Learn about planets outside our solar system through Exoplanets and Alien Solar Systems by Tahir Yaqoob, Ph.D., a book in our online store book collection.

The Domain Eubacteria

Each Eubacteria is a tiny prokaryotic cell.

Some can make food from sunlight through photosynthesis. Cyanobacteria, also called blue-green algae, are able to do this. They have been living in the oceans of our planet for over 3 billion years!

Some Eubacteria can cause health problems like strep throat and food poisoning. Bacteria such as E.coli and Salmonella are sometimes found in undercooked meat and eggs and can make people sick.

People have found that some types of Eubacteria can be very useful. Some are used at wastewater treatment plants to help clean the water. Some are good to eat, such as those in yogurt. Others are also used to make grapes into wine and milk into cheese.
