described as an entire taxonomical domain. • Number of identified bacteria species is lower than that of protozoa. However, the actual number of bacteria species is vastly greater than the number of protozoa species. • Bacteria are prokaryotes while protozoans are eukaryotes.
