How do azotobacter make anaerobic environment for nitrogenase enzyme?
by concentrate oxygen using leghemoglobin
What type of organism is responsible for performing the majority of nitrogen fixation?
There are two ogranisms that are nitrogen fixers:Free-living (non-symbiotic) bacteria, which live in the soil. This includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and such genera as Azotobacter, Beijerinckia, and ClostridiumMutualistic (symbiotic) bacteria, which live live in nodules in the roots of plants. This includes Rhizobium,associated with leguminous plants, and Spirillum lipoferum,associated with cereal grasses.Nitrogen fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds that plants can use in the soil.
What is a nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
What is an explanation of the nitrogen cycle?
Nitrogen cycle begins like every other cycle in the Biogeochemical cycle.Nitrogen is an unstable gas in it's octet form but the normal Nitrogen is stable so during nitrogenation;which is the formation of free Nitrogen in the atmosphere,nitrogen is being broken down during lightening and thunderstorms so,it becomes free in the atmosphere and can now combine with other compounds.During rainfall,Nitrogen combines with water to form Nitric acids and with sulphur to form NITROGEN SULPHIDE.These two compounds of Nitrogen are then incorporated into the soil during Nitrogen fixation. The soil alone can not convert this Nitrogen into usable or rather consumable Nitrogen so only root noddles of leguminous plants like Beans can convert this nitrogen into usable one because they have nitrogen fixing bacteria like Rhizobium nigricans . But there are also some free living bacteria in the soil named Azotobacter which help in converting this nitrogen in the soil into usable Nitrogen so that plants can use it for growth.When these nitrogen compounds have been converted into usable nitrogen,plants now use it to produce food energy which are later on eaten upon by animals for growth.This process is called feeding like we all know.When these plants and animals die,their dead bodies decay and are embedded into the soil.Micro organisms now eat on these dead bodies.A process called putrefaction.These decomposed matters are later on converted into Ammonia in a process called Amonification by nitrogen fixing bacteria.The same Ammonia is converted into Nitrites and later on into nitrates by Nitrosomonas and Nitrobacters bacteria respectively and some of the nitrates are lost into the underneath soil a process called leaching during erosion by water and the nitrates are also absorbed by plants during food chain a process called Assimilation.The nitrates and nitrites are later sent back into the atmosphere during denitrification which is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions. They use the nitrate as an electron acceptor in the place of oxygen during respiration. These facultatively anaerobic bacteria can also live in aerobic conditions.Without forgetting that during thunder storms,Nitrogen is also sent back into the atmosphere.
What is size of azotobacter?
Azotobacter's cells are large rods, at least 2 microns in diameter
What has the author Edward P Lhuede written?
Edward P. Lhuede has written: 'Noise levels in Australian sawmills' 'Effect of gibrel on Azotobacter chroococcum' -- subject(s): Azotobacter, Gibberellins
How do azotobacter make anaerobic environment for nitrogenase enzyme?
by concentrate oxygen using leghemoglobin
Why is only mannitol used in ashby's mannitol broth?
MANNITOL IS CARBON SOURCE & AZOTOBACTER can fix nitrogen non- symbiotically

What does azotobacter eat?
nitrogen, are you stupid? You have to have a kid in 7th grade to answer your question? I think college may serve your education needs better than wiki answers.
Which organism fixes nitrogen to the soil?
rhizobium, frankia, azospirlium, azotobacter
Plants transfer nitrogen in the nitrogen cycle?
Because leguminous plants are those plants which have nitrogen fixing bacteria in their roots in the modules of nitrogen. thus to fix the nitrogen to the soil or in crops is the work of those bacteria namely rhizobium and azotobacter thus without these plants we wont have these bacterias and alos the nitrogen
What is an important role of bacteria?
Bacteria are the most abundant organisms in the world. Scientists believe that bacteria helped create the earth's atmosphere. By producing so much life-producing oxygen, bacteria eventually made the atmosphere habitable for all creatures, including humans. Bacteria are importnant to the planet as decomposers of dead organic matter, processors of nitrogen, and makers of medicine

What is the role prokaryotes play in nitrogen recycling?
1. Bacteria that nitrifies ammonium compounds in the soil (called "nitrifying bacteria"). Example: Nitrosomonas. 2. Bacteria that nitrifies nitrites (NO2-) in the soil (also called "nitrifying bacteria"). Example: Nitrobacter. 3. Bacteria that denitrifies nitrates (NO3-) in the soil (called "denitrifying bacteria"). Example: Pseudomonas denitrificans. 4. Bacteria that "fixes" nitrogen (called "nitrogen-fixing bacteria"). Examples: Rhizobium (which is symbiotic) and Azotobacter (which is free-living). 5. You also have bacteria that putrefies nitrogenous waste (like urea) and the protein in dead organisms. This type of bacteria is called putrefying bacteria.
How do you describe five instances in the nitrogen cycle where bacterial action is important?
