How does oxygen kill obligate anaerobic bacteria?
According to the Wikipedia article at: http://en.wikipedia.org/wiki/Obligate_anaerobe there are several reasons that obligate anaerobes are killed by oxygen. One common answer, that they do not have the protective enzymes, catalase and superoxide dismutase, is not true for some anaerobes. The article provide three alternative explanations, based on bacterial metabolic pathways.
What are bacteria that cannot live without oxygen called?
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
What is pure breeding?
Pure breeding is the process of selectively breeding animals to produce some desired, different, animal.
When more than one colony type appears in a pure culture what are the most likely sources of the extraneous organisms?
1. It's not a pure culture or 2. Some of the colonies are descended from "transformed" individuals or 3. Some of the colonies are descended from mutant individuals
Bacteria that are poisoned by oxygen?
some nitrogen fixing bacteria are poisoned by oxygen. also some bacteria that live near glacial ice are affected .they have developed protective enzymes as when ultraviolet rays hit glacial ice ,oxygen has been discovered as being released in molecular form.
Is mycoplasma aerobes or anaerobes?
most of them are facultative anaerobes. oxygen is not pioson for them. M. pneumoniae is aerobe. there are also some strict anaerobes in bovine rumen.
Did any Africans invent alphabetic writing?
No pure alphabets, but there are some abugidas that were invented by African cultures, for example, the Amharic abugida.
What kingdom is an organism that can survive without oxygen in?
Some bacteria and protists called anaerobes can live without oxygen. Three kingdoms have organisms that have anaerobes- kingdom bacteria, kingdom archaea, and kingdom protista
What would you need to do to determine whether bacteria growing on a petri plate are anaerobes?
some sense
Is there a life that doesn't need oxygen?
Yes. There are organisms called anaerobic bacteria which do not need oxygen. To some organisms, called obligate anaerobes, oxygen is actually toxic. The first living things on Earth were obligate anaerobes.
Do obligate anaerobes express superoxide dismutase?
No, obligate anaerobes do not express superoxide dismutase. This is because these organisms do not encounter oxygen in their natural environment and therefore do not need enzymes to detoxify reactive oxygen species like superoxide.
Who cleans the monuments in Washington DC?
Some are maintained by the city of Washington, some are maintained by the District of Columbia, and some are maintained by the Federal goverment.
What are some New York Cultures?
cultures of New York State cultures of new york state
Does clostridium botulinum need oxygen to survive?
No, anaerobes do not require oxygen to survive, for they do not carry out cellular respiration with oxygen as the final electron acceptor. Rather, they typically carry out either fermentation or anaerobic respiration, which requires no oxygen, but still provides a small amount of energy.
What are some Alaskan cultures?
