An obligation is a requirement to take some course of action, whether LEGAL OR MORAL
If they are obligate aerobes that means they require 02 to survive.
It depends on the bacteria. Cyanobacteria are a good example of a bacteria that can. There are obligate anaerobes, obligate aerobes, and organisms that can live with or without it.
obligate aerobe
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.
Facultative anaerobes does not need o2 to grow but can also grow with o2. Obligate anaerobe cannot grow at all in the presence of o2.
Obligate anaerobes do not need or use oxygen as a nutrient. In fact it is a toxic substance to them which either kills or inhibits their growth. Thioglycollate allows obligate anaerobes to grow because it consists of sodium thioglycollate, thioglycollic acid and L-crystine which reduce oxygen to water. This creates an anaerobic environment allowing obligate anaerobes to grow.
obligate aerobes.
An obligate parasite can only live inside a cell. This includes viruses and intracellular bacteria. A facultative parasite can live inside or outside of a cell.
a.Ficus (fig) trees and fig waspsb. Outcome of obligate mutualism
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.
There is a bona fide need, and the adjustment is within scope
Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
