Some methanogenic bacteria (which are anaerobic) do have flagella. You can read more in the related link
Anaerobic bacteria do not require oxygen to live. They are able to generate energy from sources other than oxygen, such as fermentation or anaerobic respiration. Some examples of anaerobic bacteria include Clostridium and Bacteroides.
There are still some anaerobic microorganisms in existence today. Botulism is a form of anaerobic bacteria that can cause human harm.
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
Some common diseases caused by anaerobic bacteria include bacterial vaginosis, periodontal disease, and certain types of wound infections. These bacteria thrive in environments with little to no oxygen, leading to infections in various parts of the body.
Aerobic bacteria have a competitive advantage in an oxygen-rich environment because they can use oxygen as a final electron acceptor in their respiration process, which generates more energy than anaerobic respiration. This allows aerobic bacteria to outcompete anaerobic bacteria and thrive in oxygen-rich conditions.
it can be both depending on the conditions of the environment in which it lives.
A Protista can be either anaerobic or aerobic. This is because some of them live at the bottom of the ocean or in hot springs.
Not necessarily. Anaerobic bacteria play important roles in various ecosystems, such as breaking down organic matter in oxygen-deprived environments like wetlands. However, some anaerobic bacteria can also cause infections in humans if they enter the body through wounds or other means.
Bacteria do not breathe in the sense that we do, but many do require oxygen. These are called aerobic bacteria. Some bacteria will use oxygen if it is present, but can function without it. These are called facultative anaerobes. Still other bacteria will die if exposed to oxygen. These are called obligate anaerobes.
yes bacteria in some forms.Many anerobic bacteria are poisoned by Oxygen.Ex-Clostridium species
Anaerobic bacteria are important because they play a crucial role in various ecological processes, such as decomposition of organic matter in oxygen-deprived environments like wetlands and the human digestive system. Some anaerobic bacteria are also used in industrial processes, like wastewater treatment and biogas production. Additionally, certain anaerobic bacteria are pathogenic and can cause infections in humans and animals.
