What are the two major groups of bacteria?

What are the two major groups of bacteria?

Bacteria are the simplest living organisms. Previously they fell under the Kingdom Moneran, but now they fall into two different Domains: Archaebacteria and Eubacteria. There are several differences between the two.

How many bacterias are in the world?

5,000

What are spiral shaped bacteria called?

Bacteria are classified according to their shape, or morphology. Spherical bacteria are known as cocci, rod-shaped bacteria are bacilli, and spiral-shaped bacteria are spirilla.

What are the different shapes of bacteria found?

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.

What shape do you catch bacteria?

spherical

What conditions does bacteria need to grow?

Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.

At what temperature will bacteria stop multiplying?

Between 4°C and 60°C (or 40°F and 140°F) is the “Danger Zone.” Keep food out of this temperature range because bacteria will multiply rapidly. Between 0°C and 4°C (or 32°F and 40°F), most bacteria will survive but will not multiply quickly.

What type of storage provides temperature enough to prevent bacteria from growing?

refrigerated

Does boiling food kill germs?

Boiling does kill any bacteria active at the time, including E. coli and salmonella. But a number of survivalist species of bacteria are able to form inactive seedlike spores. After a food is cooked and its temperature drops below 130 degrees, these spores germinate and begin to grow, multiply and produce toxins.
